What is Second sight phenomenon?
“Second sight” refers to a temporary change in vision during early cataract development. Before vision deteriorates, vision, especially close-up reading vision, improves significantly. Some patients report very clear near vision without the use of reading glasses.

While prescription glasses cannot directly treat or cure cataracts, the right prescription lenses can help to correct blurry vision and other vision problems caused by cataracts. For example, many people who have cataracts will experience a change in their corrective vision prescription.
What causes cataracts to grow quickly?
Trauma-related cataracts are typically the most fast-growing type of cataracts. Radiation: Radiation-related cataracts, sometimes listed under trauma-related cataracts, occur after the lens has been exposed to radiation. Exposure to high levels of radiation can result in clouded vision in as little as two years.

What are cataracts and how do they affect vision?
Cataracts are the leading cause of blindness among people older than 55. Most older people have some degree of lens clouding, which is a normal part of aging. A cataract is generally painless.
