Precautions for purchasing bicycle sports glasses

A good pair of bicycle glasses should not only have PL lenses (polarizers), but more importantly, the weight of the lenses and frame, and the design between the bridge of the nose and the brow bone. When riding, the speed is fast, so the bridge of the nose must be well supported, so that it will not slide due to vibration. The design of the upper edge of the brow bone is also very particular, so that sweat cannot flow down the frame to the lens. The breathability of the lens is very important for cycling. The   fast-moving air will take away the moisture and will not fog up the glasses. The material structure of the lens itself is the most important. In addition to the PL function, it is   very important to use PC lenses for bicycle lenses. It will not break when the lens is subjected to a strong impact, and will not produce damage to the eyes. Chips, its   strength is also unmatched by ordinary lenses.

There are strict technical indicators and differences between foreign leisure glasses and bicycle sports glasses.

Generally, glasses that are truly suitable for cycling must meet the following elements:

1. UV function: UV400

2. Portable and ergonomic design

3. Lens material requirements (whether PC lens or not)

4. The effect of eliminating stray light (PL technology)

5. Air permeability of the lens

6. Safety (the minimum requirement is that a 0.5-pound steel ball falling from a height of one meter and hitting the lens cannot cause rupture)
