Central serous retinopathy (CSR), Photophobia and Blue light

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!

Here is what Sam’s message: Continue reading →

How to change text and background color in Windows 10

Windows 10 has made life of those with light sensitivity and computer eye strain issues more difficult. In terms of text and background color adaptability to specific visual needs it is a step back when compared to Windows 7. But you can still have it your way. Below you may find detailed instructions on how to fully personalize your Windows 10 screen’s appearance to your, eye-friendly colors (anything, to any color).

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. The chaos of hype marketing terminology often hides more than it reveals which further complicates the selection process. Read on to find out: which wavelengths your blue filter should absorb/block, by how much, how to compare bluelight filters… Continue reading →

Are your eyes sensitive to light … or just blue light!?

Eyes sensitive to light!? Evidently I am talking about light sensitive eyes as in photophobia, light aversion, discomfort glare, pain, eye fatigue and computer eye strain induced by light and glare. Increasingly scientific evidence shows that eye sensitivity to light tends to be caused only by a small portion of visible light that carries most of its energy – blue light, i.e. High Energy Visible (HEV) light. This article:

  • highlights key scientific reports indicating that eye sensitivity to light tends to be caused by blue light
  • suggests a way to test if and to what extent your eye sensitivity to light is blue light induced
  • proposes solutions to help you improve your light sensitivity pain threshold and/or cope with your blue light sensitive eyes

Less light sensitivity, computer eye strain: BlueLight filtering diet

You can reduce computer eye strain and light sensitivity with diet! Light sensitivity and computer eye strain may be due to low macular pigment, your natural bluelight filter. Nearly 80% of Americans have this condition! Research shows that low macular pigment is associated with lower threshold of light sensitivity or discomfort glare (Enhancing performance while avoiding damage: A contribution of macular pigment; 2013). Moreover, since glare is a known computer eye strain cause (Computer vision syndrome: A review; 2014) low macular pigment, i.e. lower threshold to glare, may make you more prone to computer eye strain. Luckily macular pigment bluelight filtering capacity can be improved with appropriate fruit and vegetable diet or dietary supplements (Lutein and zeaxanthin dietary supplements raise macular pigment density and serum concentrations of these carotenoids in humans; 2003).
