The benefits of bifocal glasses

People with myopia often need to wear bifocal glasses after the appearance of presbyopia. The upper and lower parts of the lens have different diopters. The upper part is used to see distant objects, and the lower part is used to read and do close work. In addition to presbyopia, some people who work long hours in close quarters need bifocals to reduce eye strain. Studies have shown that long-term nearsightedness is the main cause of myopia. According to the adjustment principle of the eyeball and the height of the patient diopter, a reasonable measure is to wear myopia glasses with full correction when seeing the blackboard in class. When reading and writing. they should take off glasses or wear low myopia glasses. But the practice of continuously removing and putting on or changing glasses is clearly unrealistic. Bifocal glasses will solve this problem.

If you have a wider face, it is better to choose larger glasses, which can better modify the face and make the face smaller.


How Do Adjustable Glasses Work?

Adjustable glasses are featured with the fluid-filled lens technology that lets you adjust the power of the lens based on the correction level you need. You can twist the dial until you can see clearly. So, adjustable glasses are also called dial vision glasses.

Each of the lenses on adjustable glasses has a membrane that moves outward or inward based on how much fluid the lens contains. The liquid comes from a small syringe connected to each arm of the glasses. You move the dial to pump fluid in or out of the lens. As fluid enters the lens, the lens’s power increases. This can correct farsightedness. Pumping the fluid out can correct nearsightedness.

The principle of adjustable glasses is the same as vision ability. You change the physical shape of the lens just as the physical shape of the eyeball so as to correct your vision.



How to clean the lenses?

When wiping lenses (especially the rimless glasses of resin lens), you must use a special wipe lens or soft handkerchief or paper. When you wipe the lens, you can only wipe it in one direction, not in circles, and don't touch the lens with your fingers. When the lens is stained with dust and sand, it should be washed with water before wiping, otherwise, the lens is likely to be abraded, and the operation should be gentle. At ordinary times, when cleaning, do not exert too much force, pay attention to the grasp of strength. When wiping the lens, it is best to take the side frame with one hand, and the other hand takes the glasses cloth to wipe gently. In order to prevent the lens film layer falls off, do not use alkaline detergent to wipe the lens. Therefore, when bathing or playing at the seaside, glasses should be properly kept to avoid water vapor or seawater caused by corrosion of glasses.
