4. Difficulty in seeing colors
This disease can actually give you a form of colorblindness. The reason for this is the same as the blurriness that we already discussed.
The macula, the center part of your retina, can become inflamed, as can the nerve fibers located there, causing blurry vision, but also causing some people to have a hard time differentiating between colors.
Plus, some people report having an extremely difficult time seeing at night.
