Lens Choice Information
Maple Leaf Optical offers single vision, flattop bifocals, and trifocal lenses. In addition, below are some of the most popular lenses available. Why choose one over the other? Allow one of our eye care professionals to help you understand these lens choices:
Computer glasses differ from regular eyeglasses or reading glasses in a number of ways to optimize your eyesight when viewing your computer screen. Computer screens usually are positioned 20 to 26 inches from the user’s eyes. This is considered the intermediate zone of vision – closer than driving (distance) vision, but farther away than reading (near) vision. These glasses put the optimum lens power for viewing your computer screen right where it is needed for a clear, wide field of view without the need for excessive focusing or unhealthy posture.
By using new manufacturing techniques and more powerful computers, lens manufacturers are able to make truly custom lenses. Digitally surfaced lenses use new technology to optimize the prescription throughout the entire lens.
Photochromic lenses, such as those made by Transitions Optical, are clear (or nearly clear) during indoor use and darken automatically in response to sunlight outdoors. They also protect your eyes from 100 percent of the sun’s harmful ultraviolet radiation.
Polarized sunglasses improve vision and cut glare and haze for more comfort. For years polarized sunglasses have been popular with boaters and fishermen who need to reduce reflected glare from surrounding water.
Progressive lenses, sometimes called “no line or invisible line” lenses, provide a more youthful appearance by eliminating the visible lines found in bifocal and trifocal lenses. Progressive lenses offer other advantages such as allowing you to see at any distance, including arm’s length for computer use and up close for reading. Today’s new and improved digitally surfaced lenses offer a wider intermediate zone and smoother transitions between zones. They’re comfortable from the moment you put them on. Don’t be fooled! All progressive lenses are not created equal. Wearing the correct progressive lens makes all the difference.
When you reach the point of not being able to read up close without stretching your arms to the limit, you may need to consider single vision reading glasses. Reading glasses come in two main styles: full frames, in which the entire lens is made in the reading prescription, and half-eyes, the smaller “Ben Franklin” style that sits lower down on the nose. Full reading glasses are suitable for people who spend a great deal of time concentrating on material close up.
