For my perception project, I decided to work on a condition called astigmatism. People with astigmatism have irregularly shaped cornea or lens. This causes the cornea or lens to not allow light to pass through correctly, often distorting and scattering the light that passes through the eye so that it does not focus properly on the retina. While the effects of myopia and astigmatism sound similar, astigmatism can cause distortion in shapes and forms, and the blurriness is not affected by distance. Astigmatism can be present at birth, or result from an eye injury. It is often corrected with special glasses or contact lens, though surgery is also an option.
