What is a qualified plano lens?
First, identify the surface. High-quality products should not have obvious scratches, pitting, edge collapse, sand holes, water ripples, bubbles, and other surface defects. Put glasses next to the place of 33 cm or so at the moment. When looking at the object through glasses, there is no phenomenon that the objects become big or decrescent, and you should not have a feeling that the objects are beating. Otherwise, the quality of the glasses has a problem. Next check through the instrument identification. Finally, check whether the trademark, manufacturer, and quality certificate are true and reliable. The lens of the international famous brand product is often engraved with the manufacturer's trademark, which can be found by careful observation on the edge of the lens.
How to protect your contact lenses?
When wearing contact lenses, do not drop any eye drops, and only use a special moistening solution for contact lenses. In daily life, we recommend that dry eyes can be relieved with lubricating fluid, but we do not advocate frequent use of lubricating fluid, so as not to make the eyes become dependent on lubricating fluid. The right way is to do blink training. The ingredients contained in the eye drops will remain in the lenses, which will cause certain damage to the eyes and pollute the lenses. Some eye drops can make the lenses tinted after use, which will affect the transmittance and a refractive number of the lenses and make the vision blurred. Ladies who need to make up should wear contact lenses before making up. When removing makeup, remove contact lenses before removing makeup, to avoid the makeup sticking to the lens and damaging the lens and eyes. Lenses should not be lent to others to avoid cross-infection of eye diseases. You can't wear contact lenses while swimming or bathing.

Study On the Night Driving Glasses
Researchers at Harvard's Schepens Eye Research Institute recently conducted a study to find out if wearing night driving glasses while driving at night is good for vision. All 22 participants drove under four conditions that simulated night driving, wearing either yellow night driving glasses or glasses with clear lenses. Each participant drove with or without the headlight glare simulator activated to simulate the effect of oncoming traffic. The study found that wearing glasses while driving at night didn't seem to improve: how well the participants were able to recognize pedestrians at night and negative effects of headlight glare on pedestrian detection. Our data suggest that wearing yellow lenses while driving at night does not improve performance at the most critical task: pedestrian detection, the study's authors said. A small 2019 study showed that night driving glasses can actually slow down visual reflection by a fraction of a second, making night vision worse.
Disadvantages of glasses
They can distort vision, especially at the edges of lenses if you have strong prescriptions or astigmatism. Some people have trouble adjusting to progressive lenses. These lenses fog up and splash in the rain. Due to the limitation of the frame itself and the effect of the prism effect in the peripheral part of the glasses, the wearer can see a relatively narrow field of vision.
How to clean the lenses?
When wiping lenses (especially the rimless glasses of resin lens), you must use a special wipe lens or soft handkerchief or paper. When you wipe the lens, you can only wipe it in one direction, not in circles, and don't touch the lens with your fingers. When the lens is stained with dust and sand, it should be washed with water before wiping, otherwise, the lens is likely to be abraded, and the operation should be gentle. At ordinary times, when cleaning, do not exert too much force, pay attention to the grasp of strength. When wiping the lens, it is best to take the side frame with one hand, and the other hand takes the glasses cloth to wipe gently. In order to prevent the lens film layer falls off, do not use alkaline detergent to wipe the lens. Therefore, when bathing or playing at the seaside, glasses should be properly kept to avoid water vapor or seawater caused by corrosion of glasses.
