FRAMES

Different eyeglass frame materials expand your options for a new look and comfort. Our opticians can help you to find eyeglasses with qualities that are important to you. There are three basic categories of the materials for frames and each has its own unique strengths.

Plastic Frames

Another name for plastic frames is zyl, zylonite, or cellulose. Zyl is a very cost effective and creative option for eyewear and is lightweight. If you want a variety of colors for your frame then zyl is your material.

Another plastic based material is cellulose acetate propionate which is hypoallergenic. It is extremely lightweight and has more transparency and gloss than other plastics.

Nylon is also a premier material for plastic frames. It is typically made of gliamides. Nylon frames are very resistant to hot and cold and are more flexible, yet very stiff. The today’s wrap around frames as well as other shapes that are difficult to produce are made of nylon.

Metal Frames

Monel is the most widely used material in the manufacturing of metal frames. It is resistant to corrosion.

Titanium and Beta- titanium material is used to add lightweight durability and strength to metal frames. Titanium eyewear can be produced in a variety of looks with a hint of color. Titanium and Beta are hypoallergenic. Titanium can be combined with other material, such as nickel and copper, to reduce the cost. Another metal based frame material is Beryllium, a steel gray metal. It is a lower cost alternative to titanium eyewear. It resists corrosion and tarnish making an excellent choice for people who have high skin acidity or spend a lot of time around salt water. It comes in a variety of colors and is very flexible.

Flexon is a titanium based alloy. The unique feature of this material is that it wants to keep its shape. Marchon was the first to manufacture flexon eyewear, which are sometimes called memory metal frames, because after twisting, bending, and crushing the frames return to their original shape. They are an excellent choice for children.

Stainless steel frames are another category of metal frames. It is an alloy of steel and chromium. Stainless steel frames are lightweight and nickel free making it a good choice for people with allergies.

The last metal based eyewear is made of aluminum. These frames are lightweight and highly resistant to corrosion. Aluminum is used primarily in high end eyewear.

Other

Some very expensive frames are made of wood, bone, buffalo horn, gold, or silver. They are handmade and each frame is unique and one-of-a-kind.

EYEGLASS LENSES

High-Index Lenses - High-Index material offers superior optics in a thinner,
lighter lens.

Polycarbonate Lenses - Polycarbonate lenses are very impact resistant. They are great for children, sports and safety glasses.

Regular Plastic (CR-39) - CR-39 is the basic lens with good optics. They are a very good option for lower prescriptions and are lightweight.

Glass Lenses - Glass lenses provide excellent optics. They are heavier than plastic lenses but extremely resistant to scratches.

Multifocal lenses - Multifocal lenses come in a variety of forms depending on your activities. They can be lined, such as bifocal or trifocal, or without lines such as progressive lenses. There are a lot of improvements made with the progressive lenses to make them more adaptable. The new generations of progressive lenses are called free-forms, which provide excellent distance, near, and intermediate vision.

Wave-front Lenses - Wave-front lenses can correct higher order aberrations which result in better vision, especially at night.

Transition and Photo-Gray Lenses - Transition and photo-gray lenses lighten and darker quicker. There are also drive-wear transition lenses that are polarized.
