Usually in our daily lives if we can do the following number of points, then our eyeglasses will be more durable and more beneficial to your eyes. Always wear the glasses: Some myopes are worried that wearing glasses will deepen the myopic degree, so they often wear and take off the glasses. Actually, this worry is needless. 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.
Of course, whether wear it or take off it depends on individuals. You can wear it to see long distance and take off it when you see something near if your myopia less than 200 degrees. Always clean the cheap glasses: 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. Besides, you had better to wash the lens with water every day to maintain the high definition of the lens. You should specially note that lens should not be scratched and broken. Even a small nick at the side will greatly influence the vision correcting e Therefore, if you find the abovementioned situation, you should go to the glasses store to replace and reassemble new lens. Framework of the regular care: Framework is composed of the nose pads, body, legs and other parts. Assembler depends on the practical pupil distance of the persons who get the right lenses for their eyeglasses and frame height compared. According to different face shapes, opticians adjust the tilt angle of nose care, body and legs; determine the lens optical center's mirror curvature in the mirror circles and adjust out the glasses satisfied by myopia, and they wearing frame glasses well 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. Don't use adhesive tape or other alternatives to bunch them. This will not only influence the difference of the center of optics and the clearity, but also influence the appearence of the glasses. This will possibly make the light center of lenses and the center of people's eye pupil hard to overlap and lead to the effect of triple prism which will make the things people see move. The people who wear eyeglass frames can only adjust the glasses such as wearing it in an ablique way. Hence increasing eye-strain such as the sight will be declined or even squint if you wear it for a long time.
Both the frame will be deformed and the lens quality will be changed if the glasses were used for a period of time. Good lens with a base embryo white, good transmittance, membrane pale, moved up and down depending on the lens does not produce material deformation characteristics. 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. Once you find the glasses are changing yellow, the dropping or fluffing of the mask, you should do optometry and have a pair of new glasses in the hospital.
