Can you change two pairs of glasses?
There is not much difference between these two glasses, so they can be exchanged.

Glasses are lenses embedded in the frame and worn in front of eyes to improve vision, protect eyes or play a decorative role. Mirrors can correct a variety of vision problems, including myopia, hyperopia, astigmatism, presbyopia or strabismus, amblyopia and so on.

Glasses consist of lenses and frames. There are 15 kinds of myopia glasses, hyperopia glasses, reading glasses, astigmatism glasses, flat glasses, computer goggles, goggles, night vision goggles, goggles for e-sports games, sunglasses, toy glasses and sunglasses. There are also special glasses for viewing 3D stereoscopic images or virtual real images. Other types of glasses include goggles, sunglasses, goggles, etc. , provide all kinds of protection for the eyes. Modern glasses usually have a nose pad in the middle of the lens and a cushion where the left arm and right arm rest on the ear. People who love beauty or are not used to wearing glasses can choose to correct their vision with contact lenses. Although contact lenses and laser correction surgery have become more and more popular in recent years, wearing glasses is still a safe and effective tool to correct vision.

Protection of glasses

1, taking it off with one hand will destroy the left and right balance of the spectacle frame, resulting in deformation. I suggest you hold your temples with your hands and remove them in parallel on both sides of your cheeks.

2. Generally, the left temple is folded first when taking it, which is not easy to cause the deformation of the mirror frame.

3. It is suggested to rinse the glasses with clear water, absorb the water with a paper towel, and then try to wipe them with a special glasses cloth. It is necessary to hold the edge wire of the mirror frame on one side of the wiping mirror and gently wipe the lens to avoid damaging the mirror frame or lens with excessive force.

When you don't wear glasses, please wrap them in glasses cloth and put them in the glasses case. If temporarily placed, please put the convex surface of the glasses upward, otherwise it is easy to wear out the lenses. At the same time, glasses should avoid contact with insect repellent, toilet cleaning supplies, cosmetics, hair gel, medicines and other corrosive substances, and avoid long-term direct sunlight and high temperature (above 60℃), otherwise it will easily lead to deterioration, deterioration and discoloration of lenses and frames.

5. Go to the specialty store regularly for plastic adjustment. The deformation of the mirror frame will burden the nose and ears, and the lens is easy to loosen.

6. Please don't use glasses during strenuous exercise, so as not to break the glasses due to strong impact, causing eye and face damage; Do not use worn lenses to prevent vision loss caused by scattered light; Please don't look directly at the sun or glare, so as not to hurt your eyes.

Cleaning glasses has a doorway.

The principle of cleaning glasses is to keep them clean, free from oil stains and avoid scratching the lenses. It can be cleaned with neutral soap or special detergent, and then wiped with mirror paper or tissue paper after being cleaned with clear water. Many people have the habit of picking up skirts, handkerchiefs, etc. Wipe the lens, which is not correct, because rough materials are easy to scratch the lens. Clean the joints between the frames and gently brush off the dirt with a soft old toothbrush.

Be careful when collecting glasses.

The way glasses are placed should also form a fixed habit. Wrap the lens with flannel first, then fold the left frame and then the right frame. In order to prevent the glasses from being stressed, you can put them in a hard glasses storage box.

Maintenance of contact lenses

Gently thin contact lenses cling to the eyeball, once they are contaminated, they will directly hurt the eyes, so don't be lazy in cleaning and maintenance.
