			It's the reason I don't have a Nook Color.  If I need to read in the dark, I make sure my Calibre Library is always up to date with my Dropbox, and use my smartphone.  I can go for short bursts on my smartphone LCD screen (Droid X) but not extended periods.  I even use a book light or my nook at night.

 There are two other brightness control menus, but they only adjust the overall system brightness. Use the menu listed above to lower the brightness even lower for books only. BTW, if you know how to strip the DRM and use calibre to convert/modify ePubs, you can change all text to BOLD via modifying the CSS. It is rather complicated so I won't cover the technique here, but search in the MobileRead forums for instructions. I modify all my ePubs to use BOLD text because my eyes are not that good either. I find that the bold text helps significantly for both the NC with its LCD as well as eInk screens.  |

			Just a random thought, I was dealing with eyestrain issues and solved the problem by turning the brightness UP. This increased the contrast between the letters and background and is much easier on my eyes. I know it's counter-intuitive, but it might be worth a try.

			I believe Calibre has plugins that will do this for you.  See the Calibre forum for more information.

 Using low brightest and grey/sepia backgrounds is hard on the eye. What I resort to reading on is using night mode (Black background and white fonts) this helps reduce the amount of light at night but keeps the fonts crisp. Also don't hold the nook so close. This part is completely personal, but I found that when I had the nook up close the pixilation of the fonts annoyed me and strained my eyes. Once I started placing the nook farther from my eyes the strain went away and so did the visible pixiels. I did not experience this kind of strain with my LCD phone or my Kindle 2. =X=  |

 In response to the OP.. 1. Don't root the NC to try to solve your eye strain issues. It'll possibly prevent you from being able to return it if necessary. (At the least it will add extra work to do so) 2. Do you have issues looking at a computer monitor for any amount of time? If so, you may as well take the NC back now. If not, then there's no reason you should be having issues with the NC. Try a non-white background, increase the font, line spacing, whatever. You have it, you may as well tweak them to see if they help. Personally the 'night mode' (white text on black backgrnd) makes my eyes want to scream so I would never recommend that mode. Sepia is great though. It could just be you're one of the odd few that can't look at LCD's long (computer or otherwise). Some people are alergic to plastic. Go figure.  |

 Below that is pictures of line spacing and margins. Then at the bottom is Publisher Defaults - on or off. Font and page color show one choice - tap on it and scroll up and down to see other choices.  |

			NoName, are you looking in a book or just in the NC Settings? If you're just looking at NC Settings that might be the reason you can't get your brightness down to a comfortable reading level. What you need to do is open a book, tap at the bottom, and you should get both font and brightness choices.

			Hi belle2be  to change the color of the background : Open up your book you are reading or any book for that matter 
		
	
		
		
		
		
		
		
		
		
		
		
		
			1.tap the middle of the page 2. a tool bar should pop up on the bottom (content, search, share,text, brightness0 3. tap text 4. a pop up display box should appear, the top will have the A ranging in 6 sizes underneath you should see to long boxes first will will have your font style (ie mine is Georgia) the second long box should have your background color. ie normal 5. Tap on the second box (mine right now says normal) 6. A listing will appear for different backgrounds. 7. you finger scroll through your selectionss my advice would be to try gray or night until your eyes adjust to reading on an lcd Hope this helps and if something doesn't make sense please let me know and I try to explain it better.
