What are the 7 causes of blindness?

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.


The advantages of metal frames

Its advantage is that the lens is fixed firmly, not easy to fall off. But the weight of the glasses increased slightly compared to the other frames. Full-frame glasses give people a sense of calm. The frame can cover the thickness of the lens very well, suitable for people with high degrees.



Orthokeratology lens

Orthokeratology lenses appeared in the United States in the 1960s and became mature in the 1980s. In 1996, Taiwan first imported the product, and it entered mainland China the following year. It is called OK lens for short because of its pronunciation. After OK lens entered China, it was immediately found by businessmen. A lot of institutions and individuals who do not have the relevant qualifications have flooded into the operation of the OK lens. On July 5, 2001, the State Food and Drug Administration formulated the Regulations on the Supervision and Administration of the Operation, Inspection and Matching of Orthokeratology Lens, which regulated the operating institutions and testing and matching institutions of Orthokeratology lenses. But in China, the rule did not change the course of events.


Should I wear driving glasses at night?

In fact, it is not safe to use any colored lenses while driving. You might consider how much color plays in your average driving experience. Red, yellow, green, orange traffic signs, and other vital signs are designed to remind you to pay attention to safety signals and directions while driving. However, if you see everything turn yellow, you may miss a sign and end up making the wrong decision at the traffic light, or worse, an accident.

Another disadvantage is that they do not have a prescription. If you are looking for a pair of standard night driving glasses on the market, you will find that most of them are standard over-the-counter glasses. To have night-driving glasses that can correct vision, you must customize them in an optical shop, and the price is much higher. Under the hype of the night vision feature, you can expect the cost of prescription night driving glasses to be too high.
