trivex vs high index reddit

For the best outcome, research all high-index options before deciding which one to use. The sales pitch of “shatterproof” is just that – a pitch. Be cause of its clarity, durability, ultra-lightweight properties, and resistance to chemicals, Trivex is used in production for helicopter and fighter jet canopies As a result of the success in military aircraft platforms, this high-quality material was brought to the eyewear industry in the early 2000s. Additionally, they are lighter than both of those lenses despite only having a marginally larger index than polycarbonate. The less expensive option he said I could also do would be zeiss trivex, which would cost $450 for the lens and he said doesn't necessarily need an antireflective coat. On the other hand, polycarbonate lenses have a higher index of refraction than Trivex lenses (1.58 vs. 1.53). Stable surface curvatures—Trivex has high resistance to circumferential deformation. Actually, I think trivex has better optics than high index. 1. In the past 20 years, in response to the demand for thinner, lighter eyeglasses, a number of lens manufacturers have introduced high-index plastic lenses. Trivex has a refractive index of 1.53. This video explains some of the differences between trivex and poly. In terms of thinness, this lens index is thinner than 1.50 lenses. This mid-index value enables lenses made from Trivex material to be thinner, lighter and more comfortable. It is thinner than trivex, and still has very good optics (better than 1.67). I don't think there is a wrong option, but if you have to have your lenses as thin as possible go with high index. It has better impact resistance and naturally blocks UV (granted, most good AR coatings block UV anyway). A high-index eyeglass lens allows people with a stronger prescription to wear a lens that is lightweight and thin. This ability further reduces weight and thickness. When aspheric curvatures are used on lenses, even more thickness and weight reduction can be achieved. Never had a complaint from a patient about weight, and I find that it usually cuts out to be about the same as 1.67 in terms of thickness. Refractive Index Trivex lens material has a 1.53 index of refraction. Archived. I could afford the more expensive ones but don't want to just waste money. Trivex is optically superior to polycarbonate and it is lighter. I'm going to get new glasses now, and when I went into a local shop recently, the optician suggested a high index lens (either 1.6 or 1.67) and said there was no reason to get Trivex, which cost 50% more. This ensures more comfortable glasses even if your farsightedness, nearsightedness, or astigmatism prescription is high. Press question mark to learn the rest of the keyboard shortcuts. If you don't mind it a little thick and … I'm getting my first set of progressive lenses, and the optician recommended zeiss premium progressive high index lenses (1.67 index) for the best optics. Are they really worth the extra expense? What is the advantage to a high index lens over Trivex, besides being thinner? However, if your prescription exceeds -/+6.00, you should consider a high index 1.67 lens or Varilux Physio Trivex lens in order to minimize lens weight and thickness. Unless you have a pretty thick frame and pretty small, Trivex wouldn’t be too good with a -5 rx. Here is a brief comparison of polycarbonate and Trivex lenses to help you decide which lenses might be best for you: Thickness. Press J to jump to the feed. I've had patients with scripts as high as -9 that liked Trivex because of the crispness it gives. Other high-index materials are classified by numbers. Hi-index lens material reduces lens thickness, making these lenses more comfortable and better looking by minimizing the size of visible lens edges for nearsighted wearers and reducing the magnified “bug eye” appearance associated with farsighted wearers. If you don't mind it a little thick and prefer function over fashion go with Trivex and save on money. 1. Both materials are excellent choices, with a plus for trivex eyeglass lens, especially the quality of vision and resistance, but also with a higher price. Compared to polycarbonate and other high index materials with a lower abbe value, Trivex’s higher abbe will create fewer chromatic aberrations. Trivex is an improvement over Polycarbonate. Thickness: Polycarbonate has a higher index of refraction than Trivex (1.58 vs. 1.53), so polycarbonate lenses are about 10 percent thinner than Trivex lenses, but as you see in the video, the difference may not even be noticeable. He said it would cost $550 just for the lens, which sounds expensive to me. Trivex vs Polycarb. High index materials tend to have lower Abbe numbers. Either has advantages and disadvantages. I don't necessarily need the thin lenses (the frames are relatively thick plastic ones). Actually, I think trivex has better optics than high index. Not sure whether to go with Trivex or Polycarb. However, the clarity in polycarbonate lenses is slightly less than Trivex and they tend to scratch more easily. Trivex is a relatively new plastic lens material that is being used as a substitute for polycarbonate lenses. It should be noted that I didn't tell the optician my RX since I didn't have it with me. I don't know much about Trivex - would