Glasses are our “good partners” and need to be cleaned every day. When we go out every day, a lot of dust and dirt will accumulate on the lenses. If they are not cleaned in time, the light transmittance will decrease and the vision will become blurred. Over time, it can easily cause visual fatigue and even vision loss.
Correct maintenance methods can extend the service life of glasses, maintain clear vision and comfortable wearing. However, using improper methods to maintain glasses, such as dry wiping directly with glasses cloth, can easily lead to scratches on the lenses. In order to avoid making these mistakes, the following article shares the correct methods and precautions for cleaning and maintaining glasses.
1. Putting on and taking off glasses
When taking off and putting on glasses, it must be done with both hands. Incorrect taking on and putting on the glasses will cause uneven force on the frame, resulting in deformation of the frame, which will also indirectly affect the comfort of wearing the glasses and the optical parameters of the glasses.
2. Placement of glasses
When taking off glasses, they should be folded and placed with the side with lenses facing up and the temples downward to prevent the lenses from being scratched. When storing glasses, please avoid contact with corrosive items such as cosmetics, hairspray, and medicines. Do not leave glasses under high temperatures for a long time. High temperatures can easily cause lens deformation or film cracks. When glasses are not in use, it is best to wrap them with glasses cloth and put them in a glasses case. Do not place them on sofas, bed edges, etc. where they can be easily crushed.
3. Lens cleaning and cleaning
We open the faucet and rinse the glasses with water at normal temperature to wash away the dust on the surface. Do not use hot water to clean, as hot water will cause the film on the lenses to fall off.
4. Maintenance of mirror frames
Do not let the glasses come into contact with acids, alkalis and corrosive gases. In summer, when the temperature rises, you sweat more. The oil, sweat, and skin care products on your face contact the surface of the frame for a long time, which can easily corrode the plating and paint layers, and even cause metal parts to rust and produce patina. Friends with sensitive skin May cause allergies. Sweat from the human body has a certain corrosive effect, so try not to stain the frames with sweat, beauty products, insect repellents, medicines or paints and other chemical-containing items that will cause the frames to fade or deform. If the glasses are stained by these items, they should be removed immediately. Clean. If the frame is deformed, if you continue to wear it, it will put a burden on your nose or ears, and the lenses will easily fall off.
How to better solve the problem of patina on glasses?
①Ultrasonic machine
You can use an ultrasonic cleaner to remove the patina on the surface at a place where you are prescribed glasses to avoid bacterial infection of the eyes, causing redness, swelling, pain, itching and other symptoms.
②White vinegar
You can apply white vinegar on the patina, evenly on the front and back, and then use a damp paper cloth to wipe the patina repeatedly until it is clean.
③Glasses cleaner
You can use the professional glasses cleaner provided to spray the patina on the frame, and then wipe it clean with a paper towel.
5. Precautions when wearing glasses
① It is not recommended to wear glasses during strenuous exercise
Ordinary glasses are only for daily use. For outdoor sports or strenuous sports, such as running and playing ball, special sports glasses are used.
② Lenses are most afraid of high temperatures and direct sunlight.
It is prohibited to place glasses in front of the car windshield, under spotlights, or wear glasses while taking hot baths, hot springs and other high-temperature activities.
③Try to avoid wearing “deformed” glasses
Any glasses will suffer varying degrees of damage such as breakage or deformation when exposed to external forces. The deformation of the glasses will cause the distance between the lenses and the eyes to shift, making it impossible to reach the normal wearing level.
Common causes of glasses deformation include:
1. Incorrect usage posture, taking off and putting on glasses with one hand
2. External force, such as falling, crushing, etc.
3. Problems with the glasses themselves, such as soft frame material, insufficient hardness, etc.
Wearing deformed glasses for a long time will not only fail to protect your eyesight, but will also accelerate the development of myopia. This is because the lenses we use are not flat, and the refractive power on each diameter line is not exactly the same, especially astigmatism lenses. If the glasses you wear are skewed, it will cause the axis of astigmatism to shift, affecting visual clarity. Long-term wearing will cause visual fatigue and worsen the degree of vision.
