Difference Between Sunglasses and Optical Frame Glasses
Sunglasses are basically applied to block sunlight and adornment effect. But in the choice of lens material and lens craft respect, it is not very particular. Correspondingly, consumer wears for a fixed number of years, to be in one season or two seasons. Sunglasses are sold with obvious seasonality. Optical glasses are mainly suitable for the use of photometric glasses. Both the lens material and the production process have higher requirements. A panchromatic or half chromatic resin lens is added to an optical lens, and then they can be sunglasses and can try luminosity, made of myopic sunglasses.
Best Eyeglasses For Women - Chanel
Chanel glasses inherit the consistent tradition of Chanel brand. The elaborate design of the style can be clearly seen from its detailed carving, innovative technology, and excellent lines and contours. In addition to the elegant logo, the glasses themselves appeal to the public with their sharp silhouettes and avant-garde designs and colors. Chanel is the lofty yearning in the heart of every woman. Its thin and light frame, streamlined design, increasingly foil the wearer's eyes.
Blue light blocking glasses lenses and common glasses lenses have different colors.
The real blue-light-blocking glasses should be yellow. Based on the primary principles of optics, the light reflected from the lens is the light that resists the same color as it. As the name indicates, blue light is to prevent the reflection of blue light. Remove blue light, and all the red, yellow, blue, and green in visible light is yellow.
Can I order progressive glasses online?
Glasses belong to the half medical and half business industry, in addition to the price of glasses, frame style, lens quality, there is more need in professional glasses services. The quality will be very different. The refractive index, film layer, light transmittance, and anti-oil resistance of the lenses almost invisible to the naked eye will be very different, so the prices of different brands of glasses are not comparable. There are many considerations when buying progressive glasses online. If the lens is too far away from the eye, people with myopia may not be able to see clearly, and people with hyperopia may have too much diopter. If the distance is too close, the opposite is true. In addition to the accuracy of optometric data, we need to pay attention to the importance of frame to maximize the benefits of the progressive lens.
Replace the nose pad on your glasses
Remove the screws clockwise and use a toothpick to remove the things left of the broken pads so that the new one can be installed. The next step is to fix the nose pad that we just removed from it. Hold the glasses and then the hole for the nose pad is up, then place the nose pad in and press it with your finger. Then you can see that the round hole in the nose pad overlays with the round hole in that part, and at this time, you can turn the screws. When you finally turn it, you usually turn it three times to hold the nose rest in place. Often, the nose pad can be swung back and forth after installation. This is to match the different shapes of our noses.
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.
Bertoni polarized glasses
Bertoni polarized night vision driving glasses are made of strong, flexible, durable, and ultralight polycarbonate. Yellow polarization increases contrast, improves visual acuity, and filters out blue light. They are great for drivers, cyclists, and winter sports enthusiasts. The driving glasses with polarized yellow lenses block glare from headlights, reduce night driving glare, improve night vision, and improve color clarity and visual clarity. They are ideal for driving in low-light conditions. Most sports sunglasses glasses frames and goggles are made of polycarbonate because of their strong, thermoplastic, lightweight, and impact resistance features.
