Detecting Cataracts with Remote Wavefront Aberrometry

How the SVOne is detecting cataracts with remote Wavefront Aberrometry

Detecting cataracts and referring for comprehensive care:

Our wavefront refraction technology has the ability to detect early signs of cataract development. In this case, we demonstrate how our optometrists/ophthalmologists use Smart Vision Labs’ telemedicine platform to detect signs of early-stage cataracts and send for a comprehensive cataract referral.

The patient is an elderly gentleman visiting one of SVL’s partner eyewear retail locations. Patient went through the wavefront refraction test, and the data was reviewed by a licensed ophthalmologist. The doctor referred the patient for cataract evaluation. There are 3 data points standing out about the patient.

  1. Patient age is 75 years old, in the high possibility zone of developing cataracts.
  2. Patient’s unaided Visual Acuity for both eyes is 20/200.
  3. The wavefront images for both OD and OS show symptoms of light blockage in lens pathway; indicated by the red circles.

Customer Spotlight: Becoming Profitable in 3 Months

Customer Spotlight with National Optical

How long did it take you to make a profit with the SVOne?

I broke even in about three months. I twas quite fast! We used to lose clients when they were told they had to wait for the one day that the doctor was in. With SVOne, however, I can do the exams every day. This has made business more stable and consistent. It’s less stressful and I save $500/week on human resources and other expenses.

Who is your average customer?

Our location is in a supermarket in Brooklyn that is busy with shoppers, so I get a variety of customers who come from diverse backgrounds. I get a mix of both walk-ins and word of mouth referrals.

How do customers respond to Smart Vision Exams? 

They love it for the convenience, speed, and accuracy. The exams take only five minutes. Vision exams used to be a three-person or two-person process. Now, it’s a one-person process. It’s more personable this way.  Since I am the only one doing the refractions and recommending lenses, they trust me more, and I can form closer relationships with them.  I have built a very strong personal connection with a lot of my clientele after using the SVOne device.

What tips about using the SVOne can you share?

The darker the room, the better. Turn off the lights as much as possible. I take the machine into a dark room so that I can catch the refraction quickly.

Increasing Accessibility


How did SVOne help you to Increase your customer base?

By virtue of being an all-in-one optical solution. Instead of having customers go to an eye doctor, I’m a one-stop shopping experience. SVOne validates my service and professionalism. I am able to reassure and talk with the patient about their optical needs.

How do you use the device to increase revenue?

Some people don’t want to go to an eye doctor. Some customers like my service because of that. Some of my customers are immobile and are at home; I can go to them. I charge less on the vision test and make up for it by producing more prescriptions, which helps people get in the door.

Who is your average customer?

My average customer ranges from 25 to 55 years old. I have some patients with expired prescriptions who can’t afford a full exam. I talk with them about how it’s a visual test and how the device sends the information to an ophthalmologist.

How have your customers responded to using SVOne?

They are really impressed with it. I haven’t had to do many prescription redos. I’ve been remarkably surprised by that! My customers haven’t had many issues with the test results.

What tips about using the SVOne in your practice can you share with us?

I think the main tips are always clean the eyepiece in front of the customer. It’s important to always be professional. I talk with patients about centering the red light and then looking through the device to 10 feet away. It’s the little things that come with aligning the patients that take practice.

Can you tell us about some of your most rewarding experiences?

Last month, I was in a small home with a family of four. I was in their kitchen doing a vision test. I had their full trust while helping them with their vision needs. It was so amazing. It was much better than a cold unfamiliar establishment. You can‘t imagine this interaction outside someone’s home. Once you have their trust, it’s an amazing experience.

Moves with Eyes in the Title - Smart Vision Labs

"Eye" Love Movies!

“Eye” Love Movies!

Do you ever feel that there are eyes all around you? Are they watching you or are you watching them? If an eye blinks in the forest and no one is around, is that called an invisible blink? Does someone have to see your eyes so your eyes can see?


If you happen to be a Hollywood producer, these questions make perfect sense. And they may even be the idea behind yet another movie named after the eye. Did you know that many film titles have the word “eye” in them? Let’s take a look.

