Presbyopia
Presbyopia is an eye condition in which light rays from a near object from come to a focus behind the retina.
This is very close to hyperopia, but the difference is that this condition results from a decreased ability for the lens to focus, which is called commonly called accommodation, and happens as we get older.
Very often presbyopia can become symptomatic at around 40 years old of age.
Presbyopia may be treated with eyeglasses, either bifocals or, more commonly, dedicated reading glasses.
Age-Related Macular Degeneration Disease
Age-related macular degeneration or AMD is a disease that affects your central vision.
AMD is a common cause of vision loss for persons of 60 years old of age.
The center of your vision is usually only affected for AMD.
Most people will not go blind from age-related macular degeneration disease.
It can sometimes make it difficult to read, drive, or to do other daily functions that need fine central vision.
The macula is in the center of the of the eyes retina.
The macula is the light sensitive tissue layer in the back of the eye.
When you read the light is focused at your macula.
Millions of cells change this light into the nerve signals that then communicate to the brain what you are now seeing.
This is what is commonly called your central vision.
Measuring Pupillary Distance or PD
Pupillary Distance measurement is used correctly position the lenses within the eyeglass frame have selected. Have someone measure the distance from the center of the pupil in one eye to the center of the pupil in your other eye.
To measure your pupillary distance:
Place the millimeter ruler on the bridge of your nose, and have your friend measure the distance between the center of your pupils, or try to do it yourself by looking in the mirror.
As a general estimate many adults have a pupillary distance between 54 and 66, and many kids can be between 41 and 55.
Other Types of Lenses
We offer several other types of lense styles a small price increase instead of charging the full list price. Here are some of the different lense styles and options available.
Seiko® 1.67 Super-High Index Lenses
Seiko® 1.67 lenses are our lens of choice for those with very high prescriptions. They are thinner than any other 1.60/1.66 "high-index" or "thinnest" lenses others may sell. If you've never had 1.67-index lenses before, you'll be surprised how thin your eyeglass lenses can be! They also come with both 100% UV and tough scratch-resistant coatings applied to both sides of the lenses, as well as polished lens edges, at no extra charge. Though they are generally recommended for prescriptions above +4.00/-6.00, they can make any prescription over +/-3.00 (especially in larger frames) look great!
Sun Lenses
Tinted CR39 Sun Lenses
Sometimes referred to as hard-resin, our standard sun lenses are made using the highest optical-grade CR39 lenses. In addition to its fantastic optical clarity, CR39 can be tinted much darker than polycarbonate (which is why we use it). In addition to the tinting, we apply 100% UV-protective and tough scratch-resistant coatings to both sides of the lenses. CR39 is recommended for low-to-moderate prescriptions, between +3.00 and -4.00.

CR39 Polarized Lenses Package
Polarized lenses have filters that block out reflected light. They virtually eliminate the glare caused by reflections from horizontal surfaces, making them ideal for driving or water-activities. This filtering of incoming light (rather than darkening it) leads to sharper vision and better color vision. Polarized lenses are naturally UV-protective and we apply our tough scratch-resistant coating to both lens surfaces. The CR39 material is recommended for low-to-moderate prescriptions, between +3.00 and -4.00. If your prescription is outside this range, check out our polarized polycarbonate lenses.
Polarized Polycarbonate Lenses Package
Polarized lenses have filters that block out reflected light. They virtually eliminate the glare caused by reflections from horizontal surfaces, making them ideal for driving or water-activities. This filtering of incoming light (rather than darkening it) leads to sharper vision and better color vision. Polarized lenses are naturally UV-protective and we apply our tough scratch-resistant coating to both lens surfaces. Polycarbonate is the lightest, most impact-resistant material made. With an index of refraction of 1.59, polycarbonate is thinner than standard (CR39) optical lenses. They are ideal for children or people with an active lifestyle. They are recommended for prescription ranges between +/-4.00 (and/or cylinder ranges between +/-2.50). It can still be used for higher prescriptions up to +4.00/-8.00, by custom "surfacing" the lenses.
Clear-Indoor/Dark-Outdoor Lenses
We are proud to carry the latest Next Generation™ Transitions® Lenses, which go from clear indoors to as dark as sunglasses outdoors. Their advanced technology adjusts to changing light, so you see clearly and more comfortably in virtually any light condition. They have a refractive index of 1.50.
Indoors, Transitions Lenses® are as clear as your regular eyeglasses. Outdoors, they quickly darken into sunglasses. They work so well, in a recent clinical study, four out of five eyeglass wearers preferred Transitions to their regular lenses. And Transitions provide 100% UV protection. The CR39 material is recommended for low-to-moderate prescriptions, between +3.00 and -4.00. If your prescription is outside this range, check out our Polycarbonate Transitions® Lenses.
Polycarbonate Quantum® Transitions® Lenses
Transitions® Lenses go from clear indoors to as dark as sunglasses outdoors. Their advanced technology adjusts to changing light, so you see clearly and more comfortably in virtually any light condition. The Quantum® technology allows the vision through high-index lenses to remain clear through all lens-darkness levels.

Bifocal & Progressive No Line Bifocal Lenses
Clear Polycarbonate Flat-Top 28 Bifocal Lenses, Flat-top 28 refers to regular bifocal lenses where the distance and reading portions are separated with a 28 mm line rather than one going from edge-to-edge.
Polycarbonate is the lightest, most impact-resistant material made. With an index of refraction of 1.59, polycarbonate is thinner than standard (CR39) optical lenses. As the safest material available, polycarbonate is ideal for bifocal wearers with an active lifestyle or for those who have one eye that is much better than the other (amblyopia), so your good eye is always protected. They are recommended for prescription ranges between +/-4.00 (and/or cylinder ranges between +/-2.50).

Anti-Reflective Coating
Our premium anti-reflective coating is ideal for computer use and night driving. They work by increasing the light transmission through the lenses, providing you with the clearest, sharpest vision at all times. Any great-looking pair of glasses will look even better: people will see your eyes through the lenses, not the light reflection! For this reason, we automatically include anti-reflective coatings with any of our rimless eyeglass packages. (Note: applying anti-reflective coatings to sunglasses, bifocals/progressives, Transitions® Lenses, or prescriptions above -6.00 may cause a 24-48 hour delay in delivery.)
