 What is likely causing your vision to deteriorate is cataract formation. Cataracts occur when the lens of the eye becomes cloudy and blocks light from entering, which interferes with sharp, clear vision. A science-based cataract reversal eyedrop called CAN-C is changing lives of people with poor vision caused by cataract.
