Marc Walks pure titanium rimless glasses
The detailed processing lets you experience the perfect quality. They areβ titanium pure titanium ultra-light rimless myopia glasses, the new silica gel temple tips, and rivet design, and they will not deform with many twists and turns. The silicone material is safe and non-toxic. They have a non-screw design, so installation is not loose, and the lens is stable and not shaking. The lens is not in direct contact with metal and is not easy to break. The degree is not limited, so 1500 degrees below can be installed.
Do night driving glasses really work?
Yellow lenses reduce the amount of light entering your eye, reducing visibility. These darker colors block more blue light than yellow lenses. But they block more light from entering the eye, reducing visibility even more in low-light conditions. In fact, even yellow lenses reduce overall visible light to some extent because they block some blue light. This can be a good thing during the day, but not at night, when maximum visibility is key. Night driving glasses come in a variety of yellow and amber colors. The darkest lenses filter out the harshest light, but they filter out the largest amount of light, making it difficult to see in dim or dark conditions. Some people who wear night driving glasses say they can see better with them on. However, vision tests have shown that night driving glasses do not improve night vision, nor do they help drivers see pedestrians any faster than they would without glasses.
What are night driving glasses?
Night driving glasses are usually non-prescription glasses with yellow lenses and can be bought in many optical stores or online. Lenses range in color from light yellow to amber, and some night driving glasses have an anti-reflective coating. The yellow night driving glasses have been manufactured and sold for decades. They were originally sold to hunters as shooting glasses because they gave birds a sharper contrast to the sky on overcast or overcast days.
Have regular professional examinations.
The rimless glasses frame is directly punched on the lens and fasteners are added to fix the lens. It is easy to loosen the lens after long-term wearing. Therefore, it is recommended to regularly check and correct the glasses in the store when wearing rimless glasses. If the protective nut of rimless glasses falls off, stop using them immediately and repair them in time before wearing them. If screws and other accessories are loose, etc, be sure to go to the optical shop by the professional processing division to adjust.
How are we nearsighted?
The light from external objects to the eye needs to be refracted by the lens before it can be imaged on the retina. The refractive power of the lens depends on the contraction and relaxation of the ciliary muscle. When we look at close objects, the ciliary muscles contract and the lens becomes thicker. When we look at distant objects, the ciliary muscles relax and the lens becomes thinner. Adjust the focal length of near and far objects so that they will show a clear image on the retina. If you use your eyes too often and the longer the ciliary muscles work continuously, the ciliary muscles will spasm because of too much tension. At this time, the lens cannot be adjusted and thinned. After the light from a distant object is refracted by the lens, the imaging position will fall in front of the retina instead of on the retina. Only a blurred image can be seen, which becomes myopia.
There is another situation. For some people, due to genetic factors, in the process of growth and development, the front and rear wheelbase of the eyeball will gradually become longer. In this way, although the adjustment function of the ciliary muscle and the lens is normal, the image formed will also fall in front of the retina due to the longer the axis distance of the eyeball, which can also cause myopia.
The two causes of myopia are different. Myopia caused by ciliary muscle spasm is called 'pseudo-myopia'. As long as the ciliary muscles are relaxed, myopia can be reversed. Myopia caused by the extension of the wheelbase of the front and back of the eyeball is called 'true myopia', which cannot be reversed and can only be corrected by myopia glasses.
Gunnar Intercept blue light blocking glasses
The company is committed to improving people's visual experience when watching digital devices like computers, laptops, smartphones, pads, etc so that the wearers will no longer be affected by harmful light like short-wave blue light and glare refracting from these digital screens. They are continuously pursuing better protection of human eyes. Gunnar Intercept anti-blue light glasses filter or block harmful blue light from screens like computers. They relax eye muscles, soothe eye fatigue, prevent eye dryness, maintain constant moisture, and increase visual clarity.
Choose cost-effective lenses.
People who have high degrees choose the lens with a high refractive index like 1.60. So that the child's nose will not be compressed, which is the concern of most parents. Children grow faster, and the glasses replacement cycle is short. Adults should choose better quality lenses when choosing lenses, because a pair of glasses can be used for years, even in the situation when the frames are badly distorted and the lenses turn yellow. Zeiss A series lenses are cost-effective, suitable for people who are short of money and want quality. Nikon lens quality is very good, the film, wear, and sharpness are excellent. The disadvantage is that it is expensive, and the price gradient is quite large. The price scope is a bit wide, with two different refractive indexes.
