Lens Materials
- Plastic : Conventional hard resin lenses are half the weight of glass lenses and can be either clear or tinted to almost any color.
- Hi-Index : Modern technology has created lenses that bend light differently so that stronger corrections are thinner than when made in conventional plastic materials
- Polycarbonate : This is the lens of choice for young people, anyone concerned with safety and sports eyewear because it is the most impact resistant lens available. People with Higher plus or Higher Minus Prescriptions tend to prefer this lens, because it allows the lens to be much thinner and lighter than conventional Plastic.
- Trivex : This is the world's first tri-performance lens material; meaning it offers a triple combination of features never before found in a single material. Superior Optics. Impact Resistance. Ultra light Weight. This breakthrough in technology is specifically designed to deliver the most comprehensive performance of any lens material, anywhere.
- Single Vision: Most appropriate when correction is needed for only one distance or only one power is needed to see clearly at all distances
- Bifocal : Bifocals provide correction in 2 powers - distance & near. Bifocals are necessary when a single vision lens no longer provides the best vision at all distances.
- Trifocal: Trifocals provide correction for 3 powers - distance, intermediate & near. As the need for stronger reading lenses progresses, a gap develops between the distance and near clear zones of a bifocal causing blurred vision at arms length. A trifocal can provide correction for reading and an intermediate zone. While not as continuous as a progressive lens design, a trifocal does provide clarity beyond the reading distance out to approximately 3 feet. (Depending upon prescription)
- Progressive: Most beneficial when you need a different prescription for multiple focuses. A progressive lens contains no line; instead, there is a gradual change of power along a “channel” from distance to near.
- Computer Lenses: Extensive computer use requires correction for the computer distance in the straight ahead position of the lens (so you do not have to tilt back and strain your neck in order to see clearly at that working distance). Computer lenses are designed to provide computer correction in the middle of the lens with reading below and distance correction in the upper portion of the lens so you can look up and see clearly across the room.
- Scratch Resistant Coating As plastic is a softer material then glass, a coating is provided to help resist scratches. This special coating can help protect your lenses from any scratches that may occur through out the day.
- Anti-Reflection Coating Anti-reflective coating is particularly effective for reducing eye fatigue from computers, night driving and fluorescent lights that cause glare. This also enhances the appearance of the lens and glasses by removing all distracting reflections from the lens surface.
- Polarized Sun Lenses Polarized lenses eliminate reflected glare from surfaces illuminated by bright sunlight. They are great for driving, fishing, hunting, and all types of outdoor activities. They are available in many different colors.
- Transitions Lenses Change from clear to dark in the presence of ultraviolet light, and block 100% of harmful UV rays. The innovative photochromic technologies have produced unparalleled lens performance in nearly every lens design and material, including shatter-resistant lenses, bifocals, trifocals, progressives, and standard and high index materials.
