Filter by: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.
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.
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.
This study aims to evaluate the efficacy and safety of 3% Diquafosol Ophthalmic Solution for visual display terminal (VDT)-associated dry eye and to investigate the mechanism of treatment.
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.
