Digital self-assessment application for identifying ADHD Symptoms
ADHD is a common neurobehavioral disorder, diagnosed by clinicians using subjective tools, sometimes supported by a computerized test, with many cases remaining undiagnosed through adulthood. There is a need for objective tools for ADHD preliminary self-assessment, prompting seeking professional clinical diagnosis if relevant. Here a short, self-administered tool based on dynamic crowded visual stimulation developed by GlassesOff was used to identify ADHD symptoms in 24 ADHD subjects aged 16-28 years, compared to 18 controls aged 20-30 years. The observed large and significant visual acuity reduction in ADHD subjects compared with controls, equivalent to about 2 ETDRS lines, suggests that this digital tool may be used for objective assessment of ADHD symptoms.

Vision improvement in pilots with presbyopia following perceptual learning
Israeli Air Force pilots continue flying combat missions after the onset age of presbyopia. Optical corrections limit their flying capabilities. GlassesOff was applied to improve pilots’ near visual acuity (VA). Despite their advantage of 0.26 logMAR (P = 0.001) in VA for brief presentations (120 or 60 ms) compared with 152 age-matched controls, pilots improved after training (P = 0.01), most of them reaching the level of young controls with no significant difference (P > 0.05). Gains were generalized to higher functions, such as reading. Training with GlassesOff was effective for overcoming blurred vision, with real operational benefits. AAO 2014
Digital precise remote near visual sharpness evaluation on mobile devices
GlassesOff developed a tool for precise remote evaluation of near visual sharpness in order to accurately and remotely estimate reading abilities. Tested on 73 volunteers on iPhone 4, the application better predicts the functional reading acuity due to the brief stimuli presentation, as opposed to single letter detection used in golden standard reading chart measurements.

Brain plasticity overcomes presbyopia – persistence over time
Earlier results showed that perceptual training on PC and mobile devices improved UCNVA by ~ 2.5 ETDRS lines. In 60 presbyopes that were trained at 40 cm, for 15-30 min/ session, 3 times/week, the improvement of the UCNVA continued for 6.22 years (average 2.45 years), despite the natural deterioration of ~0.5 Diopters and 2 ETDRS lines expected during this time. Perceptual training overcomes the continuous effect of natural deterioration of vision in presbyopia by enhancing image processing in the brain. AAO 2013
Perceptual training on mobile devices improves near visual functions
The resolution and quality of smart phone screens are much better than those of PC monitors, with an average pixel size several times smaller in Apple’s retina display than in PC screens. This enables one to achieve better contrast sensitivity by a factor of 2-3, thus providing more prospect for training near visual functions. ARVO 2012
Perceptual training on mobile devices for the aging human eye
Training with GlassesOff on mobile devices is an effective solution for improving near vision sharpness in presbyopia by enhancing image processing in the brain, with better contrast sensitivity compared to PC. AAO 2012
