Frame Only
In order to add any lens options, you must select a Lens Type OTHER than "Frame Only".
Single Vision
Single vision occurs when an individual is near sighted or far sighted, but not near sighted and far sighted.
Digital Single Vision
Digital Single Vision lenses are fabricated based on the wearer’s prescription with computer-controlled surfacing equipment that is much more precise than conventional tools. Digital lenses fabrication technology allows for surfacing of lenses in power increments of 0.01 diopter, compared with 0.125 to 0.25 diopter increments possible with traditional eyeglass lens tooling.
BiFocal
A lens with two points of focus - usually one for distance and one for near vision. Bifocal portion of lens is in the shape of a half moon.
Progressive BiFocal
A no-line multi-focal lens that includes all corrections, from distance to close-up, in one lens without any separation of the visual zones by a line.
Lined Trifocals
A lined multi-focal lens that includes all corrections, from distance to close-up, in one lens.
Polycarbonate
Polycarbonate (often called “poly”) is a popular material used for eyeglass lenses. It’s lightweight, strong, and impact-resistant, making it great for safety glasses or for people who are active. Polycarbonate lenses have a thinner profile compared to regular plastic lenses because they have a higher index of refraction, which means they can bend light more efficiently. The index of polycarbonate is 1.59, which allows for thinner lenses even with stronger prescriptions. (Abbe Value 30)
Trivex
Trivex is a type of lens material that’s similar to polycarbonate but has some added benefits. Like polycarbonate, Trivex lenses are lightweight, strong, and impact-resistant, making them great for active people or for use in safety glasses. What sets Trivex apart is that it provides even clearer vision because of its higher optical quality. It also has a slightly lower index of refraction (1.53), meaning the lenses may be a little thicker than polycarbonate, but they’re still very light and comfortable to wear. (Abbe Value 44)
1.67 High Index Plastic
High index 1.67 plastic lenses are a type of eyeglass lens designed for people with stronger prescriptions. These lenses are thinner and lighter than regular lenses because they have a higher index of refraction (1.67), which means they bend light more efficiently. Even if you need a strong prescription, 1.67 high index lenses help reduce the thickness and weight, making your glasses more comfortable and less bulky. They are available in a wide array of lens types and other special coatings. We highly recommend purchasing an Anti Reflective coating with the high index lenses since they reflect a considerably higher percentage of light than standard lenses. (Abbe Value 32).
1.74 High Index Plastic
1.74 High Index lenses represent the highest index available in plastic lenses, and they’re an excellent choice if you’re aiming to minimize lens thickness for stronger prescriptions. They’re particularly beneficial for individuals with prescriptions over +/-8 or with high cylinder corrections. Additionally, if you’re drawn to larger frame styles, 1.74 lenses will help reduce the added thickness that often accompanies higher prescriptions in bigger frames. This makes your glasses look less bulky and more comfortable to wear, even with a high prescription. High index 1.74 lenses are perfect for anyone looking for a sleek, lightweight option with strong vision correction. We highly recommend purchasing an Anti Reflective coating with the high index lenses since they reflect a considerably higher percentage of light than standard lenses. (Abbe Value 33).
High Index Plastic Final Thoughts
In a nutshell, if you have a prescription below a -3, there isn’t really any reason to invest in high-index glasses because they won’t look any different to the human eye and there won’t be any real benefit to the higher-index lens. The standard lenses have a higher Abbe value, so the quality of vision will be far superior. The difference between 1.67, which is considered regular index and 1.74 is quite small, and really, the only way you’ll notice the difference is if you have a prescription below a -6 or above a +4.
However, if you are in need of a very strong prescription, it is absolutely worth the additional cost! Your glasses will be more comfortable and more flattering, and that will improve your quality of life overall.
Standard Glass
Standard glass lenses are known for their excellent optical quality and scratch resistance. Because glass naturally has a high level of clarity, these lenses offer sharp, clear vision. Glass lenses are also highly resistant to scratches, making them a durable choice that can maintain their quality over time. However, one downside is that glass lenses are heavier than plastic or other modern materials, which can make them less comfortable for all-day wear, especially in stronger prescriptions. Despite their weight, glass lenses remain a great option for those prioritizing durability and top-notch optical clarity. (Abbe Value 59)
1.60 High Index Glass
1.60 High Index glass lenses will be an excellent option for mid-strength or ordinary eyeglasses prescriptions. The 1.60 glass lenses are thinner than standard 1.523 glass lenses and still offer High Optical quality and scratch resistance. These lenses make a great option if you value a thinner look and lightweight comfort in your eyewear. (Abbe value 44)
1.70 High Index Glass
1.70 High Index glass lenses will be an excellent option for mid-strength or high eyeglasses prescriptions. The 1.70 glass lenses are thinner than standard 1.523 or 1.60 glass lenses and still offer the Highest Optical quality and scratch resistance. These lenses make a great option if you value a thin look and lightweight comfort in your eyewear. (Abbe value 39).
High Index Glass Facts
Eye prescriptions below +/-4.00 can benefit from our standard 1.53 or 1.60 lenses. We recommend 1.70 or 1.80 high-index lenses for people with prescriptions between +/-4.00 and +/-8.00, and 1.80 & 1.90 high-index lenses for people with prescriptions +/-8.00 and higher. We highly recommend purchasing an Anti Reflective coating with the high index lenses since they reflect a considerably higher percentage of light than standard lenses.
The positive qualities of high index lenses apply to a large group of corrective eye-wear consumers but not to all. If your prescription is a relatively weak one, the weight and thickness variations between standard lenses and high index lenses would not vary all that much. If high index lenses cannot offer you a noticeable reduction in thickness or increase in appearance, they may not be worth the higher cost to you. The standard lenses offer offer a much higher Abbe value, so the lenses will be superior in vision quality than the high index lenses. The high index lenses are also dense, so they will have added weight.
1.80 High Index Glass
1.80 High Index glass lenses will be an excellent option for high to very-high eyeglasses prescriptions. The 1.80 glass lenses are thinner than standard 1.523, 1.60, and 1.70 glass lenses and still offer the Highest Optical quality and scratch resistance. These lenses make a great option if you value a thin look and lightweight comfort in your eyewear. If you purchase 1.80 High index lenses, you add an Anti-Reflective Coating to reduce glare.

