Lens Design is the physical layout of the lens. Here form truly follows function. This is quit evident with the addition of "Computer Glasses", as more of our time is spent in front of a computer monitor. And with other new advances like Progressives, rest assured lens design will always keep pace with our visual needs.

Single Vision:
Single vision lenses function as all purpose glasses for persons who have normal accommodation. Persons who normally wear bifocals or trifocals can use single vision for distance or near lenses. Single vision lenses can also function as occupational glasses for certain types of work. Single vision lenses are available in all lens materials.

Aspheric Lenses:
These lenses provide special visual and cosmetic benefits for stronger corrections and increase edge to edge clarity. Flatter than conventional lenses, aspheric eliminate the "bulgy" appearance of strong plus lenses and greatly enhance the appearance of finished eyewear.
Aspheric Plus
Persons with strong nearsighted corrections also benefit from thinner, lighter weight glasses when their lenses are aspheric. Because aspheric lenses are positioned closer to the face, there is less eye magnification with farsighted corrections and less of the "small eyes" look with nearsighted corrections. Aspheric lenses are often made of high index materials for the ultimate in thin lenses.
Aspheric Minus

Progressive (No-line Bifocal):
These lenses provide all the benefits of bifocals but add the feature of continuous clear vision at all distances, including mid-range distance (arm's length). Progressives have the cosmetic advantage of appearing to be single vision lenses so they never reveal that the wearer is using bifocals. Progressives are available in all lens materials and also made in aspheric form. Because of their many benefits, they are becoming the lens of choice for bifocal and trifocal wearers.
Progressive Design
Flat-Top Bifocal:
This is the most popular bifocal format and is available with the bifocal portion made in a variety of widths to help with various close-up occupations. Flat-top bifocals are made in every type of lens material.
Executive Bifocal:
Sometimes used for those who need a wide field of vision for near work (accountants, for example), Franklin style bifocals have a distinctive appearance and are thicker because of their design. They are generally only available in glass, hard resin and photochromic glass. They are being replaced by wide flat-top bifocals.
Trifocals:
Trifocals come in a variety of designs. Flat-top trifocals are the most widely used form. The added segment provides clear vision at arm's length distance, the area that is usually blurred for bifocal wearers. Trifocals are available in all lens materials.

Safety Glasses:
Each year roughly 2.4 million Americans experience some type of eye injury.[1] And this figure only represents those injuries seen by hospital emergency rooms. Your initial thought might be to blame industry for these injuries, however workplace eye injuries have decreased from over 3,000 per day to roughly 1,000 per day. Regulatory agencies have done a great job at identifying the need for safety eyewear and employers have made safety eyewear available to all workers who come in contact with potentially hazardous equipment. Safety frame manufacturers have created frame styles that are fashioned after many of the popular “dress” eyewear styles to increase compliance. So where are the rest of these injuries occurring? Forty-five percent, or just over 1 million injuries, occur in or around the place we feel most safe, our homes. And an additional 840,000 injuries affect children under the age of 17.
The statistics are alarming, but the most disturbing fact about eye injuries is that 90% of reported eye injuries could have been prevented through the use of protective eyewear according to Prevent Blindness America. How often do you cut your grass in your best dress shoes? Probably never, but I would bet that you wear your dress eyewear when cutting the grass. Are your feet, or even worse your shoes, more important to protect than your eyesight? View safety eyewear for home and kids eye protection just like you would seatbelts for driving and helmets for riding a bicycle. Our society is gradually becoming more safety conscious and usage of these types of safety devices is more commonly accepted.

Computer Glasses:
You're not alone! Over 60 million Americans who routinely use computers suffer from Computer Vision Syndrome (CVS). Symptoms include eyestrain, headaches, blurred vision, and a dry, burning sensation.
The glass of your computer monitor is like a giant reflecting dish. While you use your computer, many of the light rays around you bounce off your monitor and blast directly into your eyes. That's why many computer and monitor manufacturers recommend you use computer glasses to protect your eyes.
Computer Glasses provide patented, clinically-proven vision relief, to help protect you from developing the symptoms of CVS. |
