Did you know that many patients believe that the most important part of their glasses is the frame? Actually, the most important parts of your new glasses are the lenses. Our knowledgeable opticians will help you pick the lightest, thinnest lenses to help you see your best. When you visit our full service dispensary, be sure to ask about the latest lens technologies which can help with night driving, computer use, and glare and reflections from the sun.
The first decision when choosing your lenses is selecting the material for your new lenses. Some basic guidelines for materials selection are listed below. But don’t worry, our optician will help you select the best material for your prescription. Remember, THIN IS IN!
Scratch Resistant Plastic
A basic plastic lens is best for mild prescriptions of less than +/- 3.00.
Polycarbonate is 30% thinner than plastic, it is light and ten times more shatter resistant than plastic. Polycarbonate is safer than plastic because of its shatter resistance. Polycarbonate is best for prescriptions between +/- 3.00 and +/- 5.50. For prescriptions above +/- 5.50, the optical characteristics of polycarbonate begins to decline.
Hi-Index is the thinnest possible material for patients who require a strong prescription. Hi-Index is a dense material that bends light more efficiently than plastic or polycarbonate. This means that a thin hi-Index lens can have the same prescriptions as a thick plastic or polycarbonate lens. The optical quality of hi-index is superior to polycarbonate. Patients concerned about getting “coke bottle glasses” should consider hi-index lenses because they can be made incredibly thin!
Do you have trouble with night-time driving? The new halogen headlights on cars are so bright that they often dazzle your vision. If you experience glare on your glasses, then you need anti-reflective coating on your spectacle lenses. Do you experience headaches or eyestrain when using a computer? A-R coating reduces reflections and eyestrain associated with computer use. Anti-reflective coating improves visibility by eliminating bright reflections on your lenses.
Crizal anti-reflective coating is the only A-R coating that our doctors recommend because it is guaranteed not to scratch for two years. Some inferior A/R coatings scratch and peel after only a few months. Not Crizal! If your new Crizal lenses scratch during the first two years we will remake them one time free of charge! Ask for Crizal anti-reflective coating on your new spectacle lenses.
Have you heard about the recent advances in photochromic lens technology? The newest Transitions lenses darken outdoors, but remain perfectly clear inside. That’s because Transitions lenses only darken in response to the ultraviolet rays from the sun. Transitions lenses will not darken indoors under artificial lighting. Still not convinced? Stop by our office and ask to see a sample of Transitions lenses