Kinds of Eyes

Movies have been made about all kinds of eyes.


Starry Eyes is a horror film about a young woman suffering from trichotillomania, or hair pulling. She desperately wants to become a famous actress so she makes a deal with the devil. You probably don’t even need to have your eyes open to know how this turns out. In fact, you may want to shut your eyes if you don’t like gore.


Snake Eyes is a thriller that didn’t have much luck at the box office even with Nicolas Cage in the starring role. The plot has some of the usual characteristics of this genre, like a murder conspiracy, a shady police detective, and a casino, but the action didn’t widen the eyes of moviegoers in shock.




Angel Eyes literally soared above these movies with a better plot, memorable music score, and outstanding acting. It’s about a mysterious man who develops a relationship with a female police officer. Each of them has trauma from their past that they deal with together. Moviegoers definitely had a tear or two coming from their own eyes.

Location of Eyes

If you thought movies only dealt with eyes that are set in the head, then you are wrong. According to Hollywood, eyes can be in the sky or in the hills.

eye_in_the_sky_2015_film_poster Eye in the Sky is a thriller about drone warfare. Realistic enough to be scary, this film had people widening their eyes in fear.

The Hills Have Eyes is at the other end of reality. This is a horror movie about murderous mutants. It’s always a good idea to keep an eye open in case you see a pack of them coming at you.

Whose Eyes?

Movie titles have featured eyes by a stranger and a mother. And these films are eye-opening, as in shocking. You may want to hold off on eating popcorn.

91xea44p0kl-_sy445_ The Eyes of My MotherThe Eyes of My Mother is not for the faint of heart. It’s considered arthouse horror and is not a my-mother’s-eyes-love-me kind of movie.

Eyes of a Stranger is a slasher film that may make moviegoers hesitate about leaving their seats to go to the bathroom.



So What’s the Deal with Movies and Eyes?

If this was a mathematical equation, the answer would be movies plus eyes equals an audience. But there is more to it than that. Merely watching a movie doesn’t make it great; moviegoers have to use more than the physical aspects of their eyes.

Our eyes take in light through the pupils, which passes through the lens, and focuses on the retina. This travels as an electrical impulse to the brain through the optic nerve which forms the image in our brain.

All of that happens on a physical level when you watch a movie, but your eyes need to express something. Like fear or surprise or sadness with a tear trickling down your cheek.

So, if a movie has “eyes” in the title, it may give you an eye-opening, eye-shuddering, or eye-can’t-believe-it experience. Or you might just shut your eyes and wait for the lights to come back on in the theater.

What are Sports Vision Skills?

What are Sports Vision Skills?

If you think that playing sports only involves running, throwing, tackling, and jumping, then you are missing other key skills every athlete must develop.

Sports vision skills are an integral part of every game. The eyes gather over 60% of information that is sent to the muscular and skeletal systems. Specific visual abilities affect sports performance because they directly impact motor skills. The great news is that just like physical exercise strengthens the body, visual skills can be improved with training.

Keep Your Eyes on the Ball (Maybe Not)

Every coach has said that and every player has tried to do it but focusing on a fast-moving object places a great demand on vision. A baseball hit into right field might seem like a blur but players can improve this visual ability by understanding how focusing works in a sports situation.


Humans can only focus both eyes on an object within a relatively small space. To get a look at what this means, try the Thumb Rule. Hold your arm straight out with your thumb pointing vertically. The width of your thumb in this position gives you an idea of the size of your visual focus. Now, before you get discouraged and think you will never be able to track a tennis ball or softball that is lobbed your way, be prepared to learn a focusing trick.

While it is difficult for both eyes to focus on a ball that is moving, you can concentrate your vision peripherally. Motion is more easily detected in your peripheral vision field. And the quicker you react to the motion in sports, the better able you will be able to play.

So, instead of intensely focusing on the ball, look to the midpoint. In basketball, for instance, this can mean looking at the area between the ball and the person you are defending. The movement of either the ball or the other player will be detected more quickly and you will be in a better place visually to make the right move.

