> reading on an iPad literally makes me sick Being an active light source vs a passive one like Kindle/paper, the perceptual effect is different. Sickness could be coming from various causes, including: - you're holding it too close to you (which makes your eyes converge/accomodate too much): try to make the font bigger and put it further away (it will also reduce the resolution issue since you will have more pixels per arc-minute) - brightness too high: turn it down (!), use light text on dark background (hint: for e.g safari, use the iOS accessibility feature and bind it to triple home click or something to toggle it quickly), when possible choose colors with less contrast between text/background. - light sources around you: try to change relative light position or type of bulbs (CFC bulbs give me headaches for some obscure reason, while some LEDs one are too cold/blu-ish).
