What is a refraction? explains it this way: Refraction is the part of an eye or vision exam in which the eye doctor determines your need for prescription glasses. He or she refracts your vision by using a phoropter, a device that contains hundreds of combinations of lenses, to determine any possible refractive error such as nearsightedness, farsightedness, astigmatism, or presbyopia. Several methods may be used for refraction, but most people are familiar with the type of refraction in which the doctor asks, "Which lens is clearer or better -- lens one or lens two, or do they appear about the same?"


Refractions are used to for two primary purposes: 1. to determine your eyeglass prescription; or 2. to determine your "best-corrected" vision, which is frequently necessary to evaluate the extent of medical eye conditions or the severity of a cataract.


Will Medicare pay for my glasses?

There is only one instance in which Medicare pays for eyeglasses, and that is a one time event, after cataract surgery.


What is the difference between an Ophthalmologist, Optometrist & Optician?

Ophthalmologists are medical doctors, who have completed a bachelor's degree before completing four years of medical school, then a 3 year internship in which they specialize in medical and surgical eye care. Optometrists are doctors of optometry who complete a bachelor's degree and then four years of specialized training in eye care. Optometrists provide routine eye care, and also evaluate and treat some medical eye condition, but do not perform surgery. Opticians fit eyeglasses after completing either 2 years of college or an extended internship. At Twin Tiers Eye Care, the "three O's" as they are sometimes referred to, work together to offer comprehensive eye care services.