that solve the distortion … The higher the number, the thinner and lighter the lens. Their strength and impact resistance makes them a great option for kids’, rimless frames, sports goggles and safety glasses, or anyone who is rough on their glasses. This lower specific gravity in mid range prescriptions, such as +/-3.00D to +/-6.00D could create a lighter weight lens than by using a more expensive higher index material. Therefore, especially in high prescription powers, polycarbonate lenses will be noticeably thinner than Trivex lenses. The one who wins is you. High Index Glass: 1.70: 39: Plastic CR-39: 1.49: 58: Mid Index Plastic: 1.54: 47: Mid Index Plastic: 1.56: 36: High Index Plastic: 1.60: 36: High Index Plastic: 1.66: 32: Trivex: 1.53: 43: Polycarbonate: 1.58: 30: MR-174 1.74 32. High index plastic generally has a lower Abbe number than Trivex, meaning that Trivex is more optically clear and causes less distortion than high index plastic. Log In Sign Up. PLASTIC VS. HI-INDEX LENSES. Good optics are more important to me than cosmetic appeal. They’re more affordable than Trivex and are only moderately heavier. What Index Are High Index Lenses? A long time ago I got glasses from Lenscrafters and I'm pretty sure the lenses were polycarbonate because I noticed a lot of chromatic aberration. With my current glasses, which are high index, I get a lot of chromatic aberration, and I understand this has to … As with PPG Trivex material, you can recommend PPG Tribrid lens material with confidence knowing that this new and unique high-index lens material offers similar performance benefits to Trivex material with enhanced thinness… perfect for your patients with stronger prescriptions requiring more demanding vision correction needs. Indexes of n d values that are ≥ 1.60 can be, often for marketing purposes, referred to as high-index. These lenses are thinner and lighter than CR-39 plastic lenses because they have a higher index of refraction (see below) and may also have a lower specific gravity. 1.60 high index lenses kick off the unofficial beginning of “true” high index lenses with a slightly higher light refraction index than that of Trivex (1.53) and polycarbonate (1.59). Polycarbonate is also even more shatter resistant, making it ideal for activities that have a strong risk of high impacts to your lenses. Posted by 4 years ago. Like polycarbonate it provides 100% UV protection and it is extremely durable. They are as strong, or stronger than polycarbonate for impact resistance. Press question mark to learn the rest of the keyboard shortcuts. When I got new glasses 5 years ago, I specifically asked for Trivex because it's supposed to have low chromatic aberration. We offer a few different indexes on our lenses. If low Abbe value was truly an issue, more people would be wearing glass, with its Abbe of 58.5. I have Been wearing strong glasses for almost 50 years now so 'coke bottle' lenses do not bother me as long as my vision is crisp and clear! Trivex will be thicker than poly or high index north of a +/-5 (I sit at a -375OU and trivex is what cuts out thinnest for me) but it will still have excellent clarity.

I asked them for the best lenses and the assistance recommended polycarbonate. Should I get Trivex lenses or high index lenses. User account menu. The majority of high-index materials have a lower Abbe value, however, meaning that dispersion—when white light is separated into its color components—may be a problem. My RX is -4.25 sphere -0.50 cylinder 176 axis for the right, and -4.75 sphere -0.25 cylinder 4 axis for the left. Therefore, consider this lens for … Glasses become a burden if you are … This test is a requirement for safety lenses. Still, Trivex lenses are thinner than regular plastic eyeglass lenses, which have a refractive index of 1.50. The lower numbers are classified as mid-index lenses. Trivex lenses vs. Polycarbonate Eyeglass Lenses. Trivex is not as thin as high index but it is less dense and so it ought to be less heavy. High Index 1.61, 1.67 and 1.74 All Crystal Vision Lenses are made in the U.S., to exacting specifications, in an Essilor laboratory, and we are able to offer them at a great price point. Thickness: Polycarbonate lenses have a higher index of refraction than Trivex lenses, but not by much (1.58 vs 1.53). Close. Mid-index lenses, such as 1.54, 1.56, and 1.57, are thinner than glass, and nearly as strong as CR-39. High index is thinner compared to other lenses but they don't have better optics. I'd ask for a 1.6 high index lens. the optician recommended zeiss premium progressive high index lenses (1.67 index) for the best optics. Trivex hates to be rolled and polished at all, though, which is a consideration. As for Zeiss lenses, yes they are worth their price, and also their coatings are worth their price. My prescription is -5 sphere -0.50 cylinder axis 104 add +1.25 OD and sphere -5 cylinder 0 axis 0 add +1.25 OS. This allows for a thinner lens than a CR-39 lens. My glasses are 1.61 high index and have fairly serious distortion at the sides. Our 1.6, 1.67, and 1.74 index lenses can all be considered high index. Polycarbonate vs. Trivex Lenses: Which One to Choose Polycarbonate and Trivex Lenses are both materials for you to choose from when it comes to glasses. The lenses are a high-index plastic material.

