Can Blue Light Glasses Cause Headaches?

The Disadvantages of Polycarbonate Lens

In this section, we will show you the disadvantages of polycarbonate glasses.

First, the polycarbonate lens is expensive than other regular lenses. It can cost up to double the price of regular eyeglasses.

Second, compared with high-index lenses, polycarbonate glasses have a lower abbe value, which is used to measure the dispersion of light for different eyeglasses lens materials. Polycarbonate lens rates lower mean they have the potential to cause slight chromatic aberrations in your peripheral vision.

Third, compared with Trivex lens, polycarbonate lens has bad durability since they are thinner and lighter.

Phone can identify polarized sunglasses.

Take a mobile phone with an LCD screen, turn it to maximum brightness, and look at the LCD screen through the lenses. Make sure the lenses are parallel to the display, and then slowly rotate the phone. When the true polarized lens is rotated at a certain angle, the light from the display becomes obviously darker, or even pitch-black. If they're not dark, they're not polarized sunglasses.


Clean your glasses correctly.

The dust of the lens will be washed (lightly), and then use a neutral detergent (cleaner) to clean. You can also buy professional glasses cleaning fluid, finally clean by water, and then use a professional glasses cloth to wipe. If the lens is covered with dust and particles before wiping, it is best to wash it with water and then gently dry it with a cloth.

How ro Determine Your Face Shape

When you choose sunglasses, it is important for you to understand your face shape. The basic principle of choosing sunglasses is that you cannot wear round glasses with round faces, and square glasses with square faces. Otherwise, round glasses make faces rounder and square glasses make faces more square. The heart-shaped face can be worn in all shapes of glasses. For the oval face, which is a standard face, just don't choose an overly exaggerated shape when choosing sunglasses. Choose sunglasses as far as possible to avoid being too fancy because the fancy sunglasses will make you look very lackluster.
