What kind of Myopia Sunglasses are Most Suitable for Summer?
The classification of myopia solar lenses is mainly divided into three types: color changing myopia lenses, dyed myopia lenses and polarized myopia lenses. These three lenses have a common advantage that they are suitable for all nearsighted frames and sunglasses with small radians, and combine sunglasses and nearsighted lenses into one, which is more beautiful.
Main features of color changing myopia lenses: color changing sunglasses are adjusted by the change of ultraviolet intensity index, which can meet the requirements of indoor and outdoor wearing and effectively prevent ultraviolet rays. However, if they are used for driving, the ultraviolet index in the car is usually unstable, and the color changing effect is not very ideal.
Main characteristics of dyed myopia lenses: the price of dyed resin lenses is relatively low and affordable, but ordinary dyed myopia resin sheets may not have a good anti ultraviolet effect if they are not coated with additional film.
Main characteristics of polarized myopia lenses: the advantages of polarized myopia lenses are that they can effectively prevent ultraviolet rays, and the price is relatively high, which is not suitable for indoor wearing. Moreover, currently, only polarized myopia lenses with refractive index of 1.50 are sold in the market, and for people with high myopia, the lenses will be thicker.
Factors to consider when choosing
In the appearance inspection, in addition to the fact that the lens can't have scratches, impurities, bubbles and stripes, ladies who love beauty must pay attention to the anti UVA, UVB and CE marks on the mirror or hangtag to play the role of anti ultraviolet.
Quality of the lens: place the lens about a foot away from your eyes, look at a fixed object through the center, and then move it up and down gently. If it is a flat lens, the object should not move. If the object moves with the lens or is distorted, it means that the lens is uneven and uneven. Such Sunglasses cannot be bought.
The shades of color, too light sunglasses have little filtering effect; But too dark color can easily affect vision. Generally, the tan, gray and dark green are moderate. Their filtering effect is better, and the scene seen after wearing the lens will only become dark without obvious color difference.
Whether a pair of sunglasses has the function of preventing ultraviolet rays cannot be identified by our naked eyes. The manufacturer's express commitment to the product is the only reference for consumers to buy Sunglasses with protective functions. We can see such explicit signs as "100% UV protection", "UV400", "blocking all ultraviolet rays" and "UV protection" on the labels and glasses front of some products.
When choosing sunglasses, you should not blindly follow the trend, but also choose the size and radian of glasses according to your face shape. In addition, when trying it on, you should also see whether there is a feeling of vertigo, so as to avoid accidents similar to vertigo caused by wearing inferior sunglasses. You should also see whether the dialysis degree is high, and it is better to have a polarization function.
