Special glasses marketed to filter out blue light likely do not make any difference to sleep quality or eye strain from computer use, according to a new review of studies. Blue-light blocking spectacles have been increasingly recommended, often by optometrists, since the early 2000s. Eye patients are frequently prescribed these lenses in many parts of the world with a range of marketing claims existing about their potential benefits. Some of these claims include that the special glasses may reduce eye strain associated with digital device use, improve sleep quality, and also protect the retina from light-induced damage. However, researchers, including those from the University of Melbourne in Australia, say there is “substantial debate” about whether blue-light filtering spectacle lenses have merit in ophthalmic practice. The research, published in the journal Cochrane Database of Systematic Reviews, assessed data from 17 clinical trials on the benefits offered by these glasses for improving visual performance, providing protection to the retina, and improving sleep quality. The review assessed data from individual studies from six countries, each including five to 156 participants, and the period of time over which the lenses were assessed ranging from less than one day to five weeks. Researchers found that there may be “no short-term advantages” with using blue-light filtering spectacle lenses to reduce visual fatigue associated with computer use, compared to non-blue-light filtering lenses. They say it is also currently unclear whether these lenses affect vision quality or sleep-related outcomes. The research review could also draw no conclusions about any potential effects on retinal health in the longer term. “People should be aware of these findings when deciding whether to purchase these spectacles,” study co-author Laura Downie said. “Our findings do not support the prescription of blue-light filtering lenses to the general population. These results are relevant to a broad range of stakeholders, including eye care professionals, patients, researchers and the broader community,” Dr Downie added. However, scientists said the quality and duration of the individual studies part of the review also needs to be considered. “High-quality, large clinical research studies with longer follow-up in more diverse populations are still required to ascertain more clearly the potential effects of blue-light filtering spectacle lenses on visual performance, sleep and eye health,” Sumeer Singh, another author of the study, said. The potential mechanisms by which these lenses might help with eye strain, sleep, and protecting the retina are also unclear, scientists say. “The amount of blue light our eyes receive from artificial sources, such as computer screens, is about a thousandth of what we get from natural daylight,” Dr Singh said. “Filtering out higher levels of blue light would require the lenses to have an obvious amber tint, which would have a substantial effect on colour perception,” he added. But the new research did not find any consistent reports of adverse side effects from using blue-light filtering lenses.

Sam Altman will return to OpenAI after an agreement in principle was reached, the company has announced. Posting on X, formerly known as Twitter, OpenAI also announced a new initial board of former Salesforce chief executive Bret Taylor, the former US treasury secretary Larry Summers and Quora chief executive Adam D’Angelo. Mr Altman also posted, saying “i love openai, and everything i’ve done over the past few days has been in service of keeping this team and its mission together.” Last week the board of OpenAI, which created the ChatGPT artificial intelligence tool, said it had pushed Mr Altman out after a review found he was “not consistently candid in his communications” with the board. Greg Brockman, the company’s president and co-founder, who left in protest at Mr Altman’s sacking said on X: “Amazing progress made today. We will come back stronger and more unified than ever.” “Returning to AI & getting back to coding tonight,” Mr Brockman added. The previous board of directors, which included Mr D’Angelo and Mr Brockman, refused to give specific reasons to why they fired Mr Altman last Friday. This led to mounting pressure within the company to reinstate Mr Altman, including a threatened exodus of nearly all of the company’s 770 employees. Microsoft, which has invested billions of dollars in OpenAI, moved to hire Mr Altman and Mr Brockman on Monday. In a post on social media on Wednesday morning, the chairman and chief executive of Microsoft, Satya Nadella, said he is “encouraged by the changes to the OpenAI board”. “We believe this is a first essential step on a path to more stable, well-informed, and effective governance.” Read More Data protection watchdog warns websites over cookie consent alerts Employee data leaked during British Library cyber attack Half of adults who chat online with strangers do not check age – poll Businesses embracing generative AI but fear cyberattacks, survey finds Young Britons turning to AI chatbots for help with school and work – survey Police to trial use of drones as first responders to emergencies

Former Theranos CEO Elizabeth Holmes may have again stalled the date by which she must report to prison by filing another appeal of her fraud conviction. Holmes was convicted by a federal jury of defrauding Theranos investors last year and was sentenced in November to just more than 11 years in prison. Holmes’s attorneys asked that she be allowed to remain free on bail while she appeals her conviction, but a judge declined that request and ordered her to report to prison on April 27. Now, though, it seems the disgraced tech star might not have to begin her prison sentence until June at the earliest. On Monday, her attorney filed a new motion of appeal of her conviction — after which Holmes was granted an immediate stay of her prison-report date, according to NBC Bay Area. The state has 21 days to respond to the appeal, after which Holmes’s defence team will have a further three weeks to file a final motion. After the final motion is filed, the Ninth Circuit Court of Appeals will consider her legal fate. The appeal filed this week is considered a longshot, but while that process is ongoing it is believed that Ms Holmes will remain free unless a judge orders her to report to prison. Holmes was back in the news last week after The New York Times published a long-form profile of her that was panned by a number of readers for its tone and credulity. Some critics, including the poet and essayist Hanif Abdurraqib, noted that Black people convicted of felonies are rarely given the same space to pitch their reformations to the media that the profile gave Holmes. Much of the article focused in part on Holmes as a mother. The former CEO gave birth to her first child in 2021 and her second child sometime around the beginning of 2023. Holmes’s former romantic partner and business partner Ramesh “Sunny” Balwani was sentenced to just under 13 years in prison on conspiracy and fraud counts for his role in the Theranos situation. He began serving his prison sentence last month.
