SPECTACLE AND PRESCRIPTION SUNGLASS LENSES
Types of Prescription Lenses
These lenses were designed for individuals who either have myopia (near-sightedness) or hypermetropia (long-sightedness). It is designed to serve a single prescription and will assist the user in seeing both distance and near objects
These lenses are designed to solve problems for people who have multifocal limitations. The inability to see both distance and near objects without using 2 to 3 different powers for the same. Progressive lenses have different focal points in a single lens to help the wearer see distance, intermediate and near vision clearly.
These lenses are designed to help the wearer see two visual zones clearly having two different prescriptions : one for distance and another for reading. Bifocal lenses are available in different designs with two segments : a half moon or an inverted D or a no line bifocal (new) for the reading segment and the rest of the lens is for distance.
Brands that We Dispense
We retail several brands like Zeiss, Hoya, Nikon, Essilor, Nova and Rodenstock in prescription lenses for both clear eyeglasses, photo-chromatic and sunglasses. Depending on the prescription and the type of correction required, we dispense the following lenses.
To know which lens is best suited for your needs please consult our team at the store.
Materials that We Recommend
The materials used in making prescription eyeglasses vary based on the power and its purpose. For example, prescription lenses for sunglasses are available only in certain types of materials while clear and photochromic lenses will be available in almost all materials. We choose to dispense lenses only from tried and tested companies; those that spend significantly on research and design, keeping the end wearer in mind. Corrective eyeglasses are important and compromise will not help your vision leading to other problems.
What are Columbia Resin 39 or CR-39 lenses?
CR-39, or allyl diglycol carbonate (ADC), is a plastic polymer commonly used in the manufacture of eyeglass lenses. The abbreviation stands for "Columbia Resin #39", which was the 39th formula of a thermosetting plastic developed by the Columbia Resins project in 1940. Source : Wikipedia
CR-39 material is used to manufacture lenses with indices of 1.50 and 1.56. This material is best suited for low powered prescription lenses. CR-39 is not as strong as MR or Polycarbonate lenses, but visual clarity is much better than polycarbonate lenses.
Companies that use this material are Carl Zeiss, Nikon, Nova, Rodenstock and Essilor.
What are Mitsui Resin or MR lenses?
MR™ lens materials are made from thiourethane resin, a material that provides great lens properties. These lenses provide numerous characteristics, among them clarity, safety, durability, and refractive index. They are available in high indices such as 1.60, 1.67 and 1.74 and are the most widely sought after lenses in the world. They are best suited for prescriptions that have high powers.
Companies that use this material are Carl Zeiss, Nikon, Nova, Rodenstock and Essilor.
What are Polycarbonate lenses?
Polycarbonate lenses are best suited for rimless frames due to its strength and higher resistance to breakage. It is available in a single index of 1.59 and is available in all lens portfolios. It is best suited for low and mid range powered prescription lenses
Companies that use this material are Carl Zeiss, Nikon, Nova, Rodenstock and Essilor.
What are Trivex lenses?
Trivex lenses rival polycarbonate lenses as the safest lenses on the market. It’s made of an exceptionally clear, lightweight lens material, which finally translates into excellent all-day wearing comfort. These lenses are unbreakable and come with a lifetime warranty on breakage. They are available in limited supply and are best suited for low to low-mid range powers in prescription for eyeglasses.
Only one company uses this material in dispensing, called Nova.
What are Glass lenses?
Glass lenses are the earliest material used in correcting vision problems. However the limitations with glass is its weight and ease in breakage putting the eye at great risk. As such materials evolved over time to create a blend of glass and resin in order to use the best properties of both materials. You will find such blends in the lenses provided by Maui Jim sunglasses.
Glass provides great optical clarity; the best when compared to other substitutes available in the market. Today, glass is used rarely and most companies have stopped using it as the base for optical lens production.
Companies that still continue to manufacture glass lenses are Rodenstock, Vision Rx, Maui Jim(blended) and Ray-Ban.
