With so many choices in lenses, it can be overwhelming to understand all of the options. From standard plastic to polycarbonate lenses and photochromic to hard coat options, we’ve made it easy to discover the benefits of each with our Lens 101 Guide.
Lens Materials :
- Standard Plastic: A popular and affordable lens material, plastic provides lightweight comfort and durability. Coatings may also be applied to prevent scratches and provide UV protection.
- Mid-Index Plastic: If you require a stronger prescription, you may want mid-index plastic lenses, which are thinner and lighter than standard plastic lenses. Photochromic, no-glare coatings, and other protective treatments may also be applied to these lenses.
- Polycarbonate: Another good option for those with stronger prescriptions, polycarbonate lenses are nearly unbreakable, making them ideal for children and those with an active lifestyle. They’re non-distorting, as well as slimmer and lighter than standard plastic lenses.
- Hi-Index Plastic: If you need a stronger prescription and also want extra clear vision, even during extended use, this lens type may be best for you. Like other options, they’re slimmer and lighter, but are usually more expensive. For even sharper vision, especially at night, a no-glare coating can also be applied.
Prescription Types :
- Single Vision: As the name indicates, single vision lenses correct only one sight issue—near vision, intermediate or distance. They can also be used to correct astigmatism.
- Progressives:As you get older, you may suffer from presbyopia, which means you begin to be unable to see well up-close. If you also need corrective lenses for near vision, intermediate or distance, these multifocal lenses may be the answer. Depending on where you look in the lens, these lenses help correct your vision, as needed. Unlike standard bifocals, they have no lines across the lenses and will not cause sudden changes in your vision.
- Bifocals: Also used to treat presbyopia, bifocals (unlike progressives) have a line across the lens, and usually offer a wider viewing area for near vision. Only the bottom portion of the lens is used to correct near vision, while the rest of the lens corrects other sight issues such as distance or intermediate.
Additional Options :
- Photochromic Lenses: Photochromic lenses, also known as light-responsive, will darken when exposed to UV rays or other intense light. When the light is no longer present, the lenses will return to their normal state. An excellent choice for added convenience and UV ray protection, photochromic lenses can be used with most frame styles.
- PureSight Technology: PureSight Technology is an anti-reflective coating that provides clearer vision and a more durable surface. Ideal for when you’re working at a computer or driving at night, this coating minimizes eye fatigue caused by glare and lens reflection. It also resists smudges, dirt and scratches.
- UV Protection: Protect your eyes from harmful UVA and UVB rays with an added UV protective coating.
- Hard Coat + Lens Warranty : Want some additional protection from accidental damage for your lenses? A scratch-resistant lens coating, hard coat, reduces scratching and usual wear and tear on your lenses. Plus, it comes with a two-year lens warranty and unlimited replacement for a 20% copay of retail charge.
- Tint: For sunglasses, cosmetic appeal, and special usages, tinted or colored lenses minimize unwanted glare. Important to note, tinted lenses may slightly alter the colors you see.
- Roll & Polish: Ideal for rimless frames and stronger prescriptions, the Roll & Polish option makes the edges of a lens thinner by grinding down part of it.
- Polarized Lenses: Polarized lenses improve visibility and minimize eye fatigue by reducing glare from water, snow, glass, and roads. They’re perfect for outdoor activities like fishing and snow skiing, as well as driving. Important to note, they may change your visibility of images on an LCD screen.
