【Sun Glasses Introduction】
Sunglasses are a type of vision health care product designed to prevent the intense sunlight from damaging the eyes. As people's material and cultural standards improve, sunglasses have also become special accessories for beauty or personal style expression.

Common sense
Wearing sunglasses improperly can lead to eye diseases. There is no need to wear sunglasses in conditions such as overcast days or indoors where the light is dim. Some people wear sunglasses regardless of the strength of the sunlight, even in twilight, dusk, or while watching movies or TV. This will inevitably increase the burden on the eye's adjustment, causing eye muscle tension and fatigue, leading to decreased vision and blurred vision. In severe cases, symptoms such as dizziness and dizziness may occur. For infants and children whose visual system development is not yet complete, it is not suitable to wear sunglasses. In addition to the sunglasses with glass lenses, the other sunglasses have low wear resistance. The user should pay attention to the surface condition of the sunglasses frequently. When the wear affects the clarity, it should be replaced in time.
Sunglass Maintenance
Brilliant sunglasses make you active in the sun, so free. In fact, sunglasses can block the sun, but they can't block the damage from pollution, so you need to take care carefully to avoid embarrassment. The method of maintaining sunglasses is like maintaining ordinary glasses, including cleaning, folding, and storing. However, sunglasses are often taken off and put on, and it is easy to scratch the surface if you are not careful. Therefore, there are some small details that need to remind you: when there are stains on the sunglasses, don't scratch them with your nails, which will easily damage the surface. When you don't wear sunglasses, many people will casually hang them on their heads, necks, or pockets. At this time, the body's movement should not be too large to avoid breaking or damaging them. Some people will put them in their handbags, but I suggest you first put them in a hard eyeglass box and then put them in your handbag to avoid being worn by small things like keys, combs, coins, or contaminated by cosmetics such as lipstick. For drivers who wear sunglasses, they often put them on the dashboard or seat when they are not worn. This is a very bad habit. The hot weather will bake the sunglasses into a shape, especially for plastic frames, so it is best to take them out of the car or store them in the eyeglass box. No matter where you store your sunglasses, remember to keep the lens facing up.

【Eyeglasses Protection】
1. Wearing or taking off glasses with one hand can destroy the balance of the left and right sides of the frame, leading to deformation. It is recommended that both hands hold the legs of the glasses and take them off or put them on along the parallel direction of the cheeks.

2. When taking off and putting on the glasses, it is generally recommended to fold the left leg first to avoid causing frame deformation.
3. It is recommended to rinse your glasses with clear water and absorb the water with a tissue, and then use a special glasses cloth to wipe. When wiping the side of the frame, hold the side of the frame gently and wipe the lenses gently to avoid excessive force causing damage to the frame or lenses.

4、When not wearing your glasses, please wrap them in the lens cloth and place them in the case. If you need to temporarily store them, please place the convex side of the glasses up, or the lenses may be easily scratched. At the same time, avoid contact with corrosive items such as insect repellent, toilet cleaner, cosmetics, hair spray, and drugs, and avoid long-term direct sunlight and high temperature (over 60℃) storage, or the lenses and frames may deteriorate, deteriorate, or change color.


6. Please do not use glasses during intense sports to avoid strong impacts that could cause the lenses to break, resulting in eye and facial injuries. Do not use lenses with wear and tear to prevent color distortion of light from causing vision decline. Do not look directly at the sun or intense light to avoid eye harm.
7. Sun Glasses Maintenance Wearing dazzling sun glasses allows you to enjoy the sun's warmth and freedom. However, sun glasses can block out the sun's rays but not pollution damage, so it's important to take good care of them to prevent any damage. In fact, the maintenance of sun glasses is similar to that of regular glasses. It's important to develop habits for cleaning, folding, and storing them. However, sun glasses are often removed and put on, and it's easy to scratch them if you're not careful. Therefore, there are some details that need to be emphasized: when there are stains on sun glasses, don't try to scratch them with your fingernails, as this can easily damage the surface. When you don't wear sun glasses, many people tend to hang them on their heads, collars, or pockets. At this time, be careful not to move too much, or you might break or tear them. Some people also put them in their handbags. It's recommended that you first put them in a hard eyeglass case before putting them in your handbag to prevent them from being scratched by small items such as keys, combs, or coins, or contaminated by cosmetics such as lipstick.
