![]() ![]() The company said in a statement that it denies allegations that it cuts corners to verify prescriptions or has engaged in manipulative marketing. The FTC allows something called 'passive verification', in which sellers send prescriptions to eye doctors and - if they haven't heard back in eight hours - they can sell their product.Īdditionally, Hubble was found to have sold contact lenses to people who entered fake prescriptions and nonexistent eye doctors into the order forms, reported Quartz. 'Research shows that a Dk/t of 24 is necessary to maintain cornea integrity and avoid swelling,' she writes.Īdditionally, as it turns out the company has used a loophole from the Federal Trade Commission (FTC) to avoid regulation. ![]() But the Dk/t of Hubble contacts is only 18, according to a blog post from Dr Claudia Lee, an optometrist from Whitby, Ontario, Canada. The ideal Dk/t - the method used to measure how much oxygen contact lens wearers are receiving - is 24. Hubble has used a loophole that lets sellers send prescriptions to patients if they haven't heard back from the doctor within eight hours. Several studies found that lens wearers were suffering from corneal hypoxia, meaning there was decreased oxygen flowing to the cornea. One problem may be that the material Hubble used to make its lenses - Methafilcon A - is rarely used anymore. For sure, people that do will be wrought with problems.' 'You are buying a lens without the advantage of trying it on. The biggest problem with this lens is, for many people, it won't be comfortable and the reason for that is because it won't fit right. 'There is no such thing as a generic contact lens,' he said. 'They see it's a great price and see the bottom line.'ĭr Thomas Steinemann, an ophthalmologist at MetroHealth in Cleveland, Ohio, told it's important to remember that contact lenses are medical devices. ![]() 'They're just assuming the lenses they get from Hubble are the same thing I prescribe them,' Dr Lodholz told the newspaper. You're not the first'.ĭr Lauren Lodholz, an optometrist from Lexington, Kentucky, says more than half of her patients have reported problems after wearing Hubble lenses. She told The Times that when she told her ophthalmologist she was using Hubble contact lenses: 'They said, 'Oh, that's it. She was diagnosed with uveitis, which occurs when the middle layer of tissue in the eye wall become inflamed.Īnd Bailey Brown, from Dallas, Texas, developed a corneal ulcer in one of her eyes just lat month. Hubble also requires that buyers enter their prescriptions in the order form, which they then verify with ophthalmologists or optometrists.īut several users have complained of being left in debilitating pain after using the lenses.Īshley McCormick, of Hackensack, Minnesota, told The Times that one morning in January 2019, she woke up, barely able to open one of her eyes. Even while it was in safe mode, NASA said its “instruments are still fully functional and are expected to produce excellent science for years to come.” Hubble’s successor, the James Webb Space Telescope, is scheduled to launch in 2021.The lenses are made from a material that is hardly used anymore, which was found to reduce the flow of oxygen to the cornea. The Hubble Space Telescope has helped scientists discover troves of new planets, make a 3D map of dark matter in the universe, and shed new light on the mysteries of black holes.Ī joint project of NASA and the European Space Agency, it was originally meant to last 15 years, but has been in operation more than 28. The telescope was put into safe mode and suspended its science collection activities on October 5 while Earth-based engineers tried to fix the problem.Īn attempt to revive the gyroscope by turning it in the opposite direction appears to have cleared any blockage, NASA reported late Monday. Two others like it have already failed, NASA said, of a total of six on the telescope which has been circling the Earth since 1990. The gyro was one of three in active use and had been acting up in recent months. ![]() The problem came from one of the pieces of equipment on board known as a gyroscope, which helps point and orient the telescope. NASA’s famed Hubble Space Telescope is nearly back to normal after a failed orienting tool forced engineers to put it in safe mode earlier this month, the US space agency said. ![]()
