I had cataract surgery 22yrs ago at age 38. my cataracts were the results of high doses, and of regular doseing of Prednisone for treatment of my asthma.
Cataracts produce a progressive, painless loss of vision. Their cause usually isn't known, Although they sometime result from exposure to X-RAYS(such as high-dose radiotherapy to the eye) or strong sunlight,inflammatory eye disease, certain drugs (such as in my case Corticosteroids) or complications of other disease such as Diabetes,They're more common in older people; babies can be born with cataracts(congenital cataracts)
