If we can follow principles listed below, our eyes will benefit more with the women's eyeglasses more durable. Glasses should always wear: Some myopic patients worry about wearing glasses will make myopia degrees deepen, so often wear off frequently. In fact, this worry is unnecessary. You should know that the aim for wearing glasses is to correct visual acuity and slow down myopia development. If you often wear and take off the glasses, you will squint at things without the glasses, and day after day, this will cause the ciliary muscle In the condition of overstrain and over fatigue. Your eyes will be in the condition of excessive accommodation and this will lead to cramp. And the degree of eyes will become deeper.

Certainly, the situation varies when it comes to different people. A person with myopia degree lower than 200 do not have to wear glasses then he can see well nearby. Always clean the eyeglasses online: The surface of the lens can be easily covered by dust, vapor, oil and other matters, and you will feel blurred vision and decreased definition, so you should clean the lens with soft lint in time. At the same time every day it is best to wash lenses with tap water in order to maintain a high degree of clarity. Pay particular attention to the lenses are most afraid of scratches, broken, even the edge of a small gap, which will also greatly affect vi Therefore, the above situation if found, you should replace it immediately to the optical shop and reassemble a new lens. Take regular care for the framework: framework consists of nose setoff, body, leg and other parts. The provider should compare the actual pupil of different buyers with the hight of the frame. Depending on the face, adjust the nose care, body, legs tilt angle to determine mirror curvature of the lens optical center in the mirror circle, to adjust out satisfactory glasses for the myopic patients, myopic patients wearing frame spectacles can well For the legs and rings, they should be waped by soft cloth often. Put on the screw on the nose set in time if it is dropped. Don't twist the legs randomly, and change for new ones if it is broken. Do not use adhesive tape or other substitutes to band casually, which will not only affect the optical center offset and clarity, but also impede aesthetic. This is likely to make lens optical center and the human eye pupil center difficult in coincidence and it will produce prism effect, so the object image displacement occurs. People wearing the prescription sunglasses can see the object clearly with self adjust such as wear the glass wrongle, so the tiredness of eyes will be worsen. The sight will be dropped with long time wearing, and the strabismus will be caused in serious condition.

Used for a period of time, the glass frame will be deformed, and the lens quality deteriorates too. Good lens has glass fost, and with good luminousness and light film color, and no image deformation will occur if move the lens from top to down. Generally, high-quality lenses are sustainable for over 2 or 3 years, while the poor one, especially the hard resin can't even live for 1 year.
