With the explosion of VR concept, VR equipment is well known by more people. If we want to experience this kind of virtual reality experience. You can use the current mainstream VR equipment. Whether it's a mobile phone or a computer VR. People need to wear corresponding VR glasses. There are many kinds of VR glasses on the market. Their quality varies from good to bad. VR glasses are objects that come into contact with the eyes. Many people worry that VR glasses will affect our eyesight.

VR glasses have "glasses + screen" imaging methods. The glasses are 2-3cm in front of us. The screen is 3-6cm away from the glasses. Virtual image imaging is about 25cm-50cm in front of eyes. If you wear a helmet to experience a game. Your line of sight will continue to focus at 25cm-50cm and cannot move. The field of vision is full of electronic display screens. After watching for a long time, the eye muscles will be tired. This is easy to understand. This is the same as we have been staring at the mobile phone and the computer. Over time, dry eyes and fatigue will occur. There is a certain reason why VR glasses affect vision.

1. Although the screen of VR glasses is close to the eyes. VR glasses use convex lenses, and the scenes you see are not close. What we see is something several meters or even hundreds of meters away. Such a statement may confuse you. In contrast, VR glasses are much less harmful than those lying-in bed watching mobile phones. If there are any negative effects. It is the refresh frequency. Especially VR products based on mobile phones. Because their refresh frequency is less than 60 frames per second. Users will cause motion sickness after watching it for a long time.

2. Time control. Although VR games and VR virtual reality can bring immersive experience to everyone. Everyone still needs to control the playing time. Of course, excessive addiction is harmful to the body. So, you should not indulge in VR.

3. I suggest not to use VR products for children under 12 years old. PSVR's product introduction warned everyone so. Children have poor self-control. Try not to use VR products for children. If you want to share fun with your children, you must use it with adults. You have to take care of the equipment. Avoid children from secretly taking them to play and becoming addicted.

VR technology is constantly evolving. UGP has also introduced VR glasses with adjustable degrees for nearsightedness. As VR technology matures, more and more products will come out. The idea that VR glasses affect vision is a bit one-sided. This is similar to the claim that excessive use of mobile phones and computers can affect your eyesight. When using VR products, we should be moderate and not indulge.
