A cataract is a clouding of the lens of the eye, which should normally be clear. Cataracts are usually painless and develop slowly, causing a gradual worsening of vision. Cataracts will affect the vision of most individuals by the time they are at the age of 75, but risk factors speeding up their development include diabetes, too much exposure to UV light (sunlight), smoking, and eye injury.

Dr. Ilan Cohen answered:

What causes cataracts?

TIme

Smoking
Most cataracts are caused by age related degeneration in the proteins in the lens of the eye. This degeneration causes the lens to lose its transparency. Cataract formation can be accelerated by trauma, steroids and other medications, diabetes, smoking, excessive ultraviolet light exposure and some other things. See your eye doctor if you suspect cataracts.

How long do cataracts last?

Until treated

Cataract
Most cataract occur later in life and gradually progress if untreated. Some congenital and traumatic cataracts of earlier life are static and may last a lifetime without change. Given the success of modern cataract surgical removal, you should have your ophthalmologist evaluate your cataract for treatment potential. Not something an optometrist can do.
