Glasses

What lens types are used in glasses? 

All prescription eyeglasses are made with one of two basic lens types: single vision lenses or multifocal lenses. Prescription sunglasses, which provide 100% protection against harmful ultraviolet (UV) radiation, can be made with any lens type. 

Single vision lenses are simple, all-purpose lenses designed to correct distance vision, while multifocal lenses are a type of dual-purpose lens used to correct distance vision as well as near vision. Your personal prescription determines which type of lens you need to see clearly. 

If you require multifocal lenses, your prescription specifies which type: 

Bifocals

The bottom half of these specialized lenses contains a correction for reading and close vision, while the top half is designed to correct distance vision. 

Double-D bifocals are similar to bifocals, but have an added area of correction for up-close vision at the top of each lens; these lenses are ideal for people who often need to look up at nearby objects. 

Trifocals

Trifocal lenses are made with three distinct areas of correction — one for near vision at the bottom, one for intermediate vision in the middle, and one for distance vision at the top.  

How do progressive lenses work?

Also called “no-line” lenses, progressive lenses are bifocal or trifocal lenses that are made without visible dividing lines between each distinct focal area. Instead, they have a precisely graduated, smooth transition between near vision and distance vision focal areas. 

Many people find progressive lenses easier to wear and more aesthetically pleasing than traditionally divided lenses, but for some people, the larger transitional areas on progressive lenses can be somewhat distorting.  

What are the benefits of different frame materials?

Glasses frames are available in a wide range of metal and plastic materials, each of which comes with its own set of benefits and drawbacks. Although frame style is a top consideration for most people, the material you choose is what helps determine how comfortable they are and even how long they may last. 

Metal frames

Modern metal glasses tend to be lightweight, sturdy, and corrosion-resistant. Hypoallergenic titanium frames are available in a wide range of colors and stand up well to excessive wear-and-tear. Beryllium frames are strong, flexible, and easy to re-adjust after an accidental bending. Aluminum, stainless steel, and Flexon are other good choices.  

Plastic frames

Plastic frames are generally more popular than metal frames because they tend to be less expensive, and they’re available in a wide range of styles and colors. Although plastic frames aren’t usually as strong as metal frames, they can last for many years with the right care. 

Zyl, or cellulose acetate, is super lightweight and easy to adjust, while cellulose acetate propionate frames are hypoallergenic. Blended nylon is often the go-to material for sports frames or wraparound-style eyeglasses and sunglasses.
