Is it getting harder and harder to read the fine print? Chances are your eyes might be losing their ability to focus. This is actually a common problem among adults. This condition, where the eyes lose the ability to see near is called presbyopia.
In presbyopia, the elasticity of the lens in the eyes is reduced. The lens is located inside of the eye and is supported by intricate muscles to help it remain flexible. As the eye ages both the lens and the muscles supporting it become less flexible. This inflexibility makes it difficult for the eyes to focus.
Being unable to read the small print is generally the first sign of presbyopia. For others it may be a sewing project or reading small type on a computer. Any activity that requires near vision is most likely difficult when you have presbyopia.
Presbyopia typically begins in the mid 60's, but some people notice symptoms in their 40's. As they eye ages, the symptoms will increase. Adults who are nearsighted, (unable to see clear at a distance) can also develop the condition.
For some, dealing with presbyopia is a simple lifestyle change. Reading larger print or with more light can help inflexible lens focus better and make it easier to read. Many people find that holding items at a distance may improve vision, since presbyopia affects near vision. The majority of people use reading glasses when needing to see up close or use magnifiers. Adults with glasses for nearsightedness may switch to bifocal or progressive lens to improve their near vision.
There are some surgical options for presbyopia. Although LASIK does not correct the lens, using it to correct near sightedness in one eye only (monovision) is considered a treatment for some patients with presbyopia. Patients can also have lens replacement surgery, which replaces inflexible lens with an artificial equivalent. Also, many patients who receive cataract surgery often gain some relief from presbyopia as a result.
Presbyopia should be taken seriously. Ignoring it can lead to the development of eyestrain. Eyestrain can cause painful headaches and fatigue that are only relived by rest. Also, overworking the eyes can cause the symptoms to increase much faster.
If it is becoming more difficult to see small letters when you are reading, chances are you may be developing presbyopia. An ophthalmologist is able to diagnose and find the most appropriate solution for seeing the little things in front of you.
