Presbyopia, otherwise known as the inability of the eye to make fine adjustments, is often mistaken as either myopia (nearsightedness) or hyperopia (farsightedness). Presbyopia is entirely different from being nearsighted or farsighted but may occur alongside those refractive errors.
It is important to note that presbyopia is not a disease but simply a part of the aging process. Normally, the eye has the natural ability to easily shift focus when looking at objects that are either far away or up close. This process is known as accommodation.
When you look at objects that are close to you, your eye muscles contract, which in turn flattens the lens. Once the lens has flattened, light rays are bent at an angle that makes it possible for you to see close objects clearly. On the other hand, your eye muscles relax when you’re looking at distant objects. Consequently, the lenses become outwardly curved and incoming lights rays are bent at an angle that allows for a clearer view of the distant images.
Presbyopia becomes noticeable once an individual hits the early to middle 40s, earlier in some people. The gradual inability of the eyes to focus is attributed to stiffening of the lens and weakening of the eye muscles.
Corrective glasses are the standard treatment of choice for presbyopia. Laser treatment may also help through a procedure referred to as monovision, where one eye is treated for near vision while the other one is corrected for far vision.
