Agesightedness is a natural part of the aging process that affects everyone. Ideally, the lens of the eye needs to change its length or shape to focus on smaller objects, or objects that get closer or farther away. This is called the elasticity of the lens. This elasticity is slowly lost as people age. The result is a slow decrease in the ability of the eye to focus on nearby objects.
Agesightedness is a condition in which the lens of the eye loses its ability to focus, making it difficult to see objects up close. The symptoms include decreased focusing ability for near objects, eyestrain and headaches. People usually notice the condition at around age 45, when they over time realize that they need to hold reading materials further away in order to focus on them. However, it will still be possible to read with the help of the right prescription. People who do not need glasses for distance vision may only need half glasses or reading glasses.
There is no cure for agesightedness, but it can be corrected with glasses or contact lenses. In some cases, adding bifocals to an existing lens prescription is enough. As the ability to focus up close worsens, the bifocal prescription needs to be changed. The health care provider will perform a general eye examination, to determine a prescription for glasses or contact lenses. The tests will include; examination of the retina, muscle integrity test, a refraction test, slit-lamp test, and visual acuity
