What should I do if my glasses fog up?

In life, we can see people wearing myopic glasses everywhere. In winter, the problem of fogging eyes is very serious. For example, when you just go from outdoors to indoors, a layer of fog will appear on your eyes due to the rapid change in temperature. At this time, you may not be able to see anything clearly. This will not only bring inconvenience to your life, but may even cause some dangers. So how to solve the problem of fogging glasses?

What should I do if my glasses fog up?

1. Buy a bottle of anti-fog agent for glasses

Generally, the price ranges from 5 to 10 yuan per bottle. Spray it on the lens and wipe it. It can not only clean, remove dirt and prevent frost, but also has a very obvious anti-fog effect. It can usually ensure that there is no fogging for one or two days.

But remember, don't buy fakes just for the sake of cheapness. After all, they are chemical preparations and are so close to the eyes. If you use fakes, the chemicals attached to the surface of the lenses will evaporate due to heat and cause great damage to the eyes.

Generally, some eyewear stores may have promotions where customers who get glasses can get a bottle for free, so you can ask when you get glasses.

2. Buy an anti-fog glasses cloth

Well, the price is a little expensive, around thirty or forty, but there are also some for fifty or sixty. This is a specially treated glasses cloth. It may feel a little damp on the surface, but it is very effective. It not only prevents the lenses from fogging, but also protects the lens film layer very well.

At present, most of the anti-fog glasses cloths in China are exported, so most of them comply with safety regulations. It is available in most regular eyewear retailers.

3. Clean the lens with soap or detergent

Remember not to use soapy water directly, as that will damage the lens film.

The correct way is to wipe the lenses with semi-dry, slightly soft soap, and then polish them evenly with a glasses cloth. No water is needed.

You can also put a little detergent on the lens cloth to wipe the lenses. Remember, it’s just a little bit! This will prevent the lenses from fogging up. Similarly, you can also use this method to wipe your car windshield, so you don’t have to worry about the glass fogging up! New skills, get them now!

4. Equip a pair of anti-fog lenses

Currently, there are mainly two types of anti-fog lenses. One is the domestically produced Dianjin permanent spray-free anti-fog lens (strictly speaking, it also belongs to an American company). It has a high cost performance, good effect, and the price is acceptable to most consumers. The other one on sale is the imported Essilor anti-fog lens, which also has a good effect.

But the price is a bit high, because that brand's products are generally expensive, and it costs over a thousand dollars in an eyewear store. The average working class may not be able to afford it, except for the rich!

5. Homemade anti-fog agent for lenses

Haha, this is the most effective, economical, safest and lowest-cost method I discovered myself based on the principle of anti-fog spray.

First, you need to prepare 30ml of glycerin and 10ml of soap solution. Mix the two and shake well. Then add a few drops of turpentine and shake well.

When using, just apply a little bit of the homemade Essilor anti-fog agent on the lens, and then wipe it gently with a glasses cloth. The anti-fog effect can last for 3-4 hours. Even the problem of glasses fogging up when wearing a mask can be solved!

The principle of lens anti-fog agent is: soap contains oil components, and when soapy water is applied to the lens, the lens will not easily be stained by water vapor. However, applying soap directly to glasses will not prevent fogging for as long and the effect will not be as good, so glycerin is added to slow down its evaporation.
