What is an aspheric lens?
Strictly speaking, any lens with a refractive surface that is not a sphere is an aspheric lens, including ordinary astigmatism lens, progressive multi-focal lens, Aspheric apical lens, etc. But customarily, our daily aspheric lens refers to the Aspheric apical lens. From the center of the lens to the periphery, the radius of curvature increases (the surface of the lens flattens out).
Difference Between Driving Glasses And Night Vision Goggles
The use of driving glasses and night vision glasses is different. When sunlight is projected on the road or water, it directly stimulates the eyes, making them feel dizzy, tired, and unable to see for a long time. Especially when you are driving a car, doing outdoor entertainment activities, it will not only affect our work and entertainment mood, and even affect our judgment of the image and cause danger. The polarized driving glasses can be used during driving, fishing, skiing, rain, etc. when there is a strong reflection of strong light. Night vision goggles are usually used at night and have great applications in transportation, the military, and other fields. A large amount of night vision equipment has been used as a winning strategy to dominate night combat. Combining night vision technology with weapons and equipment will greatly improve the effectiveness of weapons and equipment in getting information, conducting strikes, commanding troops, and coordinating operations at night and in bad weather.

About Polarized Sunglasses
Polarized sunglasses only absorb the reflected light of the object itself, presenting what is being seen, making the field of view clearer and thus reducing eye strain. In addition, the light through a bumpy road, water, and other places also can produce irregular diffuse light. The polarized lens can be this kind of optical filter, only absorbing the reflection of the object itself. Because of its high-efficiency filter layer, the UV blocking rate of the polarized sunglasses is 99%, which can effectively reduce UV damage to the eyes. And if you are driving, fishing, traveling, skiing, it is recommended to choose more powerful polarized sunglasses.
The Cons of Titanium Glasses
However, there are some negative voices of titanium glasses. Titanium glasses are more expensive than other materials. So, when purchasing titanium glasses, beware of the differences between pure titanium and titanium alloy.
Your glasses are not symmetrical.
If one side of the frame looks higher than the other, you need to adjust the arm. If the right side is higher than the left, gently bend the left arm at the hinge or where the arm bends behind the ear. If the left side is higher than the right, gently bend the right arm at the hinge or where the arm bends behind the ear. Adjusting the frames a little at a time may damage your glasses. Place your arms in warm water to make them easier to adjust. Use only warm water from the tap. Don't use boiled water! Because it affects the coating on the lens. If one adjustment is not in place, it can be adjusted several times, and the above methods can be comprehensively used. If the adjustment is really bad, then you have to go to the optical shop to ask the staff to adjust.
