The technology made a successful debut in the Khalifa Stadium at the World Athletics Championships in Doha in 2019, where a delegation from the Tokyo 2020 Organising Committee (TOGOG) and the Olympic Broadcasting Service (OBS) first saw the spectacle in action and agreed to work on a similar light show for the Olympic Games.
People who want to start wearing blue light glasses should speak with an optometrist or ophthalmologist for recommendations.The women’s 100m final saw the introduction of a projection mapping light show to set the stage for one of the highlights of the Tokyo Olympic Games on Saturday night (31). The Food and Drug Administration (FDA) do not regulate blue light-filtering technology for glasses. Researchers have not investigated all of these glasses in clinical studies. Some online retailers offering blue light lenses include: Other eyeglass companies are also offering prescription glasses with blue light-filtering lenses.
Cyxus Blue Light Filter Computer Glasses.Uvex Skyper Blue Light Blocking Computer Glasses.The following is a list of some available blue light glasses: Several companies manufacture blue light glasses. Long-term studies are necessary to investigate the harmful effects, if any, of chronic daily exposure to screens.Īccording to both the American Academy of Ophthalmology and the College of Optometrists, there is currently not enough evidence to support the use of blue light glasses.
Computer vision syndrome, or digital eye strain, is a group of eye and vision problems that result from chronic exposure to screens.įurther study is necessary to determine whether or not devices can emit enough blue light to harm the eyes and vision. Some experts believe that instead of blue light toxicity, people may be experiencing symptoms from overusing technology. Researchers have not confirmed whether or not blocking blue light reduces symptoms following prolonged exposure to screens. Manufacturers of blue light glasses claim that they help reduce headaches, reduce eye strain, and improve melatonin secretion to reduce symptoms from blue light exposure. A small 2019 study suggests that blue light glasses may be beneficial for treating sleep disorders in people with Parkinson’s disease.Īlthough some studies may suggest that blue light glasses increase sleep quality and duration, other studies suggest avoiding the use of devices before bedtime altogether. Other researchers have demonstrated that exposure to short-wave light from devices before bedtime may disrupt sleep patterns. A 2017 systematic review suggests that there is not enough evidence to support the potential benefits of blue light glasses, and some advertisers have received fines for making misleading claims. Some experts suggest that the low levels of blue light emitted from devices are not hazardous, even with prolonged exposure. Experts cannot rule out a yet undiscovered risk of chronic, day-long exposure to LED and blue light. With the increased use of light-emitting diodes (LED), organic LED, and active-matrix organic LED in technology, people now have chronic exposure to blue light. Experts suggest that damage can occur with high doses of blue light but also with a longer duration of less intense exposure. Manufacturers claim that blue light glasses can prevent blue light from damaging the eyes.
