Repair your old eyeglasses.
Whether it's a scratch in the lens, a dent in the frame, or a missing screw, it's possible to get your glasses fixed and save you a lot of money. In America, a small screwdriver in an optical store, an electronics store, or even a Christmas cracker is enough to help. Or you can run some thin wire through the hole where the screw is, then use some pliers to wind the wire around the inside of the frame a few times, and then use the pliers to screw the ends together. You can use commercially available scratch repair kits to fix scratches on your lenses, or you can use household products like toothpaste or baking soda to polish and remove scratches. If you don't have time to do it yourself, you can call a professional to fix it.
How To Choose Better Night Driving Glasses?
Choose and buy glasses to use a special night with anti - strong night driving lens. The demand is to block 80-90% of the strong lights and harmful lights, and at the same time to make the road more clearly. Choose glasses with thicker lenses, they are more durable and protect the eyes of drivers against irritation and accidental breakage. As common sunglasses and color-changing glasses are only suitable for daytime wear, wearing them at night will seriously affect the driver's vision.
Common light yellow night driving glasses can only block a small amount of light, and is not very suitable for night driving glasses standards. Therefore, in the choice of lenses of night driving glasses, we must do the selection and demonstration of the national authority of the formal institutions to test products, to achieve the desired effect in actual use. Don't buy products that are not up to standards from vendors. Such products not only do not block the lights but may affect the driver to see the road ahead, affecting the safety of the train operation.
Wearing glasses correctly will not get deeper degrees
The development of myopia is not directly related to wearing glasses. Patients with myopia wear suitable glasses and pay attention to eye hygiene, and the degree of myopia will stabilize at a certain level. But if you think that with glasses, everything will be fine. If you don't pay attention to eye hygiene in normal times, if you continue to keep your eyes in a state of fatigue for a long time, it will lead to vision loss and deepening of myopia. In addition, wearing improper glasses such as no optometry or inaccurate optometry, too large power, will increase the burden on the eyes, reduce vision and deepen the power. For some people with high myopia (more than 600 degrees), although they insist on wearing glasses, the degree will still deepen, accompanied by changes in the fundus, which is medically called pathological myopia. This deepening of myopia is related to the degree of myopia and family and has nothing to do with wearing glasses.
Tungsten carbon glasses frame
Tungsten carbon material, one of the obvious advantages of this material is that it has good toughness and is ultra-lightweight. People will feel no pressure when wearing such glasses. It is good if you are a sportsperson who chooses it.
Progressive multifocal glasses are more powerful.
On the premise of the dual vision correction effect, the progressive lens has more stable and complete functions. They provide lasting clear vision. Because the added value is continuously and slowly increased in the related area, the wearer can get a lasting clear vision from the far place to the near place through the progressive glasses. The appearance is better than that of bifocal and trifocal lenses, and there is no subplate dividing line.
Anti-reflection Coating
Anti-reflection Coating, known as reflective coating and antireflection film, is called anti-reflection coating in English, or AR Coating for short. Initially, anti-reflection coating technology was used in the sights of weapons. It was only after the war that the technique was used to improve the performance of eyeglasses. Another problem occurs when taking pictures because the lens's surface is relatively reflective. The resulting photos don't show the eyes of friends who wear glasses. This problem is solved by plating anti-reflection film.
Different Type of Lenses: How to Choose
In this section, we will list some of the lenses for glasses.
Plastic lenses: In 1947, the Armorlite Lens Company in California introduced the first lightweight plastic lenses. The lenses were made of a plastic polymer called CR-39, because it was the 39th formulation of a thermal-cured plastic developed by PPG Industries in the early 1940s. Plastic lenses are light and low cost.
Polycarbonate lenses: polycarbonate lenses were first introduced in the 1970s and they have become increasingly popular anad remained for a long time. Polycarbonate glasses are slighter and significantly more impact-resistant than CR-39 plastic, making them a preferred material for children’s eyewear, safety glasses, and sports eyewear.
