                               Types of Frames


Plastic frames - very stylish, classy and professional, or just plain fun. They are also ideal for high prescription powers because they can more easily hide lens thickness. Plastic frames are great for those people who have a skin reaction to certain metals.
Titanium frames - very strong, but lightweight. Available in designs that can be twisted and spring back into shape when released. Titanium frames are also ideal for those people who have a skin reaction to certain metal frames.
Semi-rimless frames - frames that have usually metal across the top of the lens and a wire that holds the lens in place from underneath. There are excellent styles for both men and women.

What type of lenses do you need?



You can spend a lot of time picking out the right frame, but if you don't get the right lenses, you can be missing out on clear, comfortable vision. Listed below are lens materials and options to help you understand and decide which is best for your lifestyle.



Lens Materials


• CR-39 – these basic plastic lenses are more easily scratched than glass and do not block out harmful UV rays. Application of a scratch-resistant and UV coating are recommended.
• Polycarbonate – these lenses are impact resistant and are highly recommended for children and active patients. The material weighs less than CR-39 and, because of it's strength, can be made ultra-thin, allowing for more lightweight and comfortable lenses. Another benefit to these lenses: they block harmful UV rays.
• High Index – these lenses bend light more efficiently than CR-39 so they allow stronger prescriptions to be made thinner and lighter. In some instances, high index materials provide better optics than polycarbonate.
• Trivex - these are impact resistant and the most lightweight of all lens materials, but not necessarily the thinnest.
• Glass – glass lenses are very heavy and rarely used.



Lens Designs


• Single Vision – single vision lenses can provide clear vision at all distances providing a bifocal prescription is not required (usually for those under age 40). If a bifocal prescription is needed, single vision glasses can be used in task specific instances to clear far, intermediate, or near visual demands.
• Flat-top Bifocal (or Trifocal) – bifocal lenses provide distance vision in the top portion and near vision in the bottom. These lenses are not recommended for patients that need clear intermediate vision, particularly those who use computers regularly. A trifocal offers distance, intermediate, and near focus with visible lines between each segment.
• Progressive – progressive lenses are the most advanced multi-focal lens available. These lenses provide continuous clear vision at all distances without visible lines. There are many brands of progressive lenses available from low to high quality. The highest quality progressive lenses offer the least amount of distortion and the clearest image to the wearer. There are progressive lenses that are custom made to the frame you choose and how that particular frame fits on your face, so the lenses adapt themselves to you instead of the other way around!
• Computer lenses – for people that are on the computer for many hours per day and wish to have a wider field of view than is found in progressive lenses, these lenses are a perfect option. These lenses provide a wide corridor for both intermediate and near vision. Some even have a small area at the top for distance vision.
• Anti-reflective coat – all 'lenses' create reflections when they are untreated. This is why you can see a trace reflection of yourself when you look into a car or house window. If those windows were treated with anti-reflective coating, you would not have to cup your hands around your eyes in order to see inside. With this coating, distracting reflections are removed from the front and back surfaces of the lenses. This improves the quality and clarity of vision, reduces eye-strain and also enhances the wearer's appearance. Anti-reflective coatings are commonly recommended for patients with night-vision complaints and computer users as the coating reduces glare.
• Photochromic – also called "Transitions" because of the well known brand, these lenses are clear when indoors, but darken when outdoors. The brighter the sun, the darker they become. These lenses provide 100% UV protection. As they are triggered by UV exposure, they will only darken in direct sunlight, and they do not darken when inside a car.
• Polarized lenses – polarized sunglasses are the optimal lenses for outdoor use. They eliminate glare reflected off the surface of objects such as a wet road, the water when fishing, or snow when skiing. These lenses provide more comfortable and clear vision than is available with a simple tint.
• Scratch-coat – scratch-resistant coating protects lenses from normal scratching during everyday use. "TD2" is a more advanced scratch protection that coats both sides of the lens and is a valuable option for children and adults that are rough with their glasses.
• UV filter – CR-39 lenses do not protect against UV unless this coating is added. This is important in any climate, but especially here in Florida.
• Aspheric lenses – aspheric lenses allow for improved vision and more attractive glasses in higher prescription powers. They reduce peripheral blur and create a flatter, thinner and lighter lens. For people that are quite nearsighted, they reduce the small eye appearance; and for people that are farsighted, they reduce the bulgy, enlarged eye appearance.
