MUSCULAR EYE STRAIN

Problem: Eyes are designed to change viewing distance often. Eye muscles flex the hardest when viewing near objects. Extended near distance viewing without breaks causes cumulative eye fatigue, leading to repetitive muscular strain and possible headaches or migraines.

Solution: Most GUNNAR lenses (GUNNAR Focus) bend light before it reaches the eye so images can be seen more sharply while eye muscles relax.

QUALITY OF ARTIFICIAL LIGHT

Problem: Artificial light from computer screens, mobile devices, and office overheads contains small bands of high-intensity energy instead of balanced, full-spectrum light. This artificial light is particularly heavy in high-energy visible (HEV) light found in the UV through blue part of the spectrum (400-450nm). Overexposure to HEV light has been shown to cause altered circadian rhythms, insomnia, and impacted serotonin levels—all common symptoms of Computer Vision Syndrome. Prolonged exposure to blue light may increase the risk of age-related macular degeneration (AMD) and potentially worsen existing retinal conditions.

Solution: GUNNAR Tints filter and balance the transmitted light spectrum by reducing HEV. In addition to protecting eyes from digital eyestrain and potential long-term retinal damage, the specialized tints also provide more visual performance by allowing the sensitive parts of the eye to work optimally, increasing perceived contrast.

GLARE AND VISUAL NOISE

Problem: Digital screen reflections and glare cause visual noise for the eyes. These distractions require additional strain to mentally sort between the desired image and non-desired light, potentially causing increased fatigue and headaches.

Solution: GUNNAR GSHIELD®, GSHIELD® Plus, and GSHIELD® Premium coatings reduce glare, reflections, and visual noise.
