A lensmeter or lensometer, also known as a focimeter, is an ophthalmic instrument. It is mainly used by optometrists and opticians to verify the correct prescription in a pair of eyeglasses, to properly orient and mark uncut lenses, and to confirm the correct mounting of lenses in spectacle frames. Lensmeters can also verify the power of contact lenses, if a special lens support is used.
The parameters appraised by a lensmeter are the values specified by an ophthalmologist or optometrist on the patient's prescription: sphere, cylinder, axis, add, and in some cases, prism. The lensmeter is also used to check the accuracy of progressive lenses, and is often capable of marking the lens center and various other measurements critical to proper performance of the lens. It may also be...

This test is for determining the farsightedness, astigmatism, and presbyopia and nearsightedness level of the patient via a thorough eye exam in Toronto. Barometers and auto refactors are other tools used by the optometrist to diagnose different problems related to the eye of the patient. These are for automatic estimation of eyeglass prescription. Auto refactors work as manual refraction determining the power of the lenses for accurate focusing of light on the retina.

Laser eye surgery is a remarkable medical advance that has helped millions of people improve their vision, and free themselves from having to rely on glasses or contact lenses. So in this article we present a number of questions to ask yourself to help you decide whether LASIK is right for you. LASIK is remarkably effective in treating the following vision problems – farsightedness, nearsightedness, and astigmatism. It is generally not effective at treating presbyopia (age-related near vision problems). This may sound like an odd question when considering a surgical procedure on your eyes, but it's one of the most important questions to ask yourself. You need to be in good general health so that your autoimmune system can heal from the surgery quickly, and you need to be free from eye diseases and from autoimmune diseases.
