Different types of nose pads for glasses

The fixed nose pad is usually used on the plate frame. The nose pad and the frame form an organic whole. The maintenance is more convenient, unlike the movable type that should often twist a screw. It is not easy to hide dirt and dirt. But the disadvantage is that the angle of the nose pad can not be adjusted, and it can not fit the bridge of the nose greatly. The movable nose pad can be automatically adjusted up and down according to the shape of the bridge of the nose to ensure that the compression part of the bridge of the nose is evenly stressed and the local pressure is reduced. But the disadvantage is to often check the tightness of the screw, but often scrub clean. The silicone material usually used in the nose pad is easy to yellow after a long time, which affects the appearance.

Can You Wear Glasses Without Prescription?

Polarized vs non-polarized sunglasses

1. Non-polarized sunglasses generally only have the two basic functions of shielding strong light and filtering ultraviolet rays, and their efficiency in filtering ultraviolet rays is low. In our daily life, in addition to strong light and ultraviolet light, when light passes through uneven roads, water surfaces, and other places, irregular diffuse reflection light will be generated, which will cause blurred vision and fatigue in the eyes.

2. Polarized sunglasses can filter out this kind of light, only absorb the reflected light of the object itself, truly present what you see, make the field of vision clearer, and reduce visual fatigue. In addition, polarized sunglasses have a 99% blocking rate of ultraviolet rays due to their high-efficiency filter layer, which can effectively reduce the damage of ultraviolet rays to the eyes.

3. When judging whether the sunglasses are polarized lenses, you can rotate the sunglasses up to 45° clockwise. If the color of the lens changes at this time, and the color of the sunglasses returns to normal after turning the sunglasses back to the original position, then it can be judged that the sunglasses are polarized. And if you can’t see the change in the color of the sunglasses lens no matter how you turn it, then you can judge that the sunglasses are not polarized.
