Considerate service
They attract a lot of customers through promotions and regular sales, but if they will come back after a purchase is reflected in the service. Now, in terms of service, many optical shops are still relatively homogeneous, which requires entrepreneurs to pay more attention to service details like the accuracy of optometry, the comfort of wearing.
Design principle of progressive multifocal lens
For the same piece of the lens, the top is used to see far, the bottom is used to see close. The upper and lower degrees are different.
There is not a sudden change in the distance degree fixed above the lens to the near degree fixed below the lens, but a gradual transition between the two through gradual changes in refractive power, which has special benefits over common bifocals or trifocal lenses.
What are driving glasses?
Driving glasses refers to the glasses that are specially used for driving, with functions of anti-glare, anti-strong light, anti-rain and fog, anti-fatigue, and other functions. They are suitable for drivers in the day and night to wear glasses for vision protection, better-ensuring traffic safety. They are recognized as the driver's glasses, driver glasses.
Accurate optometry is key.
Optometry before wearing glasses is very key. Children's optometry should choose mydriasis optometry. Mydriasis optometry is a method of optometry designed specifically for children. It works by using drugs to completely paralyze the ciliary muscle of the eye so that it loses its regulatory role. So you can check out the child is true myopia or pseudomyopia. During optometry, you should pay attention to let the child as far as possible to relax, so as not to affect the effect of optometry. For the sake of children's health, it is recommended that parents and friends can take their children to a professional optometry place to choose glasses. In addition, do not rely solely on optometry to determine the child's glasses, but to see which degrees are more suitable.
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.
Which Reading Glasses Are Most Suitable for Me?
If you have never previously required prescription glasses to improve your vision such as nearsightedness or farsightedness or astigmatism, it is highly like that you can correct your vision with non-prescription reading glasses.
People around the age of 40 to will benefit from the low power reading glasses because of the progressive nature of presbyopia. In other words, you do not need prescription glasses to correct your vision.
However, if you are around the age of 60 or older, the strength of the reading glasses will increase. However, you do not need prescription glasses.
