Which factors affect visual acuity? The factors determining visual acuity in a healthy eye are chieflyrefractive error, visual angle, illumination, or rather brightness, contrast and period of exposure. Subordinate factors are irradiation, color, glare, width of pupil, attention and fatigue. ...
yes, many displays now come with blue light filter features to reduce eye strain during extended screen time. they emit warmer colors, which are easier on the eyes, especially at night. should i use blue light filters all the time? it's recommended to use blue light filters, especially at...

On most monitors, brightness is not perfectly even across the entire screen. It’s usually the strongest in the center and slightly lower towards the edges. On some units, this can be very noticeable. For instance, in the example above, if you were to put a plain white background on the...
The iPad was kept on maximum brightness with the automated brightness setting switched off. The participant was asked to hold the near tests at their preferred working distance (which was measured using a tape measure) perpendicular to their direction of gaze, and to keep this consistent for ...
