- Slide: 1
- Cornea ->
- ^ Retina
- This is your eye! Light passes through and is refracted by your cornea. For an eye with perfect vision, the rays of light converge on the retina, which is where the image is formed. Of course, there are many factors as to why this might not occur. The natural shape of your eyeball, the curvature of your retina, and cataracts can disrupt the convergence of the light rays, causing unfocused vision.
- Slide: 2
- Since many of those happen naturally, how do you correct my vision? Like with my contacts, how do they fix myopia?
- Great question! With myopia, also known as nearsightedness, the rays converge before hitting your retina, forming the image in front of your retina. To fix this, we prescribe diverging contacts. They allow the rays of light to converge later, which forms the image on your retina with the correct prescription! For people with farsightedness, their images form behind the retina, so we prescribe converging lenses to move convergence forward to the retina.
- Slide: 3
- Now, cataracts are a bit different. It occurs when proteins in your natural lens break down and cloud vision. When light passes through your lens, it is bent and scattered, causing the light to haphazardly hit the retina without true convergence, creating blurry vision. The good news is that corrective surgery for your cataracts can also correct your myopia. This means you wouldn't have to deal with glasses or contacts anymore!
- Really...? That does sound very appealing...
