High Index Lenses Blue Light

Trivex is really a relatively new plastic lens material that is being used as a substitute for polycarbonate lenses. Trivex is optically more advanced than polycarbonate in fact it is lighter. Like polycarbonate it offers 100% UV protection in fact it is extremely durable. Most importantly, Trivex is a good replacement for polycarbonate lenses that need to be tinted, because Trivex could be easily tinted but polycarbonate cannot. Trivex is much better suited for tinting and is an excellent choice for rimless drill mounted frames.

The difference high-index lenses make in turning thick glasses to thin glasses could be very dramatic assuming you have a strong prescription. If some refractive errors tend to be more severe, individuals will need to use higher prescriptions. These stronger prescriptions may contain thick and heavy plastic lenses.
Your smartphone and screen exposes your eyes to harmful blue light rays that hurt your vision. Protect your eyes and add our blue light protection, computer lenses in your frames starting at $97. Between computers, tablets, and smartphones, we need help from our glasses more than ever before. All that screen time could be hard on your own eyes and may cause digital eye strain. High-index lenses bend light more efficiently when compared to a standard lens, which means thinner, lighter lenses can be used to correct nearsightedness, farsightedness, and astigmatism.
Trivex may be slightly thicker than polycarbonate lenses, but because of its specific gravity the weight will be similar. Anti-reflective coating (also called “anti-glare coating” or AR coating) helps improve vision and reduce eye strain through the elimination of reflections from both sides of the lenses. AR coating is particularly recommended for high-index lenses because high-index lenses reflect more light than standard plastic lenses. The advantage of AR coating is also obvious at night when it creates your lenses almost invisible, to help you have better eye connection with people and may see more clearly. Our progressive lenses are also scratch-resistant, and show anti-reflective, anti-static, and UV protective coatings. It provides a more natural correction of presbyopia than bifocal or trifocal prescription eyeglasses.

Eyeglass Lens Basics

1.74 High-Index lenses are the thinnest and lightest lenses you can buy from Payne Glasses. They are recommended for folks with a solid eyeglass prescription, typically for powers above +3.00 because they are aspheric in design. The 1.74 is made thinner and flatter than standard spherical lenses, which helps reduce the magnification of the eyes. 1.59 Polycarbonate lenses are made of material perfect for active use, including glasses for kids, sports goggles, and safety glasses. The 1.59 Polycarbonate is beneficial in rimless glasses, which while stylish, lack the protection of a rim on all sides and then the lens has to be made stronger.

• A high-index lens can be thinner while still effectively bending the light to improve your vision.
• being reflected off the water.
• When added to your lenses, anti-reflective coating provides sharper, crisper vision by blocking glare from screens and other light sources both during the day and at night.
• So, if you need the thin, attractive eyeglasses, choose lenses made of a material which has a high index of refraction .

Ask your optician or optometrist about these options and try a sample, as it might not get dark enough for you. Vertically polarized lenses decrease bright glare and reflections by blocking horizontal polarized reflected light. Scratch-resistant coatings are put on leading and back of lenses in the manufacturing process. Aspheric lenses are also much much lighter than standard spherical lenses. Trivex is much lighter than standard plastic but not quite as thin as polycarbonate.

MR-8™ (US MR-95™) is suited to any strength ophthalmic lens and is a new standard in ophthalmic lens material.

High-index lenses are constructed with a special plastic material that allows your eyeglasses to be thinner and lighter because they bend light better. Many people appreciate using high-index lenses because they look better cosmetically and feel convenient. An anti-reflective coating is applied to eyeglass lenses to lessen the quantity of internal and external reflections on a lens. This coating increases the level of light transmitted through the lens, which improves the caliber of vision. As the prescription strength increases, lenses get thicker and heavier. Higher-index material provides thinner and lighter lenses, which makes them a good option for those who have a strong prescription.

A person might need similar corrections in both eyes or different corrections in each eye. Displayed after each of the letters will be a numerical value with the plus (+) or minus (-) sign. The higher the quantity, the more correction a person’s eye needs. The plus sign indicates a person has farsightedness, and the minus sign indicates a person has nearsightedness. Keep in mind, you need to speak with an optician before making a decision on the lens material.

Eyeglass Frames

Professional sunglasses are recommended to utilize since childhood. Despite having our anti-scratch coating, it doesn’t imply that your lenses will not scratch at all. Please understand that even the very best anti-scratch coating can’t 100% protect your lenses from wear and tear.
