Standard single-vision lenses These lenses have the same power all over. They are typically used for reading/driving/computer glasses or when a persons eyes need the same strength prescription to focus at both near and far distances.People under the age of 40-45 will usually just need single vision glasses.
Reading glasses After the age of approximately 45 years, people will often need visual aids for close-up tasks such as reading, or a different pair than what they use for far distance (TV/driving) if they already wear glasses.
Computer glasses After the age of 45, you might need different reading glasses for the computer than for other kind of reading. This is because the distance to the screen usually is longer than for reading a book, and normal reading glasses are too strong. Measuring the actual distance from the eyes to the screen is the best tool to decide the correct strength of the computer glasses, OR for other visual tasks (close or semi distant) different from normal reading distance.
Multi-focal/progressive glasses These are advanced glasses that have a zone in the lower part of the lens, so that the user can use them for all purposes, reading, driving or whatever needs he/she has for clear vision in an everyday situation. (For intense visual situations such as many hours work at a computer, an additional pair of reading/computer glasses might still be preferred).Multiple prescriptions built into one lens.
Coatings Anti-reflex coating to reduce the glare from uncoated lensesUltra High Quartz coating to make the lenses scratch resistantPolarized glasses to remove reflections from plane surfaces such as wet road, water or snowPhotochromic lenses that change color up to the level of sunglasses, according to light conditions. The lenses are clear like standard lenses before going out.
COLORED LENSES Polarized glasses to remove reflections from plane surfaces such as wet road, water or snowPhotochromic lenses that change color up to the level of sunglasses, according to light conditions. The lenses are clear like standard lenses before going out.Tinted glasses (like 15% color) for a functional and/or cosmetic softer effectSunglasses (like 85% color)Mirror glasses (silver, blue, red or green) that makes it impossible for others to see your eyes or where you see
Refractive index Index 1.5. This is the standard for our lenses.Index 1.6. This lens is harder and thinner than the standard lens. Required for superlight rimless glasses.Index 1.74. Light and ultrathin lens. Cosmetically appealing, especially with high power prescriptions.
