IT WOULD BE REALLY HELPFUL IF YOU WOULD HAVE OPTIONS FOR HIGH CONTRAST OR INVERT COLORS ON YOUR VIEW MENU OR AT LEAST AN OPTION FOR A BLACK BACKGROUND PAGE. ALSO, ANOTHER VIEWING ISSUE- TO BE ABLE TO CHANGE THE COLORS FOR MENU ITEMS AND FONTS ON THE PROGRAM OR AT LEAST BE ABLE TO CHANGE SKINS. I HAVE DIABETIC RETINOPATHY EDEMA IN SHORT I CANT SEE LIGHT COLORED TYPE (WHICH IS USUALLY A FAINT GREEN OR YELLOW) ON A BRIGHT GLOWING WHITE BACKGROUND. SO BECAUSE i HAVEN'T FOUND A WAY TO CHANGE COLORS, I CAN'T USE ACROBAT TO VIEW. I HAVE HIGH CONTRAST COLORS SET UP IN MY COMPUTER SETTINGS BUT IT HAS NO EFFECT ON CERTAIN PROGRAMS AND ACROBAT IS ONE OF THEM. LUCKILY, I FOUND ONE FREE VIEWER THAT HAS THE OPTION TO INVERT COLORS ON THE VIEWING MENU CALL EVINCE BY GNOME. IF I HADN'T HAVE FOUND IT, I REALLY COULDN'T FUNCTION IN DAY TO DAY COMPUTER TASKS LIKE SIMPLY PAYING BILLS OR GOING OVER BANKING TRANSACTIONS AND WOULD BE VERY TIME CONSUMING TO SAY THE LEAST.
