Key screen adjustments include matching brightness to your ambient lighting, setting moderate to high contrast for text clarity, enabling blue light filters or night mode during study sessions, and increasing text size for comfortable reading. Experimenting with these settings during practice sessions helps identify the configuration that works best for you, significantly reducing the risk of eye strain during the actual exam.

Proper ergonomic setup involves placing your monitor at least an arm's length away with the top of the screen at or just below eye level, allowing your gaze to fall slightly downward. This reduces neck and shoulder strain while promoting a relaxed viewing angle that eases eye workload. Supporting this with an adjustable chair with lumbar support and soft, indirect lighting further minimizes physical stress and visual discomfort.

A diet rich in vitamins A, C, and E, along with omega-3 fatty acids from foods like leafy greens, carrots, fish, and nuts, helps maintain optimal eye function. Staying properly hydrated and getting 7-9 hours of sleep each night allows your eyes to rest and recover. Regular physical activity improves blood circulation to the eyes, while stress-reduction practices help reduce overall tension that can exacerbate eye strain.

Blue light filters reduce exposure to blue light, a wavelength associated with eye fatigue and disrupted sleep patterns. Most modern devices include built-in blue light filtering settings, and third-party applications can automatically adjust color temperature based on the time of day. These filters work alongside other strategies like anti-glare screens, proper screen calibration, and break reminder apps to create a comprehensive approach to minimizing eye strain during extended digital test preparation.
