A software developer has tweeted about whereby wearing a VR headset for hours a day has ruined his vision.
A visit to the opticians gave him “worried about my future VR use” after a doctor accused the technology of a problem with his vision.
Glasses should correct the problem but would typically only “be designated to 40-year-olds”, he tweeted.
The Association of Optometrists announced it had not seen evidence that VR headsets could cause permanent eye injury.
Facebook-owned Oculus states in its handbook that one in 4,000 may suffer “dizziness, convulsions, eye or muscle twitching.” It recommends users experiencing these symptoms discontinue employing the headset and see a doctor.
Doctors have earlier warned that virtual presence, which is the computer-generated simulation of a true or imaginary environment, can cause eye strain because the mind is forced to process visual incentives in a different way to normal.
And users must complain about nausea and dizziness when utilising headsets, which is generally put down the way a user observes space around them, leading to motion sickness.
Danny Bittman, who has served as a virtual reality developer for four years, suggested it could have influenced his eyesight.
“Just had my primary eye doctor visit in three years. Now I’m apprehensive about my forthcoming VR use. I have a new eye convergence problem that acts like dyslexia. The doc, a headset owner, is demonstrated my VR use caused this. He said, “these glasses we regularly prescribe to 40-year-olds”, he tweeted.
He went on to explain the problem: “My eyes jump when I read things like a screen or books. I’ve always had a little level of this, but it’s greatly intensified now. It’s also connected to headaches and vertigo.”
He said that the problem was about “prolonged use” and admitted that he could use up to six hours a day wearing a headset, split into 30-minute sessions.
“However, some people do experience from temporary symptoms such as nausea, dry, sensitive eyes, headache, or eyestrain. “
But she did have some helpful advice: “If you spend all day in VR without a rest, you’ll need time to readjust to the light and the various visual environment of the physical world. I would suggest using a five-to-ten minute break each hour, doing that time to move about, blink and look out of a window, or take a small walk.
“The number of ampere-hours of headset use a person can comfortably tolerate will differ depending on your binocular vision situation (ask your optometrist) and the task you are doing in VR.”
VR headsets have been accommodated to help improve eyesight. Start-up GiveVision created a device called SightPlus, that aims to replace vision to people whose eyesight has deteriorated past repair by projecting a video of the real world into the practical part of the retina.
A clinical examination at Moorfields Eye Hospital suggested it enhanced eyesight in 59 of the 60 participants, with nearly half stating they would wear the device for watching TV, reading, or according to the theatre. The firm is partnering with Sony to improve its next tool.
