GLARminŸ Tester is the answer to the question many of you ask: Which blue blockers should I buy. It is eyewear (see below – fits also over prescription glasses) with 8 interchangeable blue light filters. It is simple to use: Find the filter that works best for you. Next, consult this table to find the closest matching blue light filter. Finally, click on the product’s link in the table to go to the vendor’s site and purchase whichever blue blocker you are after: glasses, screen protectors, flip-ups, fit-overs…
After contacting T’aime to obtain spectral transmission data for the post on best blue blockers they offered to send me their Dinodon computer glasses for review. According to T’aime, the lenses on Dinodon’s filter 97% of blue light. Below you will find my thoughts after wearing the glasses for 4 weeks and the follow-up after another 8 weeks later. The focus of this review is on the lens effectiveness in blocking blue light and glare from computer (digital) screens and their ability to reduce computer eye strain and/or insomnia.

Do you regularly feel exhausted but can’t sleep? Tired eyes? Maybe you’ve noticed increased glare and light sensitivity? You probably have a screen based job. Moreover, after work you feel so tired you can’t but relax: read, watch TV, play video games, shop online, etc. But in doing so you rest your rested body (at work you mostly sit) and exhaust even more your already tired eyes (they’d been working very hard all day)!? Wouldn’t it be nice to be more productive at work and simultaneously more rested and upbeat during and afterward your workday? It can be done! Fight the effects of sedentary lifestyle and sedentary work with computer work in motion.
This post suggests that eye fatigue and photophobia should be added to the list of health risks associated with sedentary lifestyle – the sum of overall sitting time (screen based work, TV viewing, sitting in cars, …).
More importantly, the post proposes several ways you can set up your computer workstation to be physically active while you work. Continue reading →
This post might help you if have central serous retinopathy (CSR), sometimes also referred to as central serous choroidopathy (CSC). Because of CSR Sam (the name has been changed) had severe problems with light sensitivity to computer screens and fluorescent lights (but not other sources of light). He found relief in filtering blue light.
If you also suffer from central serous retinopathy and have issues with glare do drop a comment below, for the benefit of others who are also struggling with CSR related light sensitivity. Let us know what has and what hasn’t worked for you!
Disclaimer: My interest in blue blockers comes from my problems with light sensitivity (photophobia), discomfort glare, and computer eye strain.

Many people must spend virtually their entire work day at a computer. In addition, many of us spend several more hours using a computer for personal activities: email, shopping, researching topics of interest, and so on. As a freelance writer and editor I found that Computer Vision Syndrome crept up on me over a period of a couple of years after about ten years of very intensive computer use. My eyes were very dry and burning; my vision was blurry; I had constant headaches; I became very sensitive to light both indoors and outdoors. My discomfort and poor vision became so severe that I really wondered if I could continue in my work. That was a sobering thought, and it motivated me to learn as much as I could about my eyesight and how it is affected by a computer.
In this article I will describe some strategies that can make a significant difference in eye comfort for writers, editors, and others who work mostly on a computer with an emphasis on customizing Microsoft Word for maximum clarity and comfort. Continue reading →
Saying that “blue light blockers don’t distort color” is manipulation used to convince uninformed people to buy products that filter blue light, but not much and not any more than it filters the rest of visible light spectrum. But to prevent or mitigate eye strain, glare, insomnia, etc. a filter should block either most blue light or considerably more blue light than it blocks other, longer wavelengths of visible light. Such a blue light filter necessarily distorts color!
With the help of a few spectrograms you’ll see below why it is possible to say deceivingly – but without lying – that blue blockers don’t distort color.
