i honestly dont know but i do know that being on the laptop or even staring at my lighted phone screen for too long a period of time makes my eyes ache and that just adds more to the pain. since i have daily migraines at this point it is really hard to avoid and I only use the laptop on days that my heads not as bad. anything above a 4 on the pain scale and i just dont mess with it. i know lighting is a maj trigger for me and if i spend more than 15 to 20 mins in fluorescent lights i'm most likely gonna be crying.
good luck :)

I think it varies from person to person, but from my experience, it's not too bad if I'm just on for a bit or on and off. Otherwise, it could potentially trigger migraines and make them worse. If you already have one, I'd recommend staying off until it eases up. Unless the migraine is stress related and you need something that requires using a laptop/ipad/etc to calm down; such as talking to someone, a certain movie or show, that kind of thing. That's the one exception I can think so, since stress is awful on migraines, so relaxing is really important.

Everybody is different, but I find if I'm on my iPad or kindle too long it makes my vision more blurry and aggravates my degenerative disk disease in my neck. I've found that setting a timer for around 20 minutes, then getting up and walking around, getting some water, or whatever, helps. I also hold my iPad upright so I'm not bending my head and looking down into my lap. I move my head frequently from side to side, too while I'm on it.

For me the rain and change in weather always make my migraines worse. I just dread it when the weather changes and the barometric pressure changes causing the migraine.

Sometimes I get a little bit of eye strain on my iPad. But it's never caused a migraine. I also don't spend hours at a time on it. Maybe 30 minutes at a time.

I don't have an iPad, but I have a computer. There is no wishy washy answer from me about this. If I have even a slight headache, and I go on my computer, well BAM! Pressure in my eyes turns to the feeling of someone stabbing me in the eyes. Then the light sensitivity hits hard. The only thing I can do at that point is put down all electrical devices, turn off the TV, turn off any music or stop whatever noise I may be hearing, and then lay down. Sometimes with an eye mask on.

But I may be an extreme case lol. Some people are good just by closing their eyes. But no, you are not the only one!

Oh! One thing you may want to look into. There is a company called Theraspecs. They make glasses with a special tint that is GREAT for when you are looking at the computer, tv, or iPad. I think the tint is FL-41. They are expensive, but I think the tint is somewhere between a dark pink and orange. If you go shopping, maybe you can find a dark pink tinted pair of glasses.

Hope that helps!

I think it just depends on the person. I do the same thing when I have a migraine. I know that the strain on my eyes will make the pain worse, but it's so hard to sit around and do nothing. I will watch tv, surf the net, or play games on my phone while I have a migraine. It is possible that the light is just making your pain worse. Light doesn't affect every person, but it is one of the major triggers.

When my migraine is really bad, I limit my time on the computer. But I can use my Kindle for longer because I can control the brightness on the Kindle. So when a headache gets worse, I just lower the brightness and that helps.
