Lens Index & Coatings

Lens Index Introduction

Our lenses are all made with advanced plastics and are available in seven indexes, which determine how thick or thin your glasses lenses are. Those with a stronger prescription often prefer high-index for thinner lenses, while those who are active may need impact-resistant options. It is important to choose suitable lens index according to your prescription, as this will not only impact aesthetics/thickness of lens, but also the comfort of the glasses and lens. When you fill in your prescription, our website will recommend the suitable lens index for you automatically. Applying higher index lenses (1.60 index and above) can solve the problem of having a thick edge on a negative lens, or a thick center on a positive lens. Combining a higher index lens with an aspheric shape results in a lens which is noticeably thinner and lighter, bringing better vision, and a more comfortable wearing experience. However, the ultimate thickness of the lenses is determined by the frame size (including lens height, lens width), frame material and your PD. If you choose a big frame the lens edge will undoubtedly be thick. Frames with thin metal rim will also make the lens look thicker. If the frame is not the best for your PD, the lens may not be beautiful and thin as you expect.

What lens thickness should I get?

The lens thickness 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 ALL kinds of vision needs, including higher prescriptions!

Selectable Coatings

Anti-fog Coating helps prevent your lenses from fogging up. The anti-fog coating is on both sides of the lenses.

Anti-glare Coating reduces glare, reflections, and halos, and filter various strong lights.

Mirror Coating is a colored reflective optical coating on the outside of the lenses to make them appear like small mirrors. You can choose different tints of the mirror coating. It decreases the amount of light passing through the tinted lens by a further 10-60%, especially useful for occasions of sand, water, snow, and higher altitudes.

Photochromic Coating makes lenses dark when exposed to the sunlight and change to clear when the wearer is indoors.

Tint is a permanent color added to your lenses, making your glasses become a pair of prescription sunglasses.
