I always wondered about the chrome book. I assume you like it?
turning on sepia, large fonts, and dim the screen the Emerson's matte quality screen comes pretty close in bright light to a e-ink. migraines are caused by few factors in me. too much backlighting, OLED screens, and low DPI. usually a combo of the two or three need to be in play for a device to give me headaches. the Emerson meets none of those criteria for browsing an occasional e-book for an hour or two per day.
After some rather nasty migraines after an hour of Pinball Arcade on my PlayStation Vita, i have stopped using it.
My eyes are super sensitive to bright backlights and grainy pixel quality. that's something i would expect is normal. the Vita is an OLED screen that is, even on the dimmest brightness setting, super bright. it's a good way to get headaches if playing games or reading sites with very tiny fonts. it does not help that it is such a tiny screen and i strain reading microscopic data in a game such as my score or in a FPS game, the HUD.
since this issue is not happening on the retina display, or the higher-resolution LCD on my laptops, i do not think it is my eyes. besides, last time i did get an exam i had 20-10 eyesight.
having eye strain or headaches is not a life threatening illness so i do not see any grounds for why Sony would get a lawsuit. maybe for epilepsy perhaps but most games if not all have that warning on screen before you open them now.
Actually, on the subject, the Nintendo 3DS did have tons of cases of kids having problems after extended play with the 3-D screen, but i do not recall Nintendo having any lawsuits against them, either.

I expect there's similar warnings, legalise and disclaimers in the Sony PSP manuals as well. Ever noticed how laptops, PCs, monitors, keyboards, mice, etc. often come with extensive warnings and health advice?
WARNING - Seizures
Some people (about 1 in 4000) may have seizures or blackouts triggered by
light flashes or patterns, and this may occur while they are watching TV or
playing video games, even if they have never had a seizure before.
• Anyone who has had a seizure, loss of awareness, or other symptom linked to
an epileptic condition should consult a doctor before playing a video game.
• Parents should watch their children play video games. Stop playing and consult
a doctor if you or your child has any of the following symptoms:
Convulsions
Eye or muscle twitching
Loss of awareness
Altered vision
Involuntary movements
Disorientation
• To reduce the likelihood of a seizure when playing video games:
1. Sit or stand as far from the screen as possible.
2. Play video games on the smallest available television screen.
3. Do not play if you are tired or need sleep.
4. Play in a well-lit room.
5. Take a 10 to 15 minute break every hour
WARNING - Repetitive Motion Injuriesand Eyestrain
Playing video games can make your muscles, joints, skin or eyes hurt. Follow
these instructions to avoid problems such as tendinitis, carpal tunnel syndrome,
skin irritation or eyestrain:
• Avoid excessive play. Parents should monitor their children for appropriate play.
• Take a 10 to 15 minute break every hour, even if you don't think you need it.
• If your hands, wrists, arms or eyes become tired or sore while playing, or if you
feel symptoms such as tingling, numbness, burning or stiffness, stop and rest
for several hours before playing again.
• If you continue to have any of the above symptoms or other discomfort during
or after play, stop playing and see a doctor.
• When using the stylus, you do not need to grip it tightly or press it hard against
the screen. Doing so may cause fatigue or discomfort.
