Eyeglass Material
When choosing eyewear, it's important to consider the material of the eyeglass frames. Certain materials might better suit your lifestyle or personality. Materials also can affect the weight, style, comfort, quality, and price of your glasses
Plastic:
Plastic is a great material for frames because it comes in a variety of colors, textures, and patterns. The adjustability of plastic eyewear depends on the type of plastic used. Some are easy to adjust with little or no heat, while others are durable, impact-resistant, and great for sports. Some plastics can become brittle or discolored with age, so use caution and make sure you're buying a quality plastic
Metal:
Metal frames are lightweight, strong, and hold their shape well. They also can be made in or coated in various colors. Some people are allergic to certain metals; if this is you, try hypoallergenic options such as titanium
Titanium:
Of all metals, titanium is one of the best frame materials available. It's lightweight, durable, and corrosion-resistant. Titanium also is hypoallergenic—so it's a great choice for people who are allergic to other metals. Titanium is strong, easy to adjust, and comes in an array of colors. Titanium eyeglasses are great for hot, humid environments because of their strength. Titanium eyeglasses are perfect for active lifestyles or those with prescriptions that require thicker lenses
