How to Take Care of Your Spectacles
When putting on or removing your glasses, hold them by their temples and then put them on or take them off your face with your fingers, applying equal force on each temple. Removing them with one hand could cause distortion of the frame or loosening of the joints.
When you place your glasses on a level surface, place them with the lenses facing upwards. Otherwise, the surface of your lenses may be damaged.
When your lenses have been soiled, wash them with water and wipe dry with tissue paper or preferably with a lens-cleaning cloth.
In case your lenses are excessively soiled, rinse them with diluted detergent and wash off with water. Avoid wiping the dirty lenses with a dry cloth, for it may damage the lenses and frame.
When wiping your lenses, grip the edge of the frame, holding the lens as you wipe gently.Applying excessive pressure could damage your lenses and frame.
When you have to carry your glasses with you, place them in a spectacle case. Clean thelenses before placing them in the case. Avoid keeping them for an extended period in a place liable to be exposed to insecticides, detergents, cosmetics or chemicals, for it may cause damage to your lenses and frame to deteriorate.
Deformed frames could place undue pressure on your nose or ears. It could also cause your lenses to come off the frame. In case you notice any distortion with your glasses, please consult your optician as soon as possible.
Do not leave your glasses in the car exposed to the direct sunlight 
Do not wear your glasses in a sauna or a steam bath.
