How to repair rimless glasses?
First, insert the wire into a small hole in the glasses near the bridge. Pass it in and out near the bridge, then repeat the process on the other side near the temple. Once you have the thread locked, you can place the lens. Insert it into the frame and place the wire in the built-in groove. Tighten the wire so it holds the lens perfectly, then trim it to the left. Reinsert the lens into the rimless glasses. Do not try to force it back in. The best way is to cut the wires completely and replace them with new ones. Use the same process as replacing wires. To prevent glasses from popping out, tighten the wires regularly.
BLUPOND night driving glasses
TAC Semi-polarized Blue light goggles are designed to change your perspective to yellow with computer blue light polarization. Anti-glare high-definition vision blue-blocking glasses protect eyes from blue light and reduce the contrast of bright blue/white glare and flash. The anti-glare night glasses limit distortion. In addition to polarized driving glasses, you can receive a night vision glasses accessory set, with the EVA glasses hard case, screwdriver, sunglasses bag, microfiber cleaning cloth, glasses clip, and night driving glasses gift box.
Which sunglasses are best for driving, polarized sunglasses or non-polarized sunglasses?
Polarized and non-polarized sunglasses are the same in the ability to protect against ultraviolet rays. But when you work as a driver, in addition to the front of the sun, sometimes there are highway road reflective lights, other car body reflective lights, and so on. Glare will make people's eyes uncomfortable and fatigue, and affect the clarity of vision, stimulating the eyes. Polaroid lenses can filter out light from different angles, so when you driving, is best to wear polarized sunglasses.
Evolution of photochromic lenses
Thirty years after Corning invented color-changing glass lenses, another company has carried forward the color-changing glass lenses --Transitions Optical. In 1991, it became the first company to commercially manufacture resin color-changing lenses. Since its inception, the company has been a joint venture between PPG Industries (51%) and Essilor (49%). In April 2014, Essilor acquired a 51% stake in PPG. At present, the mainstream is resin photochromic lenses.
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.
What Are Bifocal Glasses?
Bifocal lenses are divided into two parts to accommodate two different prescriptions in one lens. One area of the lens will have one prescription (usually distance) and a segment in the lower half will have the other (usually near vision).
Bifocal glasses are most used to correct presbyopia - an age-related eye condition where the eyes begin to struggle to focus on anything up close. This difficulty usually results in people requiring glasses with two different prescriptions, one for short and one for long-distance.
On bifocal glasses, there is a distinct line between the different prescriptions. Wearers have to look up and down to switch between the prescriptions they need, with long-distance prescriptions at the top and near vision at the bottom.
Aspheric lenses are different from spherical lenses.
Spherical lenses: The higher the strength of spherical lenses, the worse the visual experience, because the spherical lenses do not eliminate aberrations. Aspheric lens: it can greatly reduce the deformation of things and make people see more clearly and vividly. Besides, the eyes are not easy to get tired and the appearance is beautiful. It reduces the aberration of the lens and ensures a clearer field of vision.
When the parameters of the lens are normal, the optical center of the myopic lens is the clearest, and the peripheral part of the lens will be slightly deformed. So now the lens is designed with an aspheric surface. Under normal circumstances, the mainstream aspheric lens in the market has a reduced edge design, which is about 5 to degrees lower. The opposite edge of a spherical lens is higher.
