Filter by:To evaluate the performance of Total 30® (lehfilcon A) contact lenses in patients using digital devices for greater than 8 hours per day 5 days per week based on subjective reported data.
This is a profit, multicentric, prospective, single-arm, open-label, non-pharmacological clinical investigation. Patients with diagnosis of moderate to severe dry eye disease with asthenopia and accommodative effort will receive MERAMIRT®, 1-2 drop per eye 3 times a day for 90 days.
The aims of this study were to perform cultural adaptation of the DESQ and provide information regarding the factor structure, reliability and validity of the instrument in Turkish speaking adults.
Safety and Efficacy of Medications for Migraine in Patients with Dry Eye Disease or Asthenopia
Evaluate the improvement of regulation of skin and blood index composition after consumption of Omegia® Softgel
The goal of this observational study is to determinate the association between DES and changes in binocular vision and ocular surface. in higher education students in the area of health technologies. The main questions it aims to determine the prevalence of Digital Eye Syndrome (DES); the association between DES and changes in binocular vision and ocular surface; whether the time of use and the type of electronic devices influences the degree and type of symptoms of DES; and to determine whether there is an association between the type of ametropia and the symptoms of DES. Participants will have to answer 3 questionnaires (the Computer Vision Syndrome Questionnaire; the Convergence Insufficiency Symptoms Survey, and the Dry Eye Questionnaire (DEQ-5)) and then they will perform an orthoptic assessment and an assessment of the ocular surface with the tear film Break Up Time (BUT) test.
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.
Computer vision syndrome characterized as a complex of eye and vision problem related with activities which increase stress for close to vision. It includes a group of visual symptoms which occur from the extended viewing of the digital screen, when the demands of the task exceed the abilities of the viewer. Computer vision syndrome is an umbrella term that envelops many eye and environment-related problem that happen when the viewing need of the task increase the visual capability of the computer user which cause inefficacy to focus appropriately on computer images. Computer vision syndrome is also known as Digital Eye Strain.
This is a single site, randomized, double-blind placebo controlled parallel arm study assessing the effects of 6 months lutein supplementation on cognitive and visual outcomes in healthy children exposed to excessive digital screen time.
Operational military personnel are increasingly using virtual or augmented reality headsets in the field or in training. However, these devices cause a conflict between accommodation (focus to see clearly) and vergence (alignment of both eyes on the object being viewed) that can be a source of visual fatigue and altered visual and perceptual abilities. Although techniques exist to limit this conflict for screen-based stimuli, the use of helmet visuals (or immersive headsets) adds technological complexity. Indeed, since accommodation on the screen of the helmet visual is impossible (i.e., distance too small) for the human visual system, lenses are used to virtually shift the image (referred to as a collimated image) so that accommodation can occur much further away. However, this material configuration also modifies the vergence, thus causing a conflict between accommodation and additional vergence that persists regardless of the attenuation technique used. In this study, the investigator proposed to modify the image display to take into account the technical features of the helmet to correct this techno-dependent conflict. This study is aimed at determining whether the setting recommended by the algorithm developed by the investigator limits visual fatigue better than the conventional setting recommended by manufacturers or a subjective setting controlled by the user.