What’s Your Eye D?

Of course, you all have ID, but Eye D refers to your dominant eye. If you know which eye it is, you can improve the way you play certain sports. That’s because the dominant eye processes and sends information to the brain just a little bit faster and more accurately than the other eye.

Let’s take a quick test. Extend both arms straight out from your body, at about shoulder height. With your thumbs and index fingers, form a small triangle. Pick an object in the distance and center it in the triangle. Close one eye at a time and look at the object. The eye that sees the object centered in the triangle is your dominant eye.

Now, take this information to the playing field. If you are a golfer, line up your next shot so that your dominant eye has a clear view of the ball and the hole. Tilt your head to give that eye an unobstructed look at the path the ball needs to travel.

While a physically fit body is important in sports, remember the role of your eyes. Without their ability to focus and process visual information, athletes would literally be at a loss. Get regular vision exams to keep your eyes at their best. And remember, it’s not only about winning; it’s also about being a better and healthier you.

What's Your Eyes' Age?

eat to protect your eyes - Smart Vision Labs

What’s Your Eyes’ Age?

Hold off on ordering yet another wrinkle cream because it might be your eyes giving your age away. Some things you’re probably doing every day are actually bad habits that can make your eyes seem older.

There are three main things your eyes react to which create an aging appearance: your health, irritation, and physical damage. These problems can build on each other which emphasize how important your overall health is.

What’s Your Beauty Eye-Q?

Is part of your beauty regimen eating well and drinking enough water? Your eyes benefit from a healthy diet and good hydration, inside and out. Dark leafy greens, citrus fruits, almonds, and eggs all contain key nutrients your eyes need to be functioning optimally. Those things could all even be part of a nice breakfast. When your eyes are working at their best, they’re not straining and creating redness and irritation.

Did you remember to pour a glass of water with your breakfast? You’ve noticed your eyes seem dry after spending a few hours working on a computer for work or after studying for a big exam at school. But one other way you might find yourself rubbing your dry eyes is if you are dehydrated. Stopping work to drink a glass of water gives your eyes a break by allowing them to focus on something else while you rehydrate them. This is especially true if you’ve been doing something that dehydrates your body, say, like drinking a few cups of coffee to stay awake while working.

Beauty Rest

It isn’t called ‘beauty rest’ for nothing. Nothing completes the “I was up all night” ensemble like puffy eyelids above your red eyes and dark circles below them. When you don’t get enough sleep, your blood vessels dilate and become visible through the thin skin under your eyes. ‘Bags’ below your eyes, as well as puffy eyelids, are caused by fluid retention. Both of these can usually be fixed and prevented by making sure you’re getting a good rest at night.

When your eyes are tired, do you rub the lids to make them feel better? That is definitely a bad habit. Tugging on the delicate eye skin creates lines and wrinkles that make you appear older. While some creasing and things like crow’s feet are a normal part of aging, breaking the habit of touching your eyes will keep any extra lines from showing up.

Just Hide It?

protect your eyes by wearing sunglasses and filter out the harmful UV raysYou have places to be and things like ‘sleep’ and ‘healthy breakfast’ are not on the to-do list. Your quick fix could be wearing some big designer sunglasses, like the kind that seem to cover half of your face.

Actually, this one is a good idea. Yes, the sunglasses will hide your red eyes and dark circles but they will also protect your skin from sun damage. Since this pair protects against 100 percent of UVA and UVB rays (or else you wouldn’t have bought them), their large lenses block the harmful rays from reaching your skin.

So put your shades on for now. Try to remember to get a good night’s rest when you finish your busy day. It turns out, keeping your eyes looking young and keeping them healthy are the same thing.

Do Eye Exercises Really Improve Vision?

Eye Fitness or Fallacy?

“Throw away your glasses! Improve vision naturally!”

“Do eye exercises really improve vision?”

There are two camps regarding eye exercises: why aren’t you doing them and why are you doing them? The kind of health blog you follow will determine which stance you’re familiar with.