1.90 High Index Glass
High Index 1.90 Glass lenses are for the strongest prescriptions and are only available for eyeglasses. If your Prescription is not higher than a -8.00 or a +6.00 1.90, lenses are not for you. 1.90 Lenses are the Highest index lenses offered on the market. We Only Recommend 1.90 glass lenses for frames with small lenses to reduce the weight of your glasses because we've found that overall eyeglass weight plays a significant role in overall comfort.

Scratch Coating
A scratch resistant coating is often applied to surfaces that are not inherently scratch-resistant, like CR-39 plastic, polycarbonate, or Trivex. It adds a barrier of protection that hardens the surface against both large gouges and smaller scratches, which can build up and crisscross to add a hazy appearance to lenses. If your lenses are formed from any material other than glass, a scratch-resistant coating will increase their productive lifespan.

UV (Ultra-Violet) Protection Coating
UV light is invisible to the human eye but can, in excess, cause retinal burning and scarring. Most sunglasses are already designed to block a high level of UV radiation; other lenses, depending on their function or lens material, may also block some UV rays. If your lenses do not specifically state their UV screening level and you spend time outdoors, an additional UV coating will offer protection and peace of mind. Anti-UV treatment is not necessary on polycarbonate lenses because it is an inherent property of the material.
Price: $50.00
Anti-Fog Coating
An anti-fog coating works by chemically affecting the adhesion of water molecules, preventing them grouping into larger clusters that can impair vision. If your glasses are frequently exposed to temperature changes or humid conditions, you’ll likely want an anti-fog coating to help combat condensation. The same goes for anyone who engages in strenuous activities such as physical labor, participation in sports, or exercise. Any activity that causes your body temperature to fluctuate will likely lead to lens fogging.
AR (Anti-Reflective) Coating
Anti-reflective coatings eliminate the distracting glare that can be produced by light when it reflects through your lenses. Anyone subjected to direct or indirect reflections – especially those who spend a lot of time around computers and electronic monitors of any type, suffer from eye strain, or who drive at night – will likely enjoy the benefits of glare reduction. Due to the high reflective properties of high index lenses, an anti-reflective coating is recommended, and is practically mandatory for high index lenses made of glass. (Note: AR coating is not good for outside glasses, dusty dirty environments and or constant cleaning.) The lenses must be wet before they are cleaned.
Anti-Reflective with Blue Blocker Coating
Blue Light Plus AR coating is applied in a vacuum coater. The recipe contains anti-static layers, as well as an oleophobic layer to make the glasses easy to clean and stay smudge free. The Blue Light protection is applied to the front side of lens for protection from HEV at 440-480nm. A blue hued AR stack is also applied to the backside of the lens for maximum glare reduction. The coating’s blue hue makes the lenses more attractive.
These lenses will have a light YELLOWISH tint. If you are looking for a virtually clear lens, order the Blue Blocker with Clear Lens Tint and our standard Anti-Reflective (AR) coating.
