Autorefractor Accuracy in Children

As nearsightedness spreads to younger generations, autorefractors are now at the forefront of detecting early signs of myopia.



As technology increasingly becomes a part of our everyday lives, myopia (nearsightedness) is on the rise, particularly in pediatric populations. According to the American Optometrists Association, 1 in 4 parents have reported that their child has the condition. Now more than ever, it’s important to check on your child’s vision health. 

Nearsightedness affects nearly 2.6 billion people worldwide and occurs when the eye becomes deformed. While its effects may be hard to reverse, myopia can be easily detected by getting your eyes checked for refraction errors. Lengthy eye exams can be difficult for children to sit through, but autorefractors (AR) now offer an easy solution. With autorefractors, we can now detect refraction errors in children in as short as five minutes.

graph_pediatricsA recent 2020 literature review conducted by Lorri Wilson M.D. and others evaluated over 15 studies that tested the accuracy of autorefractor measurements as compared to more traditional retinoscopy. The study investigated findings in both cycloplegic (eyes paralyzed for the measurement) and noncycloplegic conditions for children. 

In noncycloplegic environments, only SVOne and Grand Seiko WAM were able to produce a mean difference in spherical equivalent or sphere of less than 0.25 diopters (D) from cycloplegic retinoscopy results. These devices are able to so closely reproduce these results due to their open channel design during refraction. This design allows them to then reduce accommodation errors. 

Autorefractors are a quick and accurate solution to the growing demand for eye checkups for children. With this device, we’re now able reproduce clinically accurate measurements in short amounts of time. This technology will allow us to widely test large pediatric populations in anywhere from schools to remote rural areas.

Adapting Your Store's Vision Exams for COVID-19

How you can change your store model to safely administer vision exams during COVID-19

Learn how to adapt your store model to keep your staff and customers safe. We spoke with Lumos Optical to hear about the steps they’re taking to safely provide vision exams. 

Many small businesses around the country have been struggling with reopening their stores safely and avoiding overcrowded their shops. For glasses stores and optometrist practices, this can be especially hard to navigate because of up close vision exams and glasses frames tried on by many different customers.

Lumos Optical had their grand opening on May 1st when the country was seeing COVID-19 cases back on the rise. Despite their unconventional opening, vision exams have become their most popular service. They’ve created a store model that allows them to keep selling while keeping their staff and customers safe. 

Safety Practices – Introducing the Appointment Based Model

To help handle their popularity, Lumos has been taking extra steps to ensure they’re staying safe. In addition to requiring masks and wiping down all glasses between use, they’ve decided to introduce an appointment-based model to their store

“We’ve had to adapt our business model because of COVID,” Lumos said. “We are appointment-based only instead of being open to the public. This allows us to clean and sanitize between each visit.”

Requiring appointments can help reduce crowded stores and give customers the peace of mind when shopping in person.

Lumos Optical and Smart Vision Labs

The store owners chose to integrate the SVOne into their business model early on. “We knew from the beginning that we wanted to integrate Smart Vision Labs,” they said. With Smart Vision Exams, Lumos Optical has seen increases in sales and become a one-stop glasses destination.

For many doctor’s offices, COVID-19 has created an appointment backlog and patients are less likely want in-person exams. The SVOne allows stores to help customers to renew prescriptions quickly and safely. “We didn’t know how popular the Smart Vision Exam was going to be. During our first month, we realized that the majority of appointments made were for vision exams. We saw an overwhelming number of appointments for the vision exam for people coming out of quarantine.”

The Socially Distanced Vision Exam

Introducing the Socially Distanced Vision Exam

Smart Vision Exams are an easy addition to any glasses store to make your shop a one-stop destination. We spoke with Salem Opticals in North Carolina to get tips on operating your business during COVID-19 and how Smart Vision Exams have been helping them to drive up business and increase vision exams.

COVID-19 has been hitting small businesses across the country, with an average of 31.4% of business owners saying it will be six months before things go back to normal. But some Smart Vision users have been able to make lemonade out of lemons and have been seeing their number of vision exams go up since reopening. 

For Salem Opticals in North Carolina, they’ve seen a huge surge in exams since reopening. “Doctors have backlogs for anywhere up to four months now because of COVID,” the store owner said. “With the SVOne, we’ve been able to take in more customers with the quick service. Before we were only doing 1-2 vision exams per day. Now, we have anywhere between 8-12.”

Working long days from home can mean staring at the computer screen for up to eight hours everyday. Glasses wearers looking to renew their prescriptions find themselves waiting anywhere from a month upwards to schedule an appointment. With the SVOne, your store can become a one-stop destination where customers can get their prescription renewed and snag a new pair of glasses—all in one day! 

Safety Tips for Your Store

Salem Opticals also shared some of their tips for operating safely during the pandemic:

  1. Make sure to follow all CDC guidelines and local/state regulations.
  2. Follow social distancing recommendations and ask that all your customers and staff wear masks indoors!
  3. Disinfect all equipment (including the SVOne!) as well as all frames that customers try on and touch to keep down the chances of the spread of infection!

Integrate the SVOne today and start administering Smart Vision Exams in your store. “People are open and responsive to Smart Vision exams because they’re short and not in your face. Customers always come out happy.”

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.

Exploring Mobile Vision Care

Good Hope Ministries distributes over 10,000 pairs of reading and prescription glasses a year in Malawi Africa using their SVOne device. The Good Hope team travels to about 90-100 villages each year, in 2019 they helped about 15-60 patients in each rural village.

Good Hope has received a second SVOne will now be able to open a walk-in eye clinic at their head office in February. They are expected to see at least 20-30 people a day in their new office.

All glasses are given free of charge in the villages and at the home base clinic, they charge $1.00 for a pair of glasses.

They are also able to give away 40-60 pairs of reading glasses in each village. Good Hope also visits four prisons in Malawi and distributes glasses there. They have tried other autorefractors, but now only use the SVOne. The SVOne works very well for the mobile vision care they provide.


The Future of Optical Retail is Convenience

Customer Spotlight: Modern Day OptX

What technology do you use in your optical store? 

I’ve used Smart Vision for three years.  My newest store technology creates an accurate 3D scan of your face; Capturing your biometric measurements. Customers can move and see themselves in a custom pair of glasses that fit them perfectly. They can see exactly how the frame looks from different angles. You can design 8 billion pairs of glasses.

Why do you work with Smart Vision Labs? 

The Smart Vision Exam works with people’s schedules. One thing I hate is making an appointment, the Doctor’s office, for example, and I’m waiting for an hour or two. I have been not double booked but triple booked for my appointment.

I want to be on people’s schedules. My availability for an eye exam is from 11:30-7. When you’re available, get an eye exam. The exam takes 5-10 minutes; it’s inexpensive, and 99% of the time right. We can get it right for our customers. I work with the fast-pace New Yorkers, and I’m on their schedule.

What do you want to accomplish with your business? 

I want to offer high-end products at the lowest price. By investing in technology, I don’t have as many overhead costs. I can give my customers a convenient high-end product at a lower price.
