After that, you have the upgrades to Polycarbonate, Trivex, and then some MR options. The 1.57 mid-index progressive polymer lens covers SPHs of -4.00/+2.00 or lower, CYLs of +/- 6.00 or lower, and an ADD power of +3.50 or lower. The 1.53 mid-index Trivex progressive lens has, like the single-vision Trivex lens, the highest impact resistance of all the lenses we carry. 1.57 Mid-Index + Blue Blocker

1.57 Mid Index. - Up to 15% thinner than 1.50 lens. - Suitable for full-rim plastic/ acetate or full-rim metal frames. - BEST FOR RX RANGE +2.00/-3.75 OR BELOW.

Mid-Index Lenses. Next - Select Single Vision, No-Line Progressive, Lined Bifocals or Trifocals. Do you need Single Vision, Progressive no-line lenses, lined Bifocals or Trifocals? Below is a description of the different types of Mid-Index lenses available for your glasses. Your lenses at 1.57 must be polycarbonate, which is quite inferior, optically speaking, in powers over + / - 3.00 diopters. Don't be surprised if you see colored " fringes" around many objects in High index lenses come in a few different indexes. Which ones should I get? High Index Lenses: 1.67 Vs 1.74 High index lenses are thinner, lighter, and more appealing than standard lenses, but they come in several different indexes. If you’re shopping for high index lenses and aren’t sure whether to go for 1.67 or […] A client recently made me aware of a type of polymer being offered by one of the online guys called "Beyond UV". Its apparently a blue blocking 1.57, 1.61, and 1.67 index lens polymer that is supposedly "completely" clear (For some reason they recommend the 1.61 for the best optics, regardless of Rx, not sure why). I looked it up, and I honestly couldn't reconcile everything it says it could High-index plastic lenses are slim and sleek, providing an alternative option for strong prescriptions. High-index lenses are typically more expensive than standard plastic and mid-index varieties, but offer a wider choice of frames for people with stronger prescriptions, since the lenses are not bulky. High-index lenses reflect up to 50 percent more light than conventional glass or plastic lenses. For the best vision and appearance, it's a good idea to have an anti-reflective lens coating (AR coating) applied to high-index lenses. AR-coated high-index lenses transmit up to 99.5 percent of light to the eye for optimum vision.

The 1.57 mid-index progressive polymer lens covers SPHs of -4.00/+2.00 or lower, CYLs of +/- 6.00 or lower, and an ADD power of +3.50 or lower. The 1.53 mid-index Trivex progressive lens has, like the single-vision Trivex lens, the highest impact resistance of all the lenses we carry.

Mid-index lenses are slimmer and lighter than standard plastic types. A variety of protective treatments can also be applied, including photochromic and no-glare  and mid-index lenses fade out 20% faster* within the first 10 seconds. vGarde™ – The Everyday Lenses.

1.57 mid index single vision lenses means that the lens is thinner than standard plastic lenses. It is not the thinnest possible, nor is it impact resistant like Trivex 1.53 mid index lenses, or A mid index 1.57 is plenty in this -2.00 diopter scenario. Consider also that you will likely not wear those glasses for more than a few months, if you are working on vision improvement. Once you get close to -5.00 diopters, moving the index higher to a 1.61 is a good idea, if it fits your budget. 1.59 Index - Polycarbonate Lens Lenses in this index are made out of a special polycarbonate material. This means they include 100% UV protection. They're durable and impact-resistant, which also makes them perfect for everyone with most prescriptions. So I'm about to order from Zenni for the first time, and I'm having a little trouble making a decision. Should I get the 1.50 Standard index, 1.57 Mid-index, or polycarbonate choice (+$9) worth it, for 1.59? What's the difference between the lens indices? Is there any difference other than

21 Feb 2014 The 1.53 mid-index Trivex lens is a polymer lens that is the most impact-resistant lens available. It covers the same range as the 1.57 mid-index  1.57 Mid Index. - Up to 15% thinner than 1.50 lens. - Suitable for full-rim plastic/ acetate or full-rim metal frames. - BEST FOR RX RANGE +2.00/-3.75 OR BELOW. 1.57 Index - Thin and Light. For people with somewhat stronger prescriptions. These lenses are thinner and lighter, and handle SPH corrections between +/- 5.00  30 Aug 2013 A mid index 1.57 is plenty in this -2.00 diopter scenario. Consider also that you will likely not wear those glasses for more than a few months,  1.57 mid index lens is a base lens, great for full rim frames where the lens is supported on all sides, but is not recommended for semi rimless or rimless frames due  What does lens index mean? 1.50 Standard Index; 1.56 Mid-Index; 1.59 Polycarbonate; 1.61 High Index; 1.67 High Index
