How does the eye work?
The human eye (illustrated above) works by allowing light to travel through the clear cornea and enter the pupil. The lens then focuses the light onto the retina which converts the light into an image, which our brain can process.
What are some of the common vision problems?
- Nearsightedness - Myopia - The eye focuses light in front of the retina. Objects farther away are blurred while things up close remain clear.
- Farsightedness - Hyperopia - The eye focuses light behind the retina. Objects can be blurred at near and far depending on the amount of farsightedness and the amount of focusing power of the eye.
- Astigmatism - The eye is irregularly shaped causing blurring of vision at all distances. People will often squint to clear their vision.
- Presbyopia - The loss of focusing power with age which causes blurred vision at near. Farsighted individuals will often also begin to have problems with their distance vision
All the above conditions can be corrected with glasses and contact lenses. Laser vision correction, LASIK, can correct nearsightedness, farsightedness, and astigmatism. Currently there are several surgical options being developed for the correction of presbyopia.
