Feirdio blue light goggles
It can reduce the visual fatigue and discomfort caused by surfing the Internet for a long time, playing games, and working under fluorescent lights, and has the effect of protecting and reducing glare. The low color distortion lenses are optimized to provide the perfect balance for blue light prevention and visual quality. They have blue light prevention, glare reduction, UV blocking, screen flicker prevention, electromagnetic ray blocking lens. The frames of these blue light glasses are made of TR90 material. They're twice as durable as plastic glasses. These blue-blocking glasses are made of reinforced metal hinges to ensure durability and avoid cracking.
Different styles of glasses
If the style of new glasses is different from the old glasses, the angles of the glasses are also different. So the new glasses will cause visual differences. The symptoms of dizziness after wearing the new glasses will occur after a short period of time. If you adapt, you should be able to return to normal.
In order to avoid discomfort in wearing glasses due to inaccurate optometry, experts suggest that myopia should choose a professional eye hospital for medical optometry. When the glasses are damaged, they should be replaced in time to avoid injury to the eyes.
The Disadvantages of Glasses Without Prescription
In this section, we will list some of the disadvantages of glasses without prescription. Even if you are a good candidate for non-prescription glasses, professional advice is recommended. It is not recommended to buy higher values without medical advice. If you need a different correction for each eye or have astigmatism, prescription lenses are more suitable.
Why do you need rimless glasses?
Traditional full-frame glasses can sometimes make your face look heavy, especially if the lenses are thicker. Rimless glasses can replace heavy frames without weight from the rims. This reduces the pressure on the nose pad, making your face feel lighter and more comfortable.
Why the lens coating is not uniform?
Sometimes we find differences in the color between the convex and concave surfaces, between the center and the edge of the lens, and the anti-reflection effect between the convex and concave surfaces. his is mainly because the lens coating is that it is plated on one surface and then turned over to another surface. And Areas with small curvature changes are easy to coat. So the center of the lens has reached the desired thickness of the film but the edge has not. At the same time, the different curvature of the convex surface and concave surface causes the different coating speed. So the surface of the lens will show green in the center and lavender red or some other color at the edges.
Contact lenses or glasses, which is better?
The choice between glasses and contact lenses is a matter of personal preference. Lifestyle, comfort, convenience, budget, and beauty should be all the factors in your decision. Each approach has its pros and cons in terms of vision, ease of use, and eye health. So deciding that if you wear contacts or glasses, and when, is often a matter of personal preference. But Keep in mind that if you wear contacts all day, you should have up-to-date glasses in case you need to stop because of an eye infection or irritation.
Which is better, Essilor lens or Zeiss lens?
1. Different high-density resin substrates. Essilor Diamond Crystal series 1.74 lenses use resin with a density of 1.46 as raw materials. The lens itself has higher hardness. Combined with Diamond Crystal series film layers, the lifespan of the lens is better improved. The outstanding abrasion resistance is obvious.
2. Different technical support. The greater the density of the lens, the harder the substrate. However, the larger the density of the lens under the same volume is heavier. Therefore, Zeiss has the best trade-off between density and component and selects high density on the basis of high refractive index and frivolity substrates.
3. Different Features. The anti-fog molecules on the two surfaces of the lens are activated by an anti-fog activator. Therefore, the fog differentiates into a thin layer that is invisible to the eyes, instead of forming a fog. Each spray of activator can last about a week. Zeiss resin lens guarantees up to 99.4% of the lens light transmittance, and the naked eye can no longer feel whether the lens is worn or not.
