Active clinical trials for "Asthenopia"

To evaluate subjective visual performance and objective visual parameters when wearing ophthalmic lenses with extra power (+0.4 D or +0.6 D), and ophthalmic lenses with a selective blue cut filter.

The purpose of this study is to evaluate the potential for supplementation with black currant to support eye health among otherwise healthy adult women who spend 6+ hours per day using digital screens.

Correlating the accuracy of a refraction done over telemedicine to that of a standard refraction, with a study hypothesis that the results will be equivalent.

A retrospective and prospective study to determine if the use of ambient lighting during screening colonoscopy is well tolerated and if ambient lighting will help physicians maintain adenoma detection rates while decreasing symptoms of eye strain as the day progresses.

Evaluate the improvement of regulation of skin and blood index composition after consumption of Omegia® Softgel

Reading can be an uncomfortable and difficult task for some people. Symptoms include unpleasant somatic and perceptual effects, such as eye-strain, headache, and blurred text, despite normal visual acuity. This condition has been called Visual Discomfort, but little is known about the symptoms and frequency of reading problems associated with this disorder. Several studies have proposed that Visual Discomfort is caused by increased noise in the visual system due to spreading cortical activation across different spatial frequency channels. This study examines the prevalence and severity of visual discomfort in a college student population and tests the noisy visual system hypothesis.

Several recent clinical trials have highlighted the potential role of Product in promoting eye health.product whose structural and functional characteristics make it a promising bioactive compound in the prevention of several human diseases as well as in the maintenance of a good health status. it might relieve eyestrain in people using computer monitors as suggested who conducted a double-blind randomized clinical trial by enrolling visual display terminal workers and prescribed them product or placebo. Study outcomes were objectively evaluated by using a proper instrumentation to measure eye muscle endurance. Subjects receiving Product experienced a significant relief from eyestrain compared to the placebo group.

Children in the United States watch an average of twenty-eight hours of television and play around thirteen hours of video games per week. The objective of this experiment was to see if a specific eye exercises could strengthen the eye muscles and improve the peripheral vision range of children and adults.

Current virtual reality device makes motion sickness and visual fatigue having limitation for recreation and other clinical approaches. Still there is no standardized quantification of motion sickness and visual fatigue measurement with objective approach. Current biofeedback accompanied with virtual reality would be promising tool for stress relief.
