How Bacteria on Contact Lenses Cause Inflammation--Study Shows

"Research presented at the ASM Microbe research meeting demonstrates a new way bacteria can cause dramatic morphological changes in human cells," says Medical News Today. "Specifically, the researchers discovered that a common bacterial contaminant of contact lenses and cases can cause the formation of large bubble-like membrane structures on human ocular cells, which can contribute to contact lens wear complications and inflammation."

Almost 10 Million Americans Are 'Severely' Myopic

"A new study estimates that 9.6 million adults in the United States are highly myopic, or severely nearsighted," according to a post on Medical News Today. "Of those, nearly 820,000 have a degenerative form of the disease and more than 41,000 suffer a complication called myopic choroidal neovascularization that could cause long-term vision loss, with women at higher risk. The findings are being published online in Ophthalmology, the journal of the American Academy of Ophthalmology. This is the first large-scale study ever done to calculate the real-world prevalence of myopic choroidal neovascularization in the United States." Read more.

Lower Blood Sugar Less Retinopathy

People with type 2 diabetes who intensively controlled their blood sugar level during the landmark Action to Control Cardiovascular Risk in Diabetes (ACCORD) Trial Eye Study were found to have cut their risk of diabetic retinopathy in half in a follow-up analysis conducted four years after stopping intensive therapy. Investigators who led the ACCORD Follow-on Eye Study (ACCORDION) announced the results today in New Orleans at the American Diabetes Association annual meeting. The study was supported by the National Institutes of Health’s National Eye Institute (NEI).

New Flat Meta-Lens Could Replace Contact Lenses

"Researchers from Harvard University have developed a new type of flat lens that could replace more cumbersome curved glass optics currently used in a wide range of imaging appliances," reports the Christain Science Monitor. "'This technology is potentially revolutionary because it works in the visible spectrum, which means it has the capacity to replace lenses in all kinds of devices, from microscopes to cameras, to displays and cell phones,' Harvard professor and researcher Federico Capasso said in a university release. Professor Capasso was also the senior author of a paper on the new technology, published in the journal Science. Capasso's planar lens is capable of processing images of objects smaller than even the best current microscopes, using a titanium dioxide-based array of nanostructures. That oxide is already used in applications ranging from skincare to white pigmentation for paints, foods, and more, and was chosen by the researchers due to its ubiquity and capacity to process light."

Google's Contact Lenses May Not Live Up to Hype, According to a Report

"The signature product from Alphabet-owned life sciences company, Verily, is still a long way from hitting the real world," according to Business Insider. "The glucose-sensing smart contact lens that Google first announced in 2014 is still just "slideware" that doesn't exist outside of PowerPoint presentations, according to a former Verily manager who spoke to Stat's Charles Piller as part of a critical look at the company's current endeavors. The contact lens project aims to provide an alternative for people with diabetes who currently have to prick their fingers to test their blood glucose levels. Instead, the lens could monitor the glucose levels in their tears. But the Stat report questions whether the lens will ever be scientifically feasible." Read more.

South Carolina House and Senate Override the Governor's Veto of Legislation Banning Online Eye Exams

The South Carolina House voted to override Gov. Nikki Haley's veto of a bill banning the practice of offering prescriptions for lenses and contact lenses after an online exam. The original legislation banning the practiced was passed 100-1 last month. "Chicago-based Opternative launched its online service in South Carolina and dozens of other states nationwide last summer. CEO and founder Aaron Dallek said the company has hundreds of customers in South Carolina," reports the Kansas City Star. "Opternative offers $40 to $60 prescriptions — depending on whether customers want a single prescription for glasses or contacts, or a prescription for both — within 24 hours for people ages 18 to 45 with a computer and smartphone. Customers taking the test are asked to take a certain number of steps away from their computer screen, depending on their shoe size, and use the computer like a digital eye chart. A text message sent to a customer's smartphone allows it to be used as a remote control. Answers to multiple questions, along with medical records, are sent to a state-licensed ophthalmologist contracted by the company. Inconsistencies mean a prescription won't be written, Dallek said."

Visual Impairment Skyrockets as Boomers Age

"With the youngest of the baby boomers hitting 65 by 2029, the number of people with visual impairment or blindness in the United States is expected to double to more than 8 million by 2050, according to projections based on the most recent census data and from studies funded by the National Eye Institute, part of the National Institutes of Health. Another 16.4 million Americans are expected to have difficulty seeing due to correctable refractive errors such as myopia (nearsightedness) or hyperopia (farsightedness) that can be fixed with glasses, contacts or surgery." That's the start of a press release from NEI. Approximately, "1 million Americans were legally blind (20/200 vision or worse) in 2015. Having 20/200 vision means that for clear vision, you would have to be 20 feet or closer to an object that a person with normal vision could see from 200 feet away. Meanwhile, 3.2 million Americans had visual impairment in 2015—meaning they had 20/40 or worse vision with best possible correction. Another 8.2 million had vision problems due to uncorrected refractive error."

 The researchers were led by Rohit Varma, M.D., director of the University of Southern California’s Roski Eye Institute, Los Angeles, led the researchers, and JAMA Ophthalmology published the results just this week (May 19th).

Poor UV Filtration in Car Windows the Cause of Left-Eye Cataracts?

"An analysis of the ultraviolet A (UV-A) light protection in the front windshields and side windows of automobiles finds that protection was consistently high in the front windshields while lower and highly variable in side windows, findings that may in part explain the reported increased rates of cataract in left eyes and left-sided facial skin cancer, according to a new study." That's the summation from Science Daily. Read more.

Subconcussive Impacts Affect Football Players Vision

"In a study that included 29 NCAA football players, repetitive subconcussive impacts were associated with changes in near point of convergence (NPC) ocular-motor function among players in the higher-impact group, although NPC was normalized after a 3-week rest period, according to a study published online by JAMA Ophthalmology," notes Medical News Today. "The NPC measures the closest point to which one can maintain convergence (simultaneous inward movement of eyes toward each other) while focusing on an object before diplopia (double vision) occurs."

Get Your Scrips and Glasses Online--Without an OD

Opternative founders Aaron Dallek and Steven Lee, OD.
"The eyeglass prescription process is the latest health care service to be disrupted — and now optometrists are waging an all-out war against a startup that lets people do vision tests without looking away from their laptops," goes the Buzz Feed posting. "Less than a year ago, Opternative, a Chicago startup, began serving customers through its website. In that time, optometrist lobbying groups have successfully backed legislation that bans the company’s ability to operate in five states, including Georgia as of yesterday. Last month, the American Optometric Association complained to the Food and Drug Administration that the company’s service should be taken off the market and studied because it is allegedly operating without federal approval. In the same breath, the group likened startups like Opternative to the 'corporate equivalents of snake oil salesmen.'" Read more.

Vision Monday reported a few days ago: "Organized optometry won the latest round in its fight against online refraction when lawmakers in the state of Georgia enacted legislation last week which makes it illegal to issue a contact lens or spectacle prescription without an in-person, comprehensive eye exam conducted by a state-licensed practitioner."
