In air, this type of coating theoretically gives zero reflectance for light with wavelength equal to four times the coating’s thickness. Reflectance is also decreased for wavelengths in an easy band around the center. A recent report by The Vision Council found that over 65% of modern professionals experience Digital Eye Strain frequently. The planet…
The Abbe is the measure of how well an optical material transmits light at different wavelengths and grades color accuracy. A high Abbe value means that colors will be sharper and clearer as the lightweight material is impact resistant for sports safety glasses or prescription eyeglasses. For children’s eyewear, select a sturdy frame and lightweight…
In 1971, the Food and Drug Administration published a new policy that stated that prescription lenses should be impact-resistant by February of 1972. Manufacturers starting switching to polycarbonate, or plastic, lenses, that have been more durable, less expensive and lightweight, but also easily found scratches. Scratch-resistant materials are present in anti-Starch coating either as binders,…
The crisper vision and improved eye safety from Trivex make them ideal for both children and adults. Other types of plastic or polycarbonate lenses require specific filters for UV protection, which can add to the cost. No eyeglass lenses — not glass lenses — are 100% scratch-proof. In terms of eye safety, polycarbonate and Trivex…
reasons. Semi-rimless frames may also be an ideal choice for those who benefit from the extra comfort and minimalist feel. Although Trivex appears like the perfect material for glasses, here are a few downsides. First, Trivex is a new material, so it can be hard to find among glasses retailers. This implies you won’t get…
please e mail us now. Our expert team have vast years of working experience in the optical industry and can help guide you through your choice making process. Polycarbonate lenses have become resistant to tint as opposed to plastic lenses which accepts tints. You don’t necessarily need to purchase your eyeglasses from the eye doctor…
However, you will notice a difference with anti-reflective coating on any lenses. Anti-reflective coating provides a smoother surface which can be cleaned easily. This is also a useful feature if you work outside because the lenses will be clearer, even in poor weather. This is to ensure that the lenses have a clean foundation for…
Their exceptionally smooth yet hard surface also repels dirt and makes them much easier to clean. This guarantees lasting visual comfort, outstanding visibility and makes your glasses last a long time. Together, we’ll choose the best solution for you based on your needs – for example, a coating with a blue light filter or one…
Trivex is also very resistant to material deflection due to the higher temperatures encountered during hard coat curing processes. These can reach over 266 degrees and may result in optical distortions of the finished lens. Trivex is 90 percent more resistant to this sort of induced distortion than polycarbonate. Those who desire to avoid scratches…
eye gear and sports goggles are made of polycarbonate lenses, even when no vision prescription is needed. Furthermore, polycarbonate boasts built-in protection from the sun’s Ultra violet rays, making this an ideal lens material for time spent outdoors. Since that time, polycarbonate lenses have become the typical for safety glasses, sports goggles and children’s eyewear….
