Types of Optical Frame Glasses

The full-frame glasses have good strength, suitable for athletes and children to wear because the lens is completely protected by the lens ring. They are suitable for a variety of refractive parameters of the lens. The upper part of the lens ring is made of metal or plastic materials. The lower half of the lens ring is made of a very fine nylon wire like the lower part of the lens ring. Rimless glasses are lighter than full-frame glasses. Rimless glasses can be divided into parts type and integral type. The part type consists of a nose bridge (together with the nose pad) and two temples. The combination glasses are divided into two parts. Usually, the front group is equipped with colored lenses, and the rear group is equipped with lenses for correcting refractive errors. The folding glasses can usually be folded at the bridge of the nose and the temple to reduce the space when stored or carried and are mostly used for making reading glasses.


Why does an optical shop carry out the preferential activity?

These activities can attract a steady flow of traffic, but to keep the original flow out. It helps improve the store in the community awareness, expand visibility. It can attract new customers to the store, encourage old customers to introduce new customers, and stimulate old customers to buy again. And then increase store sales and add new customers.



Optical Stores Provide Free After-sales Services

They help check eyesight regularly and check eyesight every six months. They help replace accessories, including all kinds of screws, nose pads, temple tips, protective film, etc. The glasses frame can be repaired and made adjustment, with lens ultrasonic cleaning. They help popularization of science, such as consultation on optical problems in ophthalmology, distribution of eye care manuals, and eye charts. Glasses can be repaired (replaced) free of charge after accidental damage. For consumers, it is undoubtedly a good thing, especially for student consumer groups. Because the students are active, frequently use glasses, and easily have other wear and tear problems.


RIVBOS Polarized Sports Sunglasses for Driving

TAC Polarizing Lenses - RIVBOS lenses are made from cellulose triacetate (TAC) material. TAC has quality optical properties that prevent the shrinkage of PVA polarized light film and has high strength surface scratch resistance. They help restore the original color, eliminate reflected and scattered light, and provide perfect eye protection. Rivbos frames are made from durable TR90 material. These polarized sunglasses feature flexible, stress-resistant frames that are able to withstand pressure without breaking. Whether it's sports or casual, you can show off your unique style.



The refractive index of lens

Refraction law is discovered by Dutch mathematician Snell.It is the law that determines the direction of refracted light in the phenomenon of light refraction. When the light from the first medium (refractive index N1) into the second medium (refractive index N2), part of the light from the first medium into the second medium at the smooth interface will be refracted. The index of refraction is the ratio of the speed at which light travels in a vacuum to the speed at which light travels in the medium. For glasses lenses, the higher the refractive index, the thinner the lens, that is, the lens with the same center thickness and the same degree, the lens with the higher refractive index has thinner edges than the lens with the lower refractive index of the same material.


Who are TR90 glasses for?

Both plate glasses and TR90 frames have their own characteristics and benefits. The plate glasses deduce fashion and are easier to match clothes. It integrates the plate and the texture of the metal, which can better reflect the personality and style. TR90 frames have been widely used in many optical fields like sunglasses, 3D glasses, polarized glasses, radiation-resistant glasses, etc.TR90 frame is so popular in men and women because of its variability. TR90 frame can be perfectly combined with other metals. The neat lines and bright colors bring fresh and energetic outdoor energy to the dull city. The light texture, about half lighter than the plate frame, can reduce the burden on the bridge of the nose, ears, and facial skin, which is very suitable for teenagers who just wear glasses.
