Each pair of glasses has its own size.
People began to shop for myopia glasses online, but because of lack of experience, many times the size of glasses is not appropriate. At this time they used to complain about the business or glasses. It is really because that they do not see the size of the frame. Just like our clothes and shoes, each qualified frame has its own size. Usually, the size will be marked on the inside of the temple or the bridge of the nose. The manufacturer will clearly mark the width of the frame, the width of the bridge of the nose, and the arm length of the glasses.
Who should wear low bridge glasses?
According to the website of the American Optical Association, low-bridge glasses are for people with a low bridge of the nose (when your nose is at or below the pupil level), a wide face, or high cheekbones. This pair of glasses fit anyone with a low nose. If you have a tall bridge, it's great to have a bridge near the eyebrow line. If you have a low bridge of the nose, a more curved brow or a lower bridge of the nose frame is a better choice. Because the dimensions of the bridge are measured from the inside of the frame, a thick-sided frame with the same bridge dimensions and a very thin frame will not fit. It may actually be too small. Because it allows for extra edges.
If you need reading glasses when using a computer, you may want to choose a lower reading glasses power. This is because most people view their screen from a greater distance from their eyes than when they are reading a book or a magazine.
However, if you need reading glasses for looking at something very close or very small, you may need a pair of stronger power glasses.
In most cases, when two reading glasses’ powers seem equally suitable, choose the glasses with the lower power. Picking reading glasses that are too string typically will cause more discomfort problems than reading glasses that are a little too weak.
What is an MR lens?
MR is the brand name of optical lens raw materials produced by Mitsui Chemicals in Japan. MR series is available in three different refractive indices (1.60, 1.67, 1.74): MR-7, MR-8, MR-10, and MR-174. MR-7 and MR-10 have higher thermal deformation temperature and excellent dyeing, which are widely used in the field of sunglasses. MR-8 has the most balanced performance index and is suitable for the production of lenses of any strength. It has the highest market share in lens materials with a refractive index of 1.60. MR-174 is a high refractive index lens material, which is mainly used in the production of ultra-thin lenses.
1970 Oversized Square Eyeglasses
Now a lot of designers are giving us cool square lenses because they want to bring back the fashion of the 1970s and 1980s. Each one is timeless and must be tried.
Type of eyeglasses cloth
There are many kinds of cloth for glasses. There is mainly sheepskin eyewear cloth, and there is microfiber eyewear cloth. There are suede and double-sided cloth and so on. Professional eyewear cloth must use more than 200 grams of weight/per cubic centimeter of microfiber. This kind of raw material chemical fiber is fine, and tactility is soft, so it will not damage the lens. This kind of wipe cloth can be used on a computer screen. The two sides of the cloth are different, and the smooth side is used to scrub the lenses. Because the dirt on the lens is mostly small. The rough side is designed to give you more friction when you touch it with your finger, so you can use it more easily, and you can clean it more.
How to use the eyeglasses holder straps?
Slide the plastic holder at each end of the string to the ends of the eyeglass arm. Some glasses retainers have pockets at the end of the line instead of plastic retainers.The pockets cling to the arms of the glasses. Tie the string around your head and put your glasses on. Have the rope tied around your neck and your glasses in front of you. If you want to take your glasses off for a while, hold them over your chest and release them so they can hang on the cord.
