Why Are Ski Goggles Mirrored?

How about the optician center at Walmart?

Sixty-four percent of American adults wear prescription glasses, more than 157 million people. Since Walmart is the largest manufacturer of finished prescription glasses in the United States, the glasses are likely to come from Walmart. In reality, it's the only product they produce from start to finish. The ultimate goal of Walmart Glasses is to serve more customers faster and with better quality.

The optician center is not very big, but there are many kinds of glasses frames, and Walmart is the big backing, so the quality is relatively reliable. There are famous brands of lenses, a little more expensive, but certainly cheaper than the nearby optical stores. And you can pick and choose.


How to adapt to progressive lenses?

People who are prone to motion sickness or have inner ear diseases may suffer dizziness, nausea, vomiting, and other symptoms due to their inability to tolerate the slight deformation of the visual objects, so they need to pay more attention when wearing them. For people who have not worn reading glasses before, it is not recommended to wear graded multi-focus glasses directly because their eyes will not be able to adapt quickly.

The correct method for lens cleaning

Wet it with water first, and then add a little detergent or hand sanitizer to each lens. Dip your fingers to the back of the lens, and then scrub with your fingers. Be careful not to use too much force to prevent the lens from being worn out by grit.

The key here is to rinse. First of all, never use hot water, because hot water will cause the lens to expand due to heat, which will crack the film in the resin lens.

Finally, you should rinse with cold water, do not wipe with a cloth, because any glasses cloth or suede can not perfectly wipe the lens, even the more you wipe it, the more indistinct it gets. If there is hard dust in the cloth, it will scratch the lens.



The origin of aspheric lens

The Visby glasses, unearthed in Gotland, Sweden, are the earliest aspheric lens found. The Vikings in the 11th century used it as a magnifying glass, and some of the best ones were made of silver, making them look like handicrafts. In 1667, Francis Smethwick grinds the first high-quality aspheric lenses and presents them to the Royal Society. That's a telescope with three aspheric elements. In 1956, Elgeet, which originally designed and manufactured optical instruments for the U.S. Navy, produced the world's first mass-produced aspheric lens for photography (Golden Navitar 12mm F1.2) for a 16mm film machine. Today, aspheric lenses are found in everything from tall telescopes to missile guidance systems to camera lenses. In the glasses we wear, the aspheric lens is familiar to consumers.
