Virtual Reality Glass is a tool that allows users to experience virtual reality technology (VR-Virtual Reality) including content such as images, videos, games ... right on the smartphone.

When wearing glasses, users feel like they are in the scene, are seen and interact. Sometimes a virtual battle, underwater world or space. Applications and front-facing kits (3D).

What is the effect of VR on the eyes? Many parents allow their children to participate in this movement without anticipating the harm.

Adults wear also find it uncomfortable

Nguyen Tuan Anh (25 years old, Ho Chi Minh City) said: " I have used VR virtual glasses, although glasses have different focal lengths that can be adjusted to suit each person's eyes. I feel pretty tired ".

Tuan Anh said when wearing, the entire glass will cover the entire eye to cover the back of the head so there is no light in it. In addition to the video, images, and games designed specifically to represent the environment of virtual reality VR glasses, they are very eye-catching colors. Although the glass "cling" tightly to the head, difficult to move to stabilize image but when wearing new will feel very uncomfortable because unfamiliar with viewing images in completely dark space.

In addition, the eyes will be glittering like the feeling of the house is out of power, eyes are accustomed to the dark, the lights suddenly glow. Sometimes I feel a bit dizzy.

After a virtual reality glasses borrowed from you, Minh Thong (a student at HCM City University of Technology) said that he had a red rash over the exposed skin area. Cong said that glass material made the allergy.

For children to use, be careful

TS.BS CKII Trinh Thi Bich Ngoc - former deputy director of Hanoi Eye Hospital - said that the nature of virtual reality glasses is to stimulate the function of the visual - photo receptor function - of the eye more active. The use of this glass, but with those who suffer from visual impairment, 3D animation effect will be reduced significantly, even the 3D effect is not visible.

In terms of eye protection, only with the form of television viewing on the television, the safe distance to help the eye is healthy is 3m or more and not viewed continuously more than an hour.

With the use of virtual reality glasses, this time must be shortened because 45 minutes - 1 hour is the eye activity is fatigue, the ability to regulate the eyes soon exhausted, eyes need rest, letter Stretching if not will be prone to refractive errors.

For children, parents really need to consider when using this type of glasses because young eyes are in the stage of development and complete functions. Every day, young eyes have to regulate a lot for learning, exploring the world around, watching television ... now have to regulate much to see the image in the glass is easy to overload eyes.

At a time when there are no formal studies on the effects of this glass on the human eye, especially the young eye, it is best for parents to restrict their use.

Not to mention, on the market today there are many types of glasses of this type with many different production sites, the product cost from several tens of millions to the product cost only a few hundred thousand. Therefore, it is difficult to avoid the use of poor quality glass and harmful, easy to cause eye diseases.

Why do manufacturers have to put an age limit?

According to Reena Mukamal, Eyehealth, AAO, most VR devices produced around the world indicate they are not suitable for children under the age of 12 or 13.

Using a VR device or any digital device over long periods of time can cause fatigue and irritability. That's because users will tend to blink less than other eye activities. This causes dry eyes and eyestrain.

Users with dizziness and a sense of motion drift because seeing a motion-related image will give the brain a constant visual signal, which the brain continuously records in real motion. This explains why using VR or leading to dizziness.

If the user is motion sickness, nausea or motion sickness, there is also the risk of being "virtual reality".

If somebody is suffering from blurred vision (binocular vision is not equal) or the eyes are squashed or some other pathology leads to loss of ability to focus and sense depth, can not have three-dimensional sense, will not You can experience 3D effects or use VR technology. This does not mean that visual disturbances are caused by VR technology.

However, children or adults with these disorders will often have headaches, eyestrain when using the VR.
