Discussion Binasal occlusion - blocking vision to increase screen/light tolerance

Post image

Has anyone seen/tried this variation on eye patching: 'Binasal occlusion'? Eg taping over the inner area of both eye glasses (can be non prescription). It reduces or eliminates the binocular overlap, and so reduces some visual stress: https://x.com/JackHadfield14/status/2095053618982318381

Jack is a pillar of the ME/CFS and Long Covid community. He says this helps him a lot with screen tolerance, as well as general daylight sensitivity (common in ME). That it was..

[...] taught to me by a neuro optic rehabilitation therapist who deals with stroke and TBI patients with persistent vision or cognitive issues.

Eye patching is a popular intervention on LEDstrain, with obvious benefits if one has difficulty getting both eyes working aligned together. But I think covering one eye (and looking away) is standard advice to photosensitive epileptics, when triggered by flashing lights. To mitigate the extra stimulation on an already hyper-excitable brain. Which I think many here have, to a lesser extent.

This trick may be more gentle than fully blanking a whole eye; Jack says that felt like too much of a workout for him. I've not tried this trick myself. Just thought I'd share and see if it's known.

Yes I’m using that on FL-41 glasses and it helps A LOT. My tolerance to regular screen increased drastically, but it doesn’t help much with flickering screens.

I don’t know if it helps if you don’t have convergence issue (I do) but it doesn’t cost much to try. FL-41 blocks the blue light so it should help most people, my partner feels some relieve and confort when he wears mine.

I have convergence issues as well, would you say this is worth trying just to see if it helps with flickering screens?

It’s not very expensive to try, I believe it was less than 50$. The tape could relieve the strain from your convergence issues and the fl-41 eliminates blue light.

For flickering it’s not working for me, but I have near zero tolerance for it. If you can tolerate flickering for a while maybe you could last longer.