Join. When I got new glasses 5 years ago, I specifically asked for Trivex because it's supposed to have low chromatic aberration. Mid-index: 1.54 ≤ n d < 1.60; High-index: 1.60 ≤ n d < 1.74; Very high index: 1.76 ≤ n d; This is a general classification. Polycarbonate has a higher index of refraction than Trivex (1.58 vs. 1.53), so polycarbonate lenses are about 10 percent thinner than Trivex lenses. Not sure whether to go with Trivex or Polycarb. ABBE VALUE. Trivex High Index Lenses. I don't think there is a wrong option, but if you have to have your lenses as thin as possible go with high index. It has better impact resistance and naturally blocks UV (granted, most good AR coatings block UV anyway). At a -5 and without knowing specifics of frame tbh I usually use aspheric poly. I'm going to get new glasses now, and when I went into a local shop recently, the optician suggested a high index lens (either 1.6 or 1.67) and said there was no reason to get Trivex, which cost 50% more. Trivex® lenses are impact resistant and more lightweight than standard lenses. Debating on Trivex or high index I have an OD of -8 & OS of -7. High-index plastic lenses. Trivex is a material developed in the 1990s originally for military use. Though it's not guaranteed you'll even notice the difference. Likewise, Trivex and other borderline normal/mid-index materials, may be referred to as mid-index. What type of lens would be better for my RX? Trivex is not as thin as high index but it is less dense and so it ought to be less heavy. Anything Below -2.00 or -.175 Diopters, Doesn’t Require High Index Lenses. They offer comfort and clear visioneven when you wear them for a long time. Though in reality this is not much of an issue, since CR-39 itself is quite impact resistant. Trivex is more impact resistant than high index plastic, making it a much better choice for safety glasses or other types of glasses that need to meet certain impact requirements. Trivex has a lower specific gravity than polycarbonate, making Trivex lenses about 10 … A third benefit of Trivex is its relatively high abbe value. Technology is evolving, and like any new material that appears, trivex lenses bring an addition to the older polycarbonate eyeglass lenses. I know the optical clarity is better in trivex, but I'm concered about the thickness it will have … Press J to jump to the feed. He also recommended an anti-reflective coat ($150 for the higher end coat and $80 for the less expensive coat). Trivex lenses are, molecule for molecule: Eight percent lighter than polycarbonate; 16 percent lighter than CR-39; 19 percent lighter than high-index. Chromatic aberration is when white light is broken up into component colors. Ultra-lightweight—Trivex features the lowest density, 1.11, of any optical-grade material on the market. They can sharpen your sight even further if you apply an anti-glare coati… than ultra high index (1.66 and 1.74) materials. Weight. A color fringe may be noted around a light source or around an object. Depends on what the patient wants from their glasses tbh. Compared with polycarbonate lenses, Trivex® is a premium material that provides crisper vision and is 10% lighter. Their premium coating offers 3 years of warranty normally. So really $180-$250 less expensive depending on the coating. It can also be surfaced down to a center thickness of 1.0mm. Though it's not guaranteed you'll even notice the difference. It has a lower Abbe value, so there will be a lot more chromatic aberration. Anyone who wears glasses knows the difficulty of certain activities is increased because you must keep your glasses on your face while active. Our polycarbonate lenses have a 1.59 index which, while quite thin, is more focused on durability than lightness. Trivex is able to pass the ANSI Z87.1 High Velocity Impact Test. I have had high index a few times and, IMHO, they are no better than poly lenses in terns of the optics. I was taught in school you shouldn’t you trivex above -3 or so.
