Among a group of "lazy people" who love to play with digital products, a product called "refractive glasses" is quietly popular. It is said that as long as you wear "refractive glasses", you can not only read books and newspapers lying down, but also play with mobile phones and iPads. The tablet family shouted, "Where are the refracting glasses born because of the iPhone? I need it very much! It's so tiring to lie on the 'woven scarf'!"

  The "refractive glasses", which are called "a must-have weapon for homeowners" on the Internet, are actually a kind of "lazy glasses" that use the angle of refraction to make people lie comfortably and see things clearly. It is said that wearing "refractive glasses" Glasses", as long as you put the mobile phone on your stomach, you can easily play with the mobile phone while lying down.

   The "magic" of "refracting glasses" is mainly in the refracting mirror that can turn straight light into refracted light. The specially constructed lens can keep the user's viewing angle in the best viewing angle range no matter whether he is lying on his back or lying on his side. Inside, it is like reading in a sitting position, suitable for fashionable young people, middle-aged and elderly people, and bedridden people with limited mobility.

   Are "refracting glasses" really so magical? Dr. Yu from the Optometry Department of Ruijin Hospital explained, “This type of glasses made by using the principle of refraction is likely to reflect the contents of books or electronic product screens to the front of the eyes at 90 degrees through the mirror fixed in front of the frame. There's nothing magical about the lens."

Ophthalmology experts remind "lazy people" to be alert to the "hazards" of "refractive glasses". "Generally speaking, after the image is refracted, the aberration will become larger and the degree of restoration will be reduced. Wearing this kind of glasses for a long time will increase the fatigue of the glasses." , but it may lead to myopia deepening.” If the quality of the lens is not good enough, it may also reduce the light transmittance, because the image refraction requires high brightness, and the brightness will deteriorate after refraction. “It is not recommended for young people to wear it for a long time.”

"When using electronic products, pay attention to blinking more. You can also drop anti-fatigue eye drops to help keep the cornea moist, do eye exercises properly, and massage the eye acupuncture points to let the eye muscles relax quickly." For a wide range of digital products, Dr. Yu suggested that those who love to play should pay attention to vision protection, "It is also very important to reduce the use time and correct incorrect reading posture."
