Office lighting and screen glare frequently cause computer eye strain headache, computer use  in offices with LED and fluorescent lighting in particular. The light sensitive and those with fluorescent light sensitivity are particularly vulnerable as their problems appear to have the same cause: disproportionately high blue light content emitted by LED and fluorescent lights. This post draws from vision and work ergonomics science to suggest ways to reduce LED and fluorescent light headaches with five different types of blue filtering glare screens.

How to pick the best blue filter for your light sensitivity problem

Blue light filter selection is complicated. A blue filter may help you with many problems: computer eye strain (computer vision syndrome), LED & fluorescent light sensitivity, sleep disorder, age-related macular degeneration (AMD), light sensitivity (discomfort glare), visual acuity… But not every blue filter will produce optimal results given the specifics of your blue light sensitivity problem.

Best anti-glare screen protector: Glare-free computer lighting

The best anti-glare screen protector or anti-reflective filter could only be anti-reflective & glare-free computer lighting. In spite of the proliferation of anti-reflective and antiglare products computer glare and reflections continue being a major cause of Computer Vision Syndrome, i.e. eye-strain, tired eyes, irritation, red eyes, burning sensations, dry eyes, blurred and double vision (Computer vision syndrome: A review; Jour. of Clinical Ophthalmology and Research; Bali, J. et al. 2014). Anti-reflective & glare-free computer lighting is tricky, goes beyond buying and installing a computer light, and requires some fine tuning to your eyes. But antiglare computer lighting is possible and it is neither difficult nor expensive once you figure it out. Below the principles of anti-reflective & glare-free computer lighting are explained; some specific solutions and products are suggested. Continue reading →

10 blue light filters to relieve computer eye strain, help you sleep better, etc.

Computer eye strain (eye fatigue, computer vision syndrome) has also been associated with blue light emitted by digital display devices. Computer eye strain is a big problem if you are blue light sensitive and you need to stare at screens a lot (my case). Moreover, emerging research suggests that there are other longer term health hazards, e.g. retina damage, sleep disorder, depression, etc. Blue light filters are a possible solution to blue light induced computer eye strain. This post attempts to answer the following questions: How does blue light cause computer eye strain? What blue light filter options are there? How effectively do they filter blue light? Where can you get them? Continue reading →
