Your eye is made up of a lot of parts, including the cornea (the outside covering of the eye), the pupil (which lets in light), and the lens, which focuses that light onto the retina (the back of the eye) so that your brain can interpret the image that you see.
The lens is one of the most important parts of the eye, and if you’re wearing glasses or contact lenses right now, it’s because the lens of your eye is misshapen in some way, making it hard for your eye to properly focus the light coming in.
These are the kinds of problems that ophthalmologists like Dr. Patricia Bath work to fix so that people can see better. Test your vision with the activities below!
