Foam-back glasses are convenient and provide adequate protection. Protection eyeglasses should be manufactured with strict fitness and large lenses.

Clip-on glasses are popular nowadays. The clip should fit the edges of the glass properly and be close to the lens. In most cases, clip-on glasses need additional adjustments at the time of purchase. There are also colored lenses that offer both good look and great functionality.

Smoked lenses feature convenience and extended durability. While filtering out blue light, amber lenses always provide sharp contrast and sharp shadow definition even in over-cast conditions. Yellow lenses are particularly suitable for night driving, as well as in conditions of snow and fog. Clear lenses can provide ample UV protection and suit conditions with low light.

Another particular type of lenses is photochromic lenses, which are commonly used in conditions of varying light. Polarized lenses are designed to fight against high glare, which protects the eyes form sudden flashes of light thus avoid potential retina damage. Reflective lenses can reflect the light away from the eyes, relaxing the eyes and reducing eye stress.

Besides of the functions from those various eyeglass lenses, some people also resort to eyeglasses for fashion.

In addition, the materials of eyeglasses frames are also worth customer’s attention. A strong steel frame is suitable for a businessman, while sportier people always choose a light titanium frame.
