How polarized glasses can help you drive
The most important thing about polarized sunglasses is that they can be a good helper when you drive. When sunlight hits your eyes at an awkward angle, these sunglasses will save your life and save you from potential accidents. Polarized glasses can filter out the sunlight reflected from objects such as roads, snow, water, and other objects. It helps to neutralize the effects of reflected sunlight. Polarized sunglasses bring you an incredibly safe driving experience, with almost no interference and no harm to your eyes.
At night, glare and embarrassing lights are everywhere on the road, especially because random drivers come from the opposite side. Some of these driving high beams may disrupt your vision and cause potential accidents. Polarized sunglasses help reduce glare and save your life. Polarized lenses hardly reflect.
What difference do mono-focal glasses and multi-focal glasses have?
A mono-focal lens is a lens with one focal point. Usually, the myopic far-sighted presbyopia that we see belongs to mono-focal glasses. There is only one diopter on one lens, and this is the single focal point. Multi-focal glasses are lenses that have multiple focal points, that is, multiple diopters. Both mono-focal glasses and multi-focal glasses are visual correction tools, but mono-focal glasses can meet basic vision needs, like fatigue relief, control of depth of diopters, and focus on different distances such as the need to see far and near.But because there are many different diopters on a multi-focal glasses lens, so the elderly can not only see far after wearing. When they see close distance, they do not need to take off glasses or wear reading glasses. Wearing multi-focal glasses is not easy to fatigue.
What Should You Do If Your Glasses Are Broken?
Adjust the frame by yourself. If your frame is tilted, place your glasses on a flat surface to determine which arm is higher than the other. If the right arm looks raised, you'll need to use pliers to bend the left arm down at the hinge. Or, if the left arm is raised, bend the right arm at the hinge. You can bend your metal-framed arms inward. You can turn the nose pad inward if the glasses slip under your nose. To make the frames more flexible, you can heat them with a hairdryer. If the metal frame has broken into pieces, you may need to take it to a professional. However, if your metal frames just bend, you may be able to repair them by yourself.
Why do glasses with the same prescription feel different?
The clarity of the lens changes. In addition to the case of the frame, the lens will be yellow or slightly scratched during use due to long-term absorption of ultraviolet rays, oily contact, dry rubbing by the user, etc., and the clarity of the lens will be affected. However, the clarity of newly equipped glasses tends to be higher, and the comparison between the two will cause discomfort. It is recommended that the new glasses can be used early the next morning. After a night's rest, the eyes will be easier to adapt to the new glasses. Under normal circumstances, new glasses generally require an adaptation period of about a week. After a few days of continuous wearing, the uncomfortable symptoms will disappear.

How do anti-blue light glasses protect the eyes?
The anti-blue light glasses available on the market, no matter what type, etc., are mainly the difference in anti-blue light effect, light transmittance, and frame, which will affect the cost of glasses. Obviously, the lens is the most important of these. I think that it is basically enough to choose 30% to 40% anti-blue light glasses. It is good to cut off the harmful blue light. It is not necessary to completely eliminate the blue light so that the chromatic aberration will not be too large, the light transmittance is better, and it also has a certain anti-blue light effect.
Of course, to protect the eyes, it is not enough to rely on anti-blue glasses alone. The effect of anti-blue glasses is mainly to reduce the probability of eye diseases, and can not effectively relieve eye fatigue. Normal people between the ages of 20 and 40 blink about 20 times per minute. When you open your eyes and stare at a computer screen that changes rapidly, the number of blinks will be reduced to 4 or 5 times per minute, resulting in serious insufficient secretion of scum and dry eyes. Therefore, no matter how urgent the work is, you must pay attention to the rest of your eyes, close your eyes regularly, use eye drops when needed, and reduce the brightness of the screen as much as possible when looking at the screen. When the brightness of the screen is significantly higher than the ambient light It is easy to cause eye fatigue. Try to use it as little as possible in the dark. To be honest, it is more important to develop a good eye-using habit.
