Do spectacles need maintenance? This is a common question opticians hear from nearsighted people. The answer is that maintenance is required. If the frame glasses are not maintained, they will increase the degree of wear and tear and pose a threat to the protection of vision. Regarding the maintenance of frame glasses, let Vooglam briefly introduce them to you.
There are many ways to maintain your glasses, the main ones are the following:
① Keep the glasses not deformed, so that the optical center of the lens is consistent with the interpupillary distance. Taking off and wearing glasses with one hand for a long time will cause the deformation of the frame due to the uneven force on both sides, so you should take off and wear glasses with both hands.
② Glasses should not be placed randomly and should be put into the glasses case as much as possible to avoid squeezing. When placing, the lens surface should be facing upwards to avoid abrasion of the lens surface.
③ When wiping the glasses, use a special glasses cloth to avoid entraining fine sand particles to wear the lenses. The cleaning agent should not be corrosive.
The sweat of the human body is also corrosive to a certain extent. If the glasses are stained with sweat, they should be cleaned in time. If the lens is stained with dust or sand, rinse it with water first, then wipe it with a soft lens cloth. Dirt that is really difficult to remove can be wiped off with a neutral detergent. If it is stained with oil and fingerprints, it should be wiped first and then cleaned with lens cleaner. In addition, it is necessary to regularly go to the optical shop for cleaning and adjustment.
④ Glasses should not be placed in a high temperature and humid environment for a long time, such as under the windshield of the car, bathroom, or kitchen, so as not to accelerate the aging of the lens and the deformation of the frame.
