Your eyeglasses would be more durable and your eyes would be healthier if we could do the points in ordinary life as follows. Eyeglasses should always be worn.

You need to know wear glasses to correct vision, slow down the development of myopia. If you often wear off frequently, to see things squint when not wear, over time, make ciliaris. Like muscular tension in the over-fatigue, the eyes will be in a state of over-regulation and cause spasm, which leading to deeper degrees.
Certainly, wearing or taking off glasses varies from person to person. If the myopia degree is below 200, you can with the glasses if see from a distance, and without the glasses if see close by. Often rubbing the lens: the lens surface is very easy to be covered with dust, water vapor and oily substances and so on. Then wearing cheap glasses would have felt blurred vision, clarity decreased, it should be promptly wiped with a soft flannel. You’d better wash the lenses with tap water every day to keep clarity at the same time. You shuold pay special attention to the lenses because they are easily scratched and broken. It will greatly affect sight correction even there is a small gap in the e So you should promptly change another one and reassemble new lens in the optical shop if you found the above situation. Always care the glasses frame: The glasses frame consists of nose pad, body, leg and other components. The glasses assembler will conduct comparison according to actual interpupillary distance and frame interpupillary height of different glasses wearers. According to the face shape to adjust the angle of the nose sets and glass feet to make sure the bend degree of the glass of optical center. So the satisfied glasses are made. It can help with the sight correct of myopia patient with wearing high standard The body of the glasses and lesese frame should be wiped with a dry flannel. Timely equip the lost nose screw. Don’t twist the body and legs of the glasses. You should promptly replace anther ones if they are broken. Do not fasten them simply by adhesive taps or other substitution. This will influence to distort the light focus and clarity, also it mars glasses’ comfortable looking. It may probably cause the discoincidence between light focus of glasses and the pupil center of our eyes, that will lead to the triangular prism effect. So that displacement will happen when we are looking at things. Wearing eyeglass frames were only through self-regulation, for example, only wearing glasses on askew can see the true face of the object, this increasing eye-strain. Or wearing glasses a long-term, the vision will decline and serious will happen squint.
Used for a period of time, the glass frame will be deformed, and the lens quality deteriorates too. Good lens are embryo white, good good transmittance, pale membrane and don’t produce material deformation when moving up and down. In normal condition, the high quality glasses will be good in 2 to 3 years, but the low quality ones particularly the low quality resin glasses can not be used over one year. Once finding yellow lenses, coating loss and fluff, a person wearing glasses should go to the hospital to re-optometry and fit new glasses.
