Most modern lenses are created using plastic, as it is lighter than glass and at a more affordable price point. Plastic can be easily moulded to create lenses that work with your frames, and they are more break-resistant and shatter-proof than glass. Plastic lenses are ideal for children’s glasses or if you want to protect your eyes from splinters or sparks while working and are the most popular type of lenses that you will typically see other people wearing. You can add plastic lenses to any kind of frames, including rimless and full frames.
Polycarbonate lenses are more resilient than their traditional plastic counterparts, as well as being more lightweight and thinner. This type of plastic was originally used for astronaut’s helmet visors before being used for consumer eyewear. These lenses have an ultraviolet protection aspect, to protect your eyes from the sun’s rays and other harmful environmental factors. Polycarbonate lenses are an ideal choice of lenses for children’s glasses, or adult’s glasses if you intend to wear them while playing sports. Polycarbonate is up to ten times stronger than traditional plastic and is comfortable enough to be worn all day long.
Trivex lenses are similar to polycarbonate lenses as they are both resilient and lightweight. The main difference between trivex lenses and polycarbonate lenses is that the former gives you a higher-quality of vision. As trivex is a more resilient material than traditional plastic, it is an ideal choice for glasses that are rimless or if you need something that is more impact resistant. Trivex is a newer material that is used for lenses, and in some cases, they can do a better job of correcting your vision than traditional lenses.
High Index 1.67
High Index lenses are created using a plastic that refracts light better than traditional plastic lenses. These lenses are thinner as they require less plastic and they are graded with numbers, with the higher of the High Index numbers using less material. If your prescription is extremely strong, then opting for a High Index lens is one way to make them appear more aesthetically pleasing as they suit modern frames better than thicker plastic lenses. High-index lenses come with a refractive index in the range of between 1.53 to 1.74. Our High Index 1.67 sits comfortably in the middle of this range.
High Index 1.74
High Index lenses are ideal for those with a stronger prescription as they require less plastic than other kinds of lenses. The High Index 1.74 lenses are thinner than their High Index 1.67 counterpart, giving you the lightest weight option, which works best with thin frames. If you are considering a modern style of frames, and have a higher prescription level, then we recommend investing in these lenses to get the most seamless look for your glasses, as they are 50% tinnier than traditional plastic.