Aid or Crutch?

The first group says visual aids, like prescription glasses and contact lenses, are a crutch for your eyes. They claim you can reduce or even eliminate your need for vision correction by following a regimen of eye exercises.

The idea behind this is that most people are born with good eyesight but around 70 percent of Americans have vision problems. Therefore, most of these issues are acquired through regular life events. If you did something to create them, they can also be undone through training the eye muscles. For this reason, eye exercises tend to focus on reversing myopia, or nearsightedness.

Does it Make Sense?

do-eye-exercises-workThat kind of makes sense though, right? If your arms are weak, you get a gym membership and some barbells, and gradually increase the weights until your muscles are strong.

The problem here is that, yes, you can make muscles stronger through working out, but your eyes aren’t muscles; they are controlled by them. Each eye has six muscles on the outside which control your line of sight and one inside which moves your focus in or out. This last one, called the ciliary muscle, is what eye exercises for myopia are usually targeting. The exercises suggested are really getting you to relax this muscle. This is based on the idea that if myopia is acquired through strain and tension of the ciliary muscle, relaxing will undo it.

But vision problems like nearsightedness are refractive errors. These happen when light doesn’t reach the correct part on the inside of the eye (the retina) due to the eyeball itself being the wrong shape. Exercising the muscles in and around the eye can’t really do anything for these problems. In myopia, the eye shape is too long for the focusing muscle, regardless of how relaxed it is.

Are Eye Exercises Safe?

Depending if your stance on eye exercises is favorable or not, you might be surprised to learn these workouts are safe to do. (Just don’t drive or do anything important with your glasses off to test out any of these exercise theories!) The upside of not having a positive effect on vision is that they also don’t cause negative ones. It doesn’t hurt at all to sit on the floor with your hands over your eyes imagining being enveloped in pure darkness. Relaxation is good; just don’t expect better vision when you finally open your eyes.

Do keep in mind what you’re “learning” though. Picturing darkness just relaxes yourself, which actually might show you temporary improvement if you are suffering from eye strain, but not myopia. Rolling your eyes (like you might be doing right now at this article?) doesn’t use the interior focusing muscle at all. Reading numbers off a calendar without your glasses or contacts is just teaching you to read through your blurry vision, not to improve it.

Oh, there’s also no scientific studies or evidence to support these claims.

It might be a good idea to keep your glasses a little while longer and to have regular vision exams. They actually work, which is more that can be said for some of these eye workouts.

Why Vision Is the Most Important Sense - Learn why at Smart Vision Labs

Why Vision Is the Most Important Sense Organ

Out of all the five senses, your vision seems the most important. Humans are fairly unique in their reliance on sight as the dominant sense and this is reflected in how complicated our eyes are relative to other creatures.

Many animals gain most of their information about the environment through their sense of smell. Your dog’s nose tells him much more about his world and who is in it than his eyes (which can actually see some color). In contrast, you can’t smell all the wildlife that visited your yard but you could see them in vivid color.

How the Eye ‘Sees’

Why are human eyes so much more capable? Basically, it is because they have more components which collect information.

When you see something, like your pet dog, your eyes don’t actually see him, your brain does. At the start of what will become your vision, light enters your eyes. Your pupil, the black center of your eye, and the iris, the colored ring around it, work together to widen or constrict the pupils so the appropriate amount of light enters the eye.

The incoming light travels through two layers: the cornea and the lens. The cornea at the front of your eye, and the lens, located right behind your pupil, work in tandem to focus the light ray onto a specific spot at the back of your eye, on the retina.

At the retina is where the raw sight data your eyes collected from light begins to be translated into useful visual information. The light focused on the retina triggers photoreceptors which are used to create visual cues. The retina contains two types of photoreceptors: rods and cones. There are about 120 million rods and up to 7 million cones. Rods are more sensitive than cones but cannot detect color, which the cones can.

Humans have 3 types of cones which perceive the presence of red, green, and blue. These combine in different levels to create the full range of color we see. In case you’re wondering, your dog only has 2 of these, yellow and blue, which means his vision is closer to a human with red-green colorblindness than just black and white.

