The primary causes include post-cataract surgery, certain medications, and, less commonly, neurological or ophthalmological conditions. Post-cataract surgery is a common cause, as replacing the natural lens with a synthetic one increases exposure to blue light, leading to temporary blue-tinted vision. This effect usually resolves as the eye adapts.
Posterior capsular opacification, also known as after-cataract, is a condition in which months or years after successful cataract surgery, vision deteriorates or problems with glare and light scattering recur, usually due to thickening of the back or posterior capsule surrounding the implanted lens, so-called 'posterior lens capsule opacification'.

Researchers have recently developed a new drug that will ultimately shrink down and dissolve cataracts -- the leading cause of human blindness that affects tens of millions of people worldwide.

Photophobia is a symptom of excessive sensitivity to light which affects 5 to 20% of the population ...
