One theory suggests that cyanopsia may develop due to the sudden unmasking of blue light sensitivity after cataract surgery, as the brain adjusts to the removal of the natural lens. For medication-induced cyanopsia, the inhibition of PDE6 is believed to temporarily disrupt normal photoreceptor function, emphasizing blue light in visual perception.
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'.
The human eye is an organ which reacts to light for several purposes. As a conscious sense organ, the eye allows vision. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth. The human eye can distinguish about 10 million colors. [3]
Early symptoms of cataract may be improved by wearing appropriate glasses; if this does not help, cataract surgery is the only effective treatment. [4] Surgery with implants generally results in better vision and an improved quality of life: however, the procedure is not readily available in many countries. [4] [11] [12] [13]
The use of over-the-counter artificial-tear solutions can reduce the effects of dry eye in CVS. Prior to using artificial tear solutions, it is necessary to check if dry eye is the actual cause of the problem (measured by a tear meniscus test) [7] or whether there are no actual symptoms of dry eye at all. Dry eyes because of CVS can also be ...

A Cochrane Review found little evidence of important differences between blue‐light filtering and non‐blue‐light filtering lenses for protecting the macula (back of the eye) after cataract surgery. [27] This may have been due to studies being too small and too short‐term to provide reliable results.
In the weeks leading up to Monday’s complete solar eclipse, eye doctors have repeated the same advice: Don’t look at the eclipse without proper eye protection.
