Watching 3D movies can "immerse" you in the experience—but can also lead to visual symptoms and even motion sickness, reports a study – “Stereoscopic Viewing and Reported Perceived Immersion and Symptoms”, in the July issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
Studies have consistently reported that women require reading glasses or bifocal lenses earlier than men. According to a recent Investigative Ophthalmology & Visual Science paper, the gender difference is caused by factors other than focusing ability, such as arm length or preferred reading distance, which should be considered when prescribing readers or bifocals.
A group of computer science students at Drexel University worked with students from the Overbrook School for the Blind to develop a set of smartphone apps. The team integrated current visual-assistive technology and also customized social media app interfaces for visually impaired users.
Scientists have found new evidence that people spot a face in the crowd more quickly when teeth are visible — whether smiling or grimacing — than a face with a particular facial expression. The new findings, published in the Journal of Vision, counters the long held “face-in -the-crowd” effect that suggests only angry looking faces are detected more readily in a crowd.
Viewing Facebook and Flickr photos on a smart phone are becoming common practice. But according to a recently published Journal of Vision study, pictures on the small screen often appear distorted. Vision scientists found that perceptual distortions occur because picture takers do not take their viewing distance into account.
A telephone intervention trial was associated with improvement in glaucoma medication adherence in both the treatment group and the control group but, when the two groups were compared, interactive telephone calls and tailored print materials did not significantly improve adherence, according to a report of a randomized controlled clinical trial published Online First by Archives of Ophthalmology, a JAMA Network publication.
Cerebral damage and retinopathy of prematurity appear to be independently associated with visual impairment among preschool children who were born extremely premature, according to a report published Online First by Archives of Ophthalmology, a JAMA Network publication.
Suppose someone told you that researchers had discovered that a major cause of vision loss is treatable, and that the most promising new treatment is—playing video games? It may sound far-fetched, but those are the conclusions of a special article, “Removing the Brakes on Plasticity in the Amblyopic Brain,” in the June issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
When people close their eyes, they can form mental images of things that exist only in their minds. Neuroscientists studying this phenomenon at medical schools in the Texas Medical Center believe that there may be a way to use these mental images to help some of the estimated 39 million people worldwide who are blind.
Mayo Clinic is first in the Southwest to treat evaporative dry eye using LipiFlow thermal pulsation system.
iPhones and other smartphones can be a huge help to the visually impaired, but only 15 percent of vision doctors are recommending them to patients, according to a study presented at the 2012 ARVO Annual Meeting.
Researchers hope to use fluorescent light bulbs to slow nearsightedness, which affects 40 percent of American adults and can cause blindness.
New findings from a Canadian research team suggest that not only is there a real connection between vision and other senses, but that connection is important to better understand the underlying mechanisms that can quickly trigger sensory changes.
The same technology used by astronomers to obtain clear views of distant stars is now being used by optometrists to perform incredibly detailed examinations of the living eye. An update on new developments in ocular imaging techniques—and how they may affect clinical vision care in the not-too-distant future—is presented in an article titled “Adaptive Optics Scanning Laser Ophthalmoscope-based Microperimetry” published in a special May issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
Sloppy shipping of a donated human retina to an Indiana University researcher studying a leading cause of vision loss has inadvertently helped uncover a previously undetected mechanism causing the disease. The discovery has led researchers to urge review of how millions of dollars are spent investigating the cause of a type of age-related macular degeneration called choroidal neovascularization.
Two drugs commonly used to treat AMD yield similar improvements in vision for patients receiving treatments on a monthly or as-needed basis, according to a study from researchers at the Perelman School of Medicine at the University of Pennsylvania.
Results from the largest genetic study of glaucoma, a leading cause of blindness and vision loss worldwide, showed that two genetic variations are associated with primary open angle glaucoma (POAG), a common form of the disease.
ARVO is pleased to host a presentation of the one-year results from the U.K.’s Inhibition of VEGF in Age-related Choroidal Neovascularisation (IVAN) study and the two-year results of the Comparison of Age-related Macular Degeneration Treatments Trials (CATT) trial.
Just because a driver has passed the motor vehicle administration’s vision test may not mean he or she is safe to drive. A recent study found that the frequency and distance at which drivers with moderate levels of blurred vision and cataracts recognize pedestrians at night was severely reduced, even when the drivers have passed the required vision test.
A national consortium of researchers has published new findings that could change the standard of practice for those treating Fuchs’ Endothelial Corneal Dystrophy (FECD), a disease characterized by cornea swelling that can eventually lead to the need for corneal transplantation.
