Presbyopia

Do you need reading glasses? Chances are, you have presbyopia, a disorder that causes a decrease in the eye's ability to focus, typically as a result of the natural aging process that everyone eventually experiences. The first signs usually appear in the early to mid 40s, which is why so many middle age people begin to need reading glasses or bifocals around this time.

While the exact cause of presbyopia is still under research, the common theory is that the muscle fibers around the eye's natural lens stiffen and lose their elasticity, decreasing the eye's ability to change the lens' shape. As our natural lens becomes less flexible, we are less able to focus on close objects.

Treatment options are reading glasses, bifocals, trifocals, or bifocal contact lenses. You can also have mono vision LASIK/PRK where one eye is left nearsighted for reading and the other eye is left for distance vision. Artificial intraocular lenses (IOLs) to treat cataracts are becoming more advanced, with some designed specifically to treat presbyopia and cataracts simultaneously.
