Rarely, cataracts can present at birth or in early childhood as a result of hereditary enzyme defects, and severe trauma to the eye, eye surgery, or intraocular inflammation can also cause cataracts to occur earlier in life.
Cataracts can cause significant changes in vision. Cataracts occur not just in older adults, but in younger people too. Injury, certain medications, and genetic conditions can result in cataracts, even in the very young. It should be noted that not all vision changes are the result of cataract. Several of the above symptoms can be signs of very serious and life-threatening conditions. See an eye doctor to discuss your vision changes and any other symptoms you may be experiencing.
