Daily Maintenance and Care of Glasses
1. Take off your glasses with both hands
-
Take off the glasses with both hands to prevent the glasses from deforming due to uneven force when you take off the glasses with one hand.
-
Secondly, the glasses should not be too tight or too loose. The distance between the two temples of the glasses and the curvature of the temples should be appropriate. For example, the temples of the glasses should bent just on the ears and should not too tight.
-
Also pay attention to the appropriate lens eye distance (the distance between the cornea and the lens), not too close or too far. Generally, the eyelashes cannot be swept away from the lens, and try to be as close to the eye as possible.
2.When not in use, it should placed in the box
-
Many people take off their glasses and place them at will. As a result, the glasses are often damaged. They should be put in the glasses case as much as possible to avoid squeezing. When placing the lens, the surface of the lens faces up to avoid wear.
-
Glasses should not placed in hot and humid environments for a long time, such as saunas, under the windshield of cars, bathrooms, and kitchens, so as not to accelerate lens aging and frame deformation.
3. Clean the dust before wiping
-
The surface of the lens is easily covered by dust, moisture, grease, etc. At this time, after wearing the glasses, the vision will be blurred and the clarity will be significantly reduced. It should be cleaned in time to maintain the high clarity of the lens.
-
When cleaning the mirror surface, you should first rinse (flick) the dust from the lens, and then use a neutral detergent such as detergent.
-
If people with higher cleaning requirements can choose professional lens cleaner, lens cleaning paper or spray to clean, the cleaning effect is better and it can be sterilized.
-
It should be reminded that when wiping the glasses, it is best to use a special glasses cloth to avoid wearing the lenses.
4. Pay attention to frames and lenses
Pay attention to the loose and deformed frames
-
The lens body and lens feet should not be twisted at will. If they are broken, they should be replaced in time. If the nose pad is loose and the lens frame is deformed, it should be treated and repaired in time to avoid affecting the deviation of the optical center of the glasses and the axis of astigmatism, causing visual fatigue.
-
If the width and narrowness of the temples are inconsistent, and the height is unbalanced, it may cause the lens parameters to change and cause discomfort in wearing.
Do not use polished lenses
-
If the lens surface has a large degree of wear, it will cause a decrease in light transmittance and blurred vision, which will not only cause symptoms such as visual fatigue, dry eyes, and astringent eyes, but also may cause rapid deepening of myopia.
