Functional zoning of the store

After determining its own positioning, the layout and functional partition of the optical store is very important. From the overall decoration to the details of the layout, they should reflect the professionalism and coordination of the optical shop. The general partitions of the optical shops include the eyeglasses business area, optometry room, contact lens wearing area, processing room, and cashier desk. The eyeglasses business area can be divided into more small modules separately. The division of the area should have a fixed standard. For example, the arrangement of this area can be selected according to the purpose, user group, occasion, and theme of the glasses.



Lens anti-fogging agent

To be specific, a layer of the anti-fogging agent is sprayed (coated) on the surface of the lens to form a dense, absorbent, ultra-thin, and ultra-transparent biological coating. The coating chelates the droplets inside the coating (chelating means processing the material into a digestible form) to form a continuous and supper transparent chelating coating, which converts the droplets into a transparent micro-glass layer, thus preventing fogging. Spray anti-fogging agent on the surface of the lens, and then wipe evenly with an ordinary lens cloth. It can be used on most lenses. They are easy to use but have relatively short anti-fogging time. During use, the lens should not be wiped or washed. Long time use will affect the lens life.


The life of the color-changing lens

There is a reaction fatigue problem in both compound reaction and bond-breaking ring-opening reactions. Therefore, there is a shackle in the process of discoloration, which is the life of the discoloration lens. Generally speaking, high-quality color-changing lenses can maintain more than 90% color-changing effect after 2 years of use.

What are night driving glasses?

Night driving glasses have non-prescription yellow lenses, and the color ranges from pale yellow to amber. Night driving glasses have been manufactured for decades. These yellow glasses were originally sold to hunters as shooting glasses. They continue to be popular with hunters because they enhance the contrast between the birds and the sky is cloudy or cloudy conditions.

Some night driving glasses also have anti-reflective coatings. Night driving glasses reduce glare by scattering and filtering blue light. Blue light is the shortest wavelength and highest-energy part of the spectrum. Unlike light with longer wavelengths, blue light is more likely to cause glare when it enters the eyes.
