Presbyopia: Presbyopia is the gradual loss of your eye's ability to focus on nearby objects. It's a natural, often annoying part of aging. Presbyopia usually becomes noticeable in your early to mid-40s and continues to worsen until around age 65.
You may become aware of presbyopia when you start holding books and newspapers at arm's length to be able to read them. A basic eye exam can confirm presbyopia.
 
A simple solution for this is READING GLASSES. Recommended to choose according to your age.
You may also be able to determine which strength of reading glasses you need by consulting a ‘power by age table’
