This is a naturally occurring vision disorder, that develops as you age. It affects your ability of being able to view objects up close. Symptoms typically begin after the age of 40, where you’ll start to notice that your eyes are unable to focus on objects with fine print on them, unless they are held from a distance. Many of those with Presbyopia experience eyestrain and headaches when performing close range tasks, for example, working on the computer or reading a book.
The disorder is an age-related process which involves the gradual thickening of the crystalline lens, causing it to lose flexibility overtime. This in turn causes the light entering the eye to focus beyond the retina, resulting in poor vision for objects that are close up. The impairment can be corrected using; single vision reading glasses; bifocal lenses; varifocals; and multifocal contact lenses or monovision lenses.
