Presbyopia

Presbyopia affects everyone and usually begins to affect vision around age 40. Rays of light from near objects such as a printed page are divergent in nature and will come to a focus behind the retina. In order for this light to focus on the retina, accommodation occurs. During accommodation, the ciliary muscle contracts. This contraction results in an increase in the curvature of the lens. Refocusing light back onto the retina. The aging process causes a gradual hardening of your lens, causing its inability to change shape. From age 40 onward, close work gradually becomes more difficult.

The newest option for correcting presbyopia is multi-focal contact lenses. Certain types of these lenses are designed to correct your vision for both near and far, while other designs are able to correct your vision for near, far, and all distances in between. To get started with multi-focal contact lenses, your eye-care professional may ask you a number of questions to help determine the best lens design for your lifestyle. While multi-focal contact lenses may require an adaptation period so that your eyes can get used to them, ultimately these lenses can greatly enhance your quality of life. Other solutions include glasses.
