This topic is technical and vague at the same time, therefore, I will try to summarise my experiences and any potential solutions as best as I can, based on my research.
Approximately 6 yrs ago, I suddenly developed dizziness, migraines, eye strain, sometimes sea sickness symptoms. I discovered this was from flicker in led, energy saving, fluorescent lighting and digital displays and screens. Walking in supermarkets, using my old phone etc would trigger the issues.
I was seen by numerous opticians, a neuro ophthalmologist, two migraine specialists, (the latter recommended medication), in general I did not get far. I also spoke with professors, a screen manufacturer too for clues.
I tried software like f.lux, Truview overlay by crossbow education, monitor shields from the same company, some of these solutions worked for a short period only, till the issues occurred again.
I have read supplements may help, e.g. increasing magnesium, cayenne pepper, however have not tried these.
As a result of the above, and my research, I currently use a standard projector to watch TV on, use halogen lighting where possible, not energy efficient, however is easy on the eye.
I use Eizo EV2450 monitors, with the correct settings, which do not cause me eye strain. https://www.eizoglobal.com/products/flexscan/ev2450/index.html#tab01
I use a modern Amoled Xiaomi mobile phone which has an option to turn off flicker, this mode works well for me.
Lastly and most importantly I saw an optician who took my issues as a challenge, and between us, we came up with a specific green/yellow tint for glasses I currently wear, which help a great deal. I’m not saying this solution will work for everyone, (some specialists said coloured lenses have a low success rate, others recommended FL41 type pink tints), however, for the last 4 years or so, mine have made a massive difference. I can tolerate most environments and digital screens, (bar modern 4k monitors), which I’m working on. (I’ve tried 3 that are advertised as flicker free, one had DC dimming, however still no joy).
I also live a healthy lifestyle, getting to bed at a good time makes a difference too, along with consistent sleeping/waking patterns everyday.
Hope I can help with the above,
BTW, I’ve not put details of my optician, as I don’t want to be seen as advertising or promoting a service. However, if there is enough interest, I don’t mind sharing his details, he is UK based, in the North West.
Please bear with me too, if my replies are slow, or there are a lack of them.