Now that information about the item and its color are collected, the rest of the work is left to the brain. This new data is sent along the optic nerve to the brain, which is what tells us what we are looking at. Along with what we are seeing, the brain sends information about the context: what does looking at this mean, is it dangerous, or other related memories.

Also your eyes and brain are constantly doing all of this. All in a tiny fraction of a second.

The Eye as a Sense Organ

The way sight works is why it is one of the five senses. The eyes are the physical portal through which data from your environment is collected and sent to your brain for processing. The brain plays its part by converting the light that went into your eyes into usable information – how far away, how bright, what color.

So if you were to look at your dog, you would see that, yes, it is a dog but also what breed he is and that he is your pet and would probably like his ears scratched.

Humans are built to collect information with their eyes and even reduced vision quality creates a negative effect. A regular vision test is a small investment for something that has such a huge impact on our lives.

Our eyes aren’t just performing a task, they are the portal through which our brain can tell us about our world, learn new things, and make wonderful memories. All of which are reasons why vision is such an important thing to take care of.

Blue light and your eyes - Smart Vision Labs

Seeing Blue?

You have probably heard that spending long hours using the computer can cause eye strain but do you know why? Learning about the connection between computer monitors and digital eye strain will also clue you in on how to reduce the uncomfortable side effects.

Why Does Using a Computer Hurt Your Eyes?

Initially, you might think it has to do with the light being too bright for your eyes. But this is only part of the answer. It is indeed the light from your monitor that causes eye strain but it is a certain type.

Your computer screen emits blue light and that specifically is what your eyes are reacting to. Blue light is also called high energy visible light, or HEV light. For reference, it is only one stage lower in energy than ultraviolet (UV) light. Blue light is the highest energy light that we can also see, therefore the name HEV.

Digital eye strain occurs because your eye isn’t very good at blocking light in the blue part of the spectrum. While only a tiny bit (less than one percent) of UV light actually reaches the sensitive retina, nearly all blue light does. (Note that sunglasses are necessary to block 100 percent of UV rays because even the small amount that gets through is very damaging.) Blue light tires your eyes out because it is both high energy and is easily scattered. It doesn’t focus as well the rest of the light spectrum which causes the eye strain you feel after staring at your computer screen.

How Do You Avoid Blue Light?

Well, you can’t, not entirely. While blue light is associated with digital devices like computers and smartphones, the sun itself is a natural source of this light. The white light from the sun is made from the combination of all the colors which compose the light spectrum, blue included. The sun is the primary source of exposure to HEV light.

Additionally, you actually don’t want to avoid all of it. Keep in mind that sunlight contains blue light and exposure to the sun, so your body can manufacture vitamin D, is essential to good physical and mental health. The presence of blue light also helps your body maintain its natural sleep/wake cycle, called circadian rhythm.

Of course, there are many man-made sources which emit blue light as well. But, unlike with sunlight, we can limit our exposure to these. Smartphones, tablets, computer monitors and television screens are indoor sources of blue light. Lamps with fluorescent or LED bulbs also shine using blue light. While these items all give off way less HEV light than the sun, we also spend quite a bit of time exposed to them, which increases their negative effects.

Solutions to Blue Light Exposure

Just as people have created the issue of digital eye strain from blue light with the prevalence of computers, they have also invented solutions so we can continue using our electronics in comfort. Of course, taking frequent breaks to rest your eyes is always helpful, regardless if you are using a phone or computer.

For your eyes, both anti-reflective lens coatings and special computer glasses are available. If you already wear prescription glasses, opting for an anti-reflective coating means you don’t have to do anything extra to protect yourself, other than make sure your glasses are actually on while using your device. If you prefer contact lenses or don’t need any vision correction, yellow tinted computer glasses are worth considering.

You could also block the blue light on the device itself. There are screen protectors available which filter it out while they keep scratches off your device. Some devices also have a setting built in to manage blue light.

So to keep your eyes from seeing red, limit the amount of blue that goes into them.
