From another med site:
Your eyes have different color pigment which give you color vision. When light hits the retina, the pigment absorbs the light which produces the sensation of color, but the pigment is used up. (Goethe was among the first to discover this phenomenon)
If you wake to sunlight or bright light to your eyes when they are shut, your eyes will see red light through your eyelids. The green and blue pigments are not used up.
When you open your eyes, you will see a greenish-blue hue to everything for a time, until your retinal cells recycle the red pigment - that takes a few seconds.
This has been bugging me for months now. I was afraid it might be a brain tumor or something equally hideous. How can so many people be having this happen without any eye care professionals knowing what it is?

I've just recently started having this same strange symptom - seeing everything bright green for 2-3 seconds after waking up from daytime snoozes. I'm a healthy 55 year old woman, on thyroxine but otherwise no health problems. I have a suggestion and wonder if others could comment.
For the past 3 years I've had to work a lot in sub-Saharan Africa, and find it difficult to re-acclimatize when returning to Scotland. As a result I've been drinking more tea (for warmth!) in Scotland and not much plain water - creating a problem of dehydration. The dentist also mentioned that my mouth is very dry. Could the problem be related to dehydration? I never have the vision problem when in Africa, where I drink plenty of water.
For the past year whenever I wake from a daytime nap everything is yellow and green but quickly changes back to normal. My EEG was normal. My eye doctor does not know either. About 5 years ago everything was turquoise then changed to other colors. I wound up in a psych ward and was put on different meds....but after I came home the yellow and green thing started and slowly built up to everytime I nap. Needless to say I did not complain
....smile. It is nice to know I am not alone.
