Aspheric lenses can be made for single vision, bifocal and progressive eyeglasses for the correction of nearsightedness, farsightedness, astigmatism and presbyopia. Although most aspheric lenses are made from high-index materials, they can also be made out of a variety of other types of materials, including plastic. Here are some key points on how to buy eyeglasses with aspheric lenses.
The type of frame selected to use with aspheric lenses is important for a number of reasons. Although aspheric lenses give people with a strong prescription more options when choosing eyeglass frames, the best looking eyewear generally results when a frame is not overly large and the eyes are centered in the middle of the frame opening.
On the other hand, the benefits of an aspheric lens can be cut off if the frames are too small.
A qualified optician will help you to choose the best type of frame for your new aspheric lenses. Taking measurements for these lenses involves greater care and skill on the part of the optician but will take only an extra minute or two of your time.
Making the intricate curves used in aspheric lenses makes them a bit more expensive than traditional lenses. However, the extra investment in thinner, lighter lenses pays high dividends in exceptional visual and cosmetic benefits. Aspheric lenses can be compared to wearing the right frames. They help to flatter your appearance.
An anti-reflective coating is highly recommended for aspheric lenses as they tend to be more reflective on both the front and back surfaces. This is due to the fact that the lenses are flatter and positioned slightly closer to the face than traditional lenses.
See the World Differently
You may notice that things look different through your new aspheric lenses because these lenses can reduce the magnifying or miniaturization of objects by up to 20 percent. Objects will look different in size than what you’ve been used to experiencing.
However, in just a few days your eyes will adjust to these changes and you will begin to enjoy seeing your world in a more natural way.
