is caused by a hardening of the lens of your eye, which occurs with aging. As your lens becomes less flexible, it can no longer change shape, and close-up images appear out of focus.

Presbyopia develops gradually, over years. You may first notice these signs and symptoms:

A tendency to hold reading material farther away to make the letters clearer, blurred vision at normal reading distance, eyestrain or headaches after reading or doing close work. Age is the greatest risk factor for presbyopia. Almost everyone experiences it after age 40 years

Premature presbyopia:

However, some people can develop presbyopia earlier than age 40 years, as a result of certain diseases or certain drugs. Premature presbyopia can be an indicator that you have a systemic disease you may not be aware of. Risk factors for premature presbyopia include:

Systemic diseases:

Certain diseases, such as diabetes, multiple sclerosis and cardiovascular diseases, can increase your risk of premature presbyopia.


Certain prescription and nonprescription drugs can affect the flexibility of your lens. They include antidepressants, antihistamines, diuretics and alcohol.
