Lens Usage
Single-Vision Lenses
Single Vision lenses are the standard eyeglass prescription. These glasses have only one viewing area throughout the entire lens and the correctional area can be for distance, reading or intermediate.
Distance - If you wear glasses all day, but don't have bi/varifocals or mostly need these glasses to see things in the distance.
Reading - If you need to read things close to you.
Intermediate - If you mostly need these glasses for working on the computer or something else at arms length.
Bifocal Lenses With A Line
A bifocal lens means a lens with two points of focus. A small portion of the eyeglasses lens is reserved for the near-vision correction. The rest of the lens is usually a distance correction.
Progressive Lenses - No Line
Progressive lenses are the closest to how natural vision is that you can get in a pair of prescription eyeglasses.
They are more than just a defined near and distance correction in one lens. Rather, progressives provide a smooth transition from distance through intermediate to near, with all the in-between corrections included as well.
This constant graduation of the prescription means that you can look up to see in the distance, look ahead to view your computer in the intermediate zone, and drop your gaze downward to read and do fine work comfortably close up.
Prism Lens
Prism glasses feature lenses designed to correct double vision caused by underlying medical issues. If you need them, your prescription will feature numbers telling us how to shape your lenses to correct your vision.

Shield your eyes with
Blue Light lenses
Blue light, like other colors of visible light, is all around you. The sun emits blue light. So do fluorescent and incandescent light bulbs. Human beings are exposed to more blue light than ever because of the widespread use of devices that rely on light-emitting diode (LED) technology.
Computer and laptop screens, flat-screen televisions, cell phones, and tablets all use LED technologies with high amounts of blue light.

Mirrored lenses
From the outside mirror lenses look opaque, however, the wearer of the glasses is able to see perfectly fine. Mirrored sunglasses come in several different styles and designs, and are often a good choice for those who like to make a statement.

Polarized Lenses
When a lens is polarized, it has a built-in filter that blocks bright, reflected light. This intense light is known as glare. And polarized sunglasses get their best feature: the reduction or elimination of glare. When glare is reduced, your eyes feel more comfortable and you can see your surroundings more clearly.

Lens Coatings
Anti-Scratch Coating
It helps to prevent minor scratches that can easily happen to a regular lens. An anti-scratch coating acts as a protective layer thus making the lenses more durable.
Anti-Reflective Coating
Some of the light passes through the lens, this is called refraction, some is absorbed and converted into heat energy (very small amounts) and the rest bounces off. When light bounces off the lens this creates glare. Glare or reflections can be annoying and in some severe cases can decrease visual acuity. To improve both the vision through the lenses and the appearance of the glasses, an anti-reflective coating (also called AR coating) is applied.
UV Protective Coating
UV Coating is a beneficial lens treatment. It is an invisible dye that blocks ultraviolet (UV) light. Just as sunscreen keeps the sun's UV rays from harming your skin, UV-protective treatments for eyeglasses lenses block those same rays from damaging your eyes.
Super Hydrophobic Coating
Super Hydrophobic (water resistant) coating keeps water drop, dirt, and smudges off your lenses while making them easier to clean. Lenses with this premium coating stay sparkling twice as long.
