The curvature of the lens may change as well along with the wearing out of the ciliary muscles. These changes may also collectively lead to the development of presbyopia.

Experiencing Presbyopia

The condition affects just about everyone at a certain age. Symptoms are commonly noticed between the ages of 40 to 50. These may manifest as difficulty in reading fine print under conditions of poor lighting or experiencing eyestrain after prolonged periods of reading. The symptoms of presbyopia can often be nullified by conditions of bright sunlight as the iris closes to a very small size, achieving a greater depth of focus without the use of the natural focusing mechanism of the eye.

Treating the Condition

Nevertheless the condition is not usually curable. It can however be improved by using eyeglasses or contact lenses. Depending on the existence of other refractory conditions, multifocal lenses may be of value. With worsening focus, the prescription lenses will need to be adapted accordingly. Bifocals and multifocals may not be the right solution for everyone. They can cause straight lines to appear bent and result in a feeling of dizziness depending on use. Using multiple prescription glasses may be an alternative solution to relying on multifocals. This option however, can be inconvenient and even distressing if a specific pair of prescription glasses is mistaken for another or misplaced.

Monovision may be used to get around wearing bifocals and reading glasses. This involves using an oppositely correcting contact lens for each eye so that one eye is able to see near while the other sees far. This can however, interfere with the perception of depth.
