Can the degree of eyeglass lenses be adjusted?

Because people nowadays spend a lot of time and energy watching TV, playing computers and mobile phones, many people suffer from myopia. When myopia occurs, it has a great impact on people's daily life and is very inconvenient. People with myopia will wear a pair of glasses, but if they do not protect their eyes after wearing the glasses, the degree of myopia will still increase. Is it possible to adjust the lens power of glasses?

The power of eyeglass lenses is fixed and cannot be directly adjusted up or down. The store must have replaced the lenses for you. Because the store did not prescribe glasses for you according to the correct eye test data and there was a deviation, the store should replace the lenses, even if they lose money. What's more, the profit margin of lenses is very high. If we sell you lenses worth more than 100 yuan, the cost is only about 20 yuan.

Usually you should pay attention to protecting your lenses:

Do not touch the lens with your hands from time to time, as this will leave fingerprints and dirty the lens, and will also scratch the lens if touched for a long time.

If the lens is dirty, do not wipe it with the corner of your clothes or hard paper. You can blow on the lens with your mouth. After the lens is blurred by the water vapor, wipe it with a soft tissue. It is best to use a cloth specially used for cleaning glasses.

When wiping the lens, you should be careful to wipe it in one direction to avoid wiping back and forth which may damage the lens. When sleeping, wrap the lenses with a glasses cloth and put them in the glasses case to avoid dust.

The cloth used to wipe glasses also needs to be cleaned from time to time. You can wash it with soap or laundry detergent, dry it, and put it in the box.

Glasses cannot be treated by just wiping them. You can wash them once a week or half a month, and then clean them with detergent to prevent water vapor from blocking your vision. The cleaning method is: first rinse the dust off the mirror surface with water, then use neutral soap or detergent to clean it, and finally rinse it with clean water and wipe it dry with a glasses cloth!
