Why should you choose thin lenses?
Regular lenses are great for low-prescription people, but for high-prescription people, high-prescription regular lenses are too thick and heavy, making them unattractive and have a poor wearing experience. For high-prescription people, we recommend that they choose thin lenses with a high refractive index because they are lighter and more attractive to wear. For any astigmatism above +3.00, we recommend 1.67 or 1.74 refractive index lenses because these lenses are aspherical in design, which means they are thinner, flatter, and lighter than standard spherical lenses, which reduces the magnification of your eyes to other people.
How do fishing goggles work?
When fishing in calm water, the light is straight to us. Because of the wind and waves on the water, there will be countless reflective surfaces, just like we face countless mirrors, leading to not clear float. For a long time, eyes will be very tired. Fishing sunglasses block the uncomfortably bright light and protect the eyes from UV damage. All of these functions are achieved by metal powder filters that 'select' light as it comes in.

What is the bifocal lens?
Bifocal reading glasses are characterized by distance vision correction in the upper part of the lens and near vision correction at the bottom. If you need help with both, that's great. This lens is designed to facilitate the working of reading glasses and standard prescription glasses, all in one frame. Glasses are recommended when you are diagnosed with presbyopia, and bifocals are usually the first choice. But for intermediate vision, bifocals are difficult because they're not close enough for the reading part of the lens, and they're not far enough away for the distance part of the lens. Bifocal sunglasses have no magnification at the top, and the reading ability is at the bottom of the lens. Bifocal reading glasses can be found anywhere reading glasses are sold, but they can be harder to find than full magnifying lenses.
Do blue light glasses really protect your eyes?
Scientists at the University of Kansas in the United States summarized the results of studies around the world in the past 30 years and pointed out that there is not enough evidence in human trials to prove that blue light is related to macular degeneration, and there is no test showing that blocking blue light glasses are related to macular degeneration. Moreover, experts from the University of S?o Paulo in Brazil have observed after five years that patients who use anti-blue light intraocular lenses after cataract surgery have no difference in the incidence of macular disease compared with those who use ordinary intraocular lenses.
Production technology of progressive lenses
In addition to the evolution in design, the production technology of progressive lenses is also constantly improving: the most representative one is the free-form technology. The emergence of free-form surface technology makes the production more flexible and rapid and can realize a more personalized design. For now, progressive lens design is done on the inside surface of the lens by a computer-controlled lathe, as if a master engraver could carve a piece of stone into a work of art.
