Imperfect but forgiven
I have astigmatism, so if the bulb is anything other than an old type incandescent (not the new energy-efficient kind), I can't read because the print is fuzzy, jumps, rotates, swims, etc., and I get a horrible headache. Glasses or contacts don't fix it. Only surgery for cataracts and insertion of a specific type of lens will (according to doc, anyway). Unfortunately, my cataracts aren't anywhere near bad enough for the VA to take care of (yet).
One of the churches I go to has CFLs in some fixtures that makes it impossible for me to use a hymnal or read the Bible along when Scripture is read if I sit in certain seats/areas. Unfortunately, if Dad goes with me, this is where we have to sit because of his rollator and intense fear of getting "something" (worth it for Dad to go with me, though . . . he actually went with me to accept the invitation for anyone in the cogregation to get up and sang the Hallelujah Chorus with the choir on Resurrection Sunday!)
Warm white LEDs aren't as bad as cool LEDS, halogens, "energy-efficient" incandescents, CFLs, or even regular incandescents, but for reading and other similar distance tasks, in the wrong lighting, I'm essentially blind It's even worse than the humming and screeching of every fluorescent bulb (and some LEDs) on the planet. Astigmatism, the completely avoidable, "new" disability, caused by "going green"
Have you tried pricier LEDs? Ones that can be dimmed seem to be really good. The ones marked "economy" or "contractor" are very unstable and would give anyone a headache. One of the first things I did in the Cheyenne home was convert from incandescent to LED and applied lessons of buying higher quality bulbs that I learned from my mistakes in the Alaska home. I prefer LEDs just because they use less electricity and I'm a cheapskate...
