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 far distance, mid distance or reading. Far distance- If you wear glasses all day, but don't have bi/varifocals or mostly need these glasses to see things in the distance.E.g. For driving. Mid distance- If you mostly need these glasses for working on the computer or something else at arms length or you are a musician and need these glasses for reading music. Reading- If you need to read things close to you.Papers, document, etc
Bifocal Lenses with a Line
A bifocal lens means a lens with two points of focus. A small portion of the eyeglass lens is reserved for the near-vision correction. The rest of the lens is usually a distance correction. Generally, you look up and through the distance portion of the lens when focusing on points farther away, and you look down and through the bifocal segment of the lens when focusing on reading material or detail work up to about 18 inches away.
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.
WHAT'S LENS INDEX?
Lens index is a number that describes how thick or thin your lenses are. The higher a lens' index is, the thinner it becomes. Higher prescriptions require higher index lenses, while lower prescriptions require lower index lenses.
WHAT ARE HIGH INDEX LENSES AND WHAT'S THE DIFFERENCE?
High index lenses are thinner, more powerful lenses. They're lightweight and stylish, but are mostly reserved for those with higher vision correction needs. While most prescriptions are compatible with more than one specific index, it's up to you to decide which one fits your personal needs!
The difference between your glasses' lens index can make a huge impact. Deciding which you should get depends on your prescription and your lifestyle. Thicker lenses are more affordable, but can only accommodate lower vision correction needs. Thinner lenses are lightweight (and more stylish!) and can accommodate MANY kinds of vision needs, including higher prescriptions.

If our selection of sunglasses isn't enough for you, our color-tint coatings let you create your own. We offer 6 colors for you to choose from.
Gradient-tint lens coatings start as dark tint at the top of a lens and then progressively lighten toward its bottom. The result is a pair of shades that offer you sun protection and privacy, but offer you varying degrees of light.
Mirrored sunglasses are sunglasses with a reflective optical coating on the outside of the lenses to make them appear like small mirrors. They are gaining popularity in high fashion as well as sport performance spheres.
Polarized lenses are used in sunglasses to reduce glare from reflective surfaces such as the surface of a lake or the hood of a car. They accomplish this feat through a process called polarization, much like a venetian blind controls sunlight through a window.
Anti-Scratch coating for eyeglasses is a coating that is applied to lens surfaces. It helps to prevent minor scratches that can easily happen to a regular lens. These minor scratches can damage the surface of the lens and impair vision. An anti-scratch coating acts as a protective layer thus making the lenses more durable.
As light encounters a lens three things happen. 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.
