Are myopic sunglasses reliable?
"Myopia, bike to work in the morning, the sun is very dazzling, want to buy a sunglasses, found two glasses together, too heavy." I heard that there are suitable for nearsighted people wear sunglasses, may I ask it reliable?
Recently, I received such a question in the background. The sun is shining, the weather is getting warmer, and the "sunglasses season" is coming. Today, I will tell you about this nearsighted sunglasses.
Nearsighted sunglasses technology is actually very mature in the country, the reason why it will feel unreliable, largely because it is not very popular in the country.
In fact, the fundamental reason for the lack of popularity is that the price of nearsighted sunglasses is slightly higher than that of ordinary sunglasses.
In addition, although myopia sunglasses have two functions of myopia glasses and sunglasses, it can not replace ordinary myopia glasses used indoors, so many people feel that it is not cost-effective to buy.
But in fact, sunglasses are closely related to our daily life, after all, ultraviolet light is very strong all year round, the damage caused by ultraviolet light is great, such as cataracts and so on, have to prevent. And driving, sunglasses can be a good way to weaken the harsh lights such as high beams, urban high-rise light reflection, heavy rain will also form a large range of scattered reflection, myopia sunglasses with polarizing function can also filter these diffuse and reflected light, effectively alleviate visual fatigue.
So it is very necessary to buy myopia sunglasses.
At present, if you want to wear sunglasses, there are the following ways:
Clip: It has a certain convenience to use, but there is some trouble in the positioning operation of the clip, and it is not particularly beautiful, and the split design is not particularly convenient for storage and access.
Color-changing sheet: Add silver halide chemicals to the lens, so that the originally transparent and colorless lens, when exposed to strong light, it will become a colored lens, to do protection, so it is suitable for indoor and outdoor use.
Non-polarized myopia sunglasses: mainly use dyed lenses, need to choose a professional brand lens manufacturer in advance dyeing, the color will be more stable.
Myopia polarized sunglasses: In addition to the basic anti-ultraviolet function, polarized sunglasses also have anti-glare, road reflection light, water scale light, etc., suitable for driving, fishing, tourism, daily wear.
The disadvantage is that if the myopia degree is deep, the lens will be thicker, of course, you can also match the lens with a higher refractive index, the price is slightly more expensive, but the lens is relatively thin.
In general, like driving, cycling, sports people to use sunglasses, it is recommended to match myopia polarized sunglasses, the most suitable!
Myopia polarizing sunglasses selection: lenses can choose Zeiss, Seiko, Nikon, Mingyue and other brands polarizing lenses, frames according to style needs can choose Tyrannosaurus, Ray Ban, Pedi and so on.
