Why Are Ski Goggles Yellow?

Driving Sunglasses Brands

Ray-Ban polarized sunglasses

Polarized sunglasses filter polarized light. If the lenses are in dark colors (such as tan, green-gray, etc.), they are more comfortable to wear in summer. Polarized lenses are globally recognized as the most suitable lenses for driving. Glare is caused by light that is partially polarized when reflected off an object's surface. The adverse effect of glare- is to enhance brightness and reduce color saturation. It outlines the object becomes blurred and the eyes become tired, uncomfortable. A polarized lens is made according to the principle of the polarization of light, which has the special function of effectively eliminating glare, filtering the disordered light, so that the driver can improve vision and add fun to driving.

Features of Beta titanium glasses frame

Beta titanium has better strength, fatigue resistance, and environmental corrosion resistance than pure titanium and other titanium alloys. The shape plasticity is very good, which can be made into wire and sheet, more lightweight. They are used to make glasses and can get more shapes and styles. It's the material for a new generation of glasses. Customers with higher requirements for style and weight can completely choose beta-titanium glasses. Because β titanium processing technology is higher than pure titanium, usually only large factories and brands will produce, and the price is higher than pure titanium glasses.



What are the causes of lens damage?

When the force area of the lens is small, the impact resistance of the lens is worse. When subjected to the impact of external forces, the lens will naturally be squeezed and cause breakage.

In particular, some lenses with low degrees and high refractive index are possible to cause this phenomenon. When the frame fell from a height due to wrong placement, there is a collision between the edge of the lens and the ground or hard objects. It will produce a broken or collapsed edge. In the process of the lens falling from high, the impact force is larger, and the stress point is smaller. When the glasses are falling, the upper edge of the lens, the convex groove of the upper frame, squeezes against the lens. The middle part of the upper half is easy to cause edge collapse. In the process of processing the template, the template is not accurate, so that the glasses side and the frame can not be uniform fusion, and the force of the lens is uneven. It will be easy to lead to greater stress in some parts, resulting in edge collapse.


Adjustment of the angle of the nose pad

For the angle of the nose pad, you can apply torque in the horizontal or vertical direction according to the deformation needs. It can be held in the proper part of the nose pad with needle-nose pliers, and the torque can be applied at a certain angle in the vertical plane or horizontal plane to achieve the purpose in accordance with the deformation needs. In the time of repeated actions, in order to prevent the welding place of the nose pad and the glasses ring from breaking due to repeated stress deformation, you can use your fingers to apply external force at the welding place to change the deformation position and play the purpose of protection.



Type of eyeglasses cloth

There are many kinds of cloth for glasses. There is mainly sheepskin eyewear cloth, and there is microfiber eyewear cloth. There are suede and double-sided cloth and so on. Professional eyewear cloth must use more than 200 grams of weight/per cubic centimeter of microfiber. This kind of raw material chemical fiber is fine, and tactility is soft, so it will not damage the lens. This kind of wipe cloth can be used on a computer screen. The two sides of the cloth are different, and the smooth side is used to scrub the lenses. Because the dirt on the lens is mostly small. The rough side is designed to give you more friction when you touch it with your finger, so you can use it more easily, and you can clean it more.

The Identification of the Quality

The frame that has good elasticity is usually of better quality. The frame that has a smooth and shiny coating is better in quality. If the solder joint is smooth, small, and uniform, the quality is better. The parts of the sunglasses are assembled closely. The size and shape of the left and right lens must be the same, and the bridge of the nose must be symmetrical.
