Lens Thickness Material

CR-39 is the most common form of plastic and most widely used material in prescription eyeglasses. CR-39 is a lighter option than glass and has the added benefit of not breaking as easily as a glass lens.

Polycarbonate lenses are the safest option of lens materials available. Polycarbonate, a form of plastic, is far superior to any other plastic in its durability and resistance to shattering. On average Polycarbonate is 30% thinner and lighter than CR-39. This extremely strong material is used to make bullet proof windows because of its impact resistance and shatter-proof characteristics.

On average 1.67 high-index plastic lenses are 50% thinner and lighter when compared to CR-39 plastic lenses.

Glass is the oldest existing form of lenses in the eyewear industry. It's main benefit over other materials is it's resistance against scratching, however, glass lenses are more prone to shattering and are extremely heavy compared to newer aged materials.

On average, 1.56 mid-index plastic lenses are 30% thinner and lighter when compared to CR-39 plastic lenses.

Will These Glasses Be Used as Safety Glasses, or by a Child Under the Age of 18?

Eyeglasses used as safety glasses must be made with Polycarbonate lenses. Polycarbonate lenses are impact resistant providing the best available protection against injury to the eyes from flying debris such as wood, metal, and plastic etc.

By law all eyeglasses made for children under the age of 18 are required to be made using Polycarbonate lenses. Polycarbonate lenses are shatter proof and are used to protect the eyes against injury in the event of accident (sports related, slip and fall, air bag in auto collision etc.)

For your convenience if "yes" is selected only Polycarbonate lens choices will be made available in the lens material selection portion of the ordering process.

Transition Lenses

Transition lenses are lenses with the added benefit of auto adapting tint. The degree of tint reacts based on the amount of exposure to sunlight and UV rays. Transition lenses are 100% clear while indoors and also during night time conditions. Transition lenses quickly turn into sunglasses when exposed to sunlight and block 100% of UVA and UVB rays. Indoors these lenses are perfectly clear and they will darken up to an 85% tint in direct sunlight. Available in Gray or Brown.

Polarized

This option is the ultimate form of protection and comfort when lenses will be used as sunglass lenses only. Polarized lenses never fade and block horizontal light, resulting in the reduction of glare. Polarized lenses block 100% of the sun's harmful UVA and UVB rays. The clarity, comfort, and protection that Polarized lenses provide is far better than any other option available for sunglass lenses. This option is highly recommended to anyone with sensitivity to sunlight and/or glare. Polarized lenses are available in Gray, Green, or Brown.

Solid Tint / Gradient Tint

A light tint could be used indoors and/or outdoors and will appear as a hint of color. Can be applied as solid (the whole lens is the same darkness) or gradient (the lens is darkest on top and gradually lightens towards the bottom). On a scale of 1-100, a light tint would be classified as 10-30%. A medium tint could be used indoors and/or outdoors and will appear an obvious color. Some people would consider a medium tint too dark for indoors, but may also attribute the color to reducing glare from bright office lighting. Can be applied as solid (the whole lens is the same darkness) or gradient (the lens is darkest on top and gradually lightens towards the bottom). On a scale of 1-100, a medium tint would be classified as 40-60%. A dark tint is used outdoors only for sunglasses, as they would be too dark to be used indoors. The best colors to choose for sunglasses are typically gray or brown. Can be applied as solid (the whole lens is the same darkness) or gradient (the lens is darkest on top and gradually lightens towards the bottom). On a scale of 1-100, a dark tint would be classified as 65-90%. We do not recommend tinting lenses darker than 85% because it could lead to impaired vision.

Anti-Reflective Coating

Anti-Reflective (AR) Coating or Anti-Glare coating is a coating that reduces glare, while at the same time produces a pleasant cosmetic appearance by making your eyes more visible to others; ideal for computer use and night time driving. With an anti-reflective coating, reflections are eliminated and eyeglass lenses look thinner or non-existent, eliminating the otherwise "white light" that you normally see on lenses without this coating.

This coating includes a UV filter for added protection and is available in both generic and name-brand forms as well. One and two year warranty coatings are available to choose from.
