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 corrosive substances such as insect repellent, toilet cleaning products, cosmetics, hair gel and medicine S, and avoid long-term direct sunlight and high temperature (above 60 degrees Celsius), otherwise it will easily lead to deterioration, deterioration and discoloration of lenses and frames.

5. Go to the 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. ■ There are doorways to clean glasses.

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.

Although glasses are small things, cleaning and maintenance are very important. Unfortunately, many people have only a little knowledge, which will damage their glasses, hinder their viewing and even accelerate the deterioration of their eyesight. We really can't be careless If you want to know more detailed maintenance methods, or have any questions, you are welcome to bring your glasses to Baodao Optical, and you will get a satisfactory and thorough answer.

2. 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.

■ Mud comes out without staining.

In addition to patients with eye diseases, general contact lenses will suffer from three kinds of pollution; One is external pollution, such as dust, grease, cosmetics and detergents in the air. Second, the eyes themselves, such as protein in tears and mucus secretions. The third is the pollution of bacteria and mold. Therefore, the cleaning and maintenance of contact lenses should not only carefully avoid scratches, but also completely accomplish three tasks: cleaning, sterilization and deproteinization.

■ Maintain the system to observe the eyes.

In principle, there is no perfect maintenance system. Some cleaning chemicals are effective, but they can cause allergic irritation to some people's eyes. Therefore, when you buy contact lenses, you must ask about the maintenance system that is most suitable for your living habits and physiological conditions, and don't mix different maintenance systems at will. Generally speaking, you should pay attention to the following points when choosing a maintenance system:

1. Approved by the health department.

2. No allergic or irritating reaction to eye safety.

3. Good cleaning effect.

4. It can be completely sterilized.

5. The deproteinization effect is good.

6. conform to your living habits.

7. Simple and easy to use.

8. The price is reasonable.

■ Cleaning begins with both hands.

Although many maintenance systems are called "hands-free", experts suggest choosing a self-cleaning maintenance system as far as possible. The cleaning effect can be determined by finger touch and eye observation, which is both reassuring and practical. Before you start cleaning your contact lenses, wash your hands, especially the dirt under your nails.

■ Four days of cleaning

(1). Remove stains with cleaning solution; After dripping the cleaning solution according to the instructions, gently rub the lens with your fingertips for about 30 seconds.

Will leave stains and deposits on the lens.

(2). Wash the cleaning solution; Rinse the cleaning solution and stains thoroughly, and use special maintenance solution or physiological saline for contact lenses.

(3) disinfection and protection of lenses; Use the disinfectant and method specified in the maintenance system.

(4) Keep it in a special box; Don't neglect to clean and disinfect the collection box regularly, otherwise the hard cleaning work will be polluted again.

■ Deproteinization every week

Protein contained in tears is easily attached to the lens, and it is stubbornly deposited on the lens. Even if it is cleaned every day, it cannot be completely removed, and the longer it accumulates, the more difficult it is to remove, which will make the eyes red, photophobia and lens discoloration, stimulate the immune system of the eyes to produce antibodies, and cause diseases such as "papilloconjunctivitis". Enzymes in deproteinized cleaning tablets can decompose protein structure, chop and eliminate adhesion, thus achieving cleaning effect. Usually deproteinization can be done once a week.

3. Maintenance of sunglasses

Dazzling sunglasses make you active in the sun, so free. In fact, sunglasses can block the sun, but they can't stop the pollution damage, so take good care of them so as not to lose face.

In fact, the method of maintaining sunglasses is the same as maintaining ordinary glasses. Cleaning, folding and storage should become a habit. It's just that sunglasses are often taken off and worn, and they will scratch if you are not careful, so there are some small details to remind you: when sunglasses are stained, don't dig with your nails, it's easy to scratch the surface.

When sunglasses are not worn, many people hang them on their heads, collars or pockets. At this time, the range of body movements should not be too large to avoid being broken or damaged. Or someone will put it in a handbag. I suggest you put it in a hard glasses case first, and then put it in a handbag to avoid being worn by small things such as keys, combs and copper plates, or being contaminated with cosmetics such as lipstick.

The sunglasses worn by drivers are often put on the dashboard or seat without wearing, which is a very bad habit. Sunglasses will be baked and deformed in hot weather, especially plastic frames. It's best to take them out of the car or put them in the glasses storage box.

No matter where you put your sunglasses, make sure the mirror is facing up.
