Contact lenses "possible option for presbyopia"

Contact lenses "possible option for presbyopia"

Sufferers of the eye condition presbyopia have been offered a list of ways to correct their vision in the New York Times.

Camille Sweeney explained in the newspaper that options such as bifocal and multifocal contact lenses and monovision lenses are possibilities, as well as certain surgical procedures.

Presbyopia is believed to be caused when an eye"s lens becomes less flexible and is an age-related ailment.

As a person grows older, proteins within the lens and the fibres of the muscle around it alter and it becomes more rigid.

Ms Sweeney explained that bifocal and multifocal contact lenses can be used to correct the sight of sufferers of the condition.

Wearing a lens for seeing things far away in one eye and for close viewing in the other (monovision lenses) is another option.

There are also surgical procedures such as monovision and conductive keratoplasty.

Refractive lens exchange is another possibility, by which an artificial lens is placed in the eye to replace the natural one.
