Hi Billy, I always get (even more) sensitive to light during cluster, and has been an occasional trigger. I have the brightness down and night modes on devices/TVs and tend not to watch the screen often during clusters.
A few years back I was given lithium to stop a cluster which (I believe) made me even more ill and super sensitive to any light - I could only go out after dark. I got some FL41 glasses (pink lenses that block blue light for migraine/stroke/concussion) and they made a huge difference in reducing the bruised/stinging feeling even after the cluster ended. I wear them less often now, but more when I'm under bright lights in offices, supermarkets or if it's overcast. I was lucky that a local optometrist let me trial them before buying. I think axonoptics do similar and may be cheaper.
Good luck
