“People with myopia or high myopia need to be extra careful, including those who have a history of detachment in their families. Sudden flashes of light, black spots and blurry vision should not be ignored, especially by such patients,” he said. Sanjay Dhawan, director of ophthalmology at Fortis Memorial Research Institute in Gurgaon, says that people with myopia should get regular eye check-up done. “Prevention is always better than cure. If not diagnosed and treated at the right time, it can lead to blindness. Getting early medical aid and surgery is the best way. In such surgeries, holes are created to reattach the retina, which is then sealed with laser,” Dhawan said.

Could Google Glass Hurt Your Eyes? A Harvard Vision Scientist And Project Glass Advisor Responds
Peli has been conducting research on the use and impact of head-mounted displays for two decades, and he has been consulting with the Glass team for nearly two years. They approached me before they really got started because they knew that safety and comfort were going to be important parts of their project, Peli said in an email. All told, the results we see so far are encouraging. The head-mounted displays I have worked with prior to this one have been just thatdisplays where you could play videos or computer games. Glass is designed for interaction and communication, which is what people want. Peli said that Glass has a more advanced design for safety and comfort than any of the previous head-mounted displays Ive evaluated. He noted that the glasses have a very minimal impact on the wearers field of vision, so that there was little chance of Glass putting a wearer at physical risk of bumping into objects. Theories about potentially serious consequences likeconfusion or disorientation were raised in the media and had echoes in the literature in the 1990s, butthey were associated with virtual reality type displays that completely enclosed the viewer, Peli wrote. Most importantly, the devices that academicswore years ago were very different in fundamental ways from systems like Glass, despite what a casualobserver might perceive as superficial similarities.
