Causes And Risk Factors For Cataracts
Specifically, cataracts refer to a clouding of the eye's lens, which is situated behind the pupil and the iris. There are several different types of cataracts, but all of them result in the same symptoms, such as difficulty focusing and fogginess or blurriness in parts of the eye (or both eyes) that do not go away over time. Cataracts can occur to anybody at any age, but it is worth noting that they're most common in people over the age of 40. It is also believed that prolonged sun exposure (without protection from UV-blocking sunglasses) can increase a person's risk of developing cataracts.
Some other potential risk factors for cataracts include:
● family history of the condition● smoking● obesity● diabetes or hypertension
