Glasses And Frames
Following your eye examination, if the doctor determines that you need corrective lenses, you will be given a copy of your eyeglass prescription. This prescription can be used at the optical of your choice for ordering new eyeglasses. Our opticians are trained to assist you in selecting the frame and les options which will maximize your visual efficiency, while fulfilling your needs for comfort and style.
There are a variety of materials which are now used to produce eyeglass frames. In general, you can categorize these into two primary classes, plastics and metals. In consultation with an optician, you will decide which frame material and style best suits your individual needs and lifestyle. In making your selection, you may wish to consider some of the following:
Primary Use: full-time daily, reading only, driving only, sports/safety purposes
Frame Style: which shape, color and size is most appropriate for my face?
Durability: work environment, lifestyle, hobbies, hypoallergenic needs
Single vision lenses will correct for myopia (nearsighted), hyperopia (farsighted), and astigmatism.
Multifocal lenses will correct for both distances and reading vision. Most people will need this type of lens by the time they are reaching age 40. A multifocal lens has a magnifying section built into the prescription to allow for clear vision when reading.
Bifocals have a line separating the upper distance prescription from the lower reading prescription.
Trifocals have two lines which separate the distance, intermediate, and reading segments of the prescription.
Progressive addition lenses have no lines to get int the way, and provide clear uninterrupted vision at all distances.
Glass lenses, while once the standard, now account for no more than 5 to 10% of new prescriptions. Glass lenses are heavier than other types, and may also shatter upon impact.
Plastic lenses are approximately half the weight of the glass and provide more impact resistance. Plastic is the most commonly used lens material today.
Polycarbonate lenses continue to grow in popularity for their characteristic strength, thinness, and light weight. They are more impact resistant than glass or plastic, making them ideal for safety glasses, sports activities, and children’s glasses. People with strong prescriptions often prefer the thinner, lighter lenses available in polycarbonate material.
Scratch resistant coatings may be applied to the surface of a lens to protect it from scratches which may interfere with your vision and scatter light. Scratch resistant coatings may extend the life of your lenses.
Ultraviolet coatings are recommended to block the UV light from the sun which may contribute to cataract formation. This is applied to the lens as clear coating.
Anti-reflective coatings are used to eliminate the reflections of light which commonly occur on the surfaces of a lens. Anti-reflective coatings may reduce eye fatigue caused by light reflection and computer use, and may improve vision when driving in low light conditions by eliminating glare. This coating will also provide a more natural looking appearance while wearing your glasses
Aspheric lenses are designed to minimize the curved surface of the lens, making it flatter and lighter, and reducing distorted appearances. Aspheric designs are most helpful when ordering strong prescriptions.
Photochromic lenses are designed to darken in sunlight, and lighten when indoors. If you enjoy outdoor activities, or work outside, a photochromic lens may be an ideal choice.
Polarized lenses can be incorporated with a sunglass tint to enhance visual contrast when driving or outdoors. Polarized lenses are able to filter out the glare produced when light reflects off surfaces such as water and snow.
