Blurry Vision and Why we Dot the "Eyes" - Smart Vision Labs

Did you ever wonder why we place a dot over the letter i?

It’s to make sure that this letter is seen. Otherwise, the letter i is just a small line in the midst of a word. It would be very easy to be overlooked.

But when you see a dot, you recognize the letter i.

The dot makes you see what you are supposed to see.

Your eyes work in a similar way.

When light rays enter your eyes, they travel through the pupil, or dot in your eyes. The light rays are then curved so that they focus on the retina, which is located in the back of the eye.

These rays of light are then transformed into electrical impulses that travel to the brain through the optic nerve. The brain ‘reads’ these impulses and creates an image that you see.

Having perfect vision is everyone’s wish, but sometimes, the eyes do not process the light rays correctly. In the case of nearsightedness, the light rays are focused in front of the retina rather than directly on the retina.

Farsightedness is just the opposite. The light rays focus behind the retina.

These are called refractive errors because the eyes are not bending, or refracting, the light rays correctly. Yet, these conditions can be easily addressed with the right prescription eyeglasses.

Fixing Blurry Vision

If you feel that you have blurry vision, whether you are looking at things close up or far away, a 5-minute vision exam may be just what you need.

Yes, in only 5 minutes, your vision will be checked. You will need to first answer a few simple questions about your eyes and your health. Then your eyes will be scanned using the same type of technology designed for LASIK procedures. Some photos of your eyes will be taken and then all of this data will be sent to a licensed eye doctor. After this information is reviewed, you will get an email, within 24 hours, explaining the results of this exam.

If you need corrective lenses, a prescription will be given to you.

The interesting thing about corrective lenses is that they are curved to make sure the light rays focus on the retina, like they are supposed to.

It’s almost like putting the dot on the letter i. The curve of the lenses is calculated to focus the light rays on the retina which will improve your vision and help you to see better.

The exact curvature of the lenses will be determined by the data generated from the 5-minute vision exam. For nearsightedness, concave lenses are used, while convex lenses are helpful in correcting farsightedness.

The good news is that refractive errors in vision can usually be addressed with the right prescriptive lenses. And the even better news is that a 5-minute vision exam can determine if you have a condition that can be improved with eyeglasses.

The dot on the i lets you see that letter better.

And a vision exam can let you see the rest of world more clearly.
