My eyes in pictures - one flashes red, the other white?!
Question: My eyes in pictures - one flashes red, the other white?
HOWEVER, in the last few months, I've had 3 pictures taken of me on different nights, different lighting, etc, and the SAME (my left) eye is flashing white while the other is still flashing red. Has anyone heard of this being dangerous in adults? I'm 29.
I'm not usually in many pictures, so I would say all of the pictures I've seen of myself in the last 2 years have had a noticeable difference in my eyes.

Don't be too concerned about this. The red/white reflections are just artefacts... I'll explain:
Red eye reflection is cause by the flash gun of a camera that is failry close to the lens (most non-professional cameras). The light from the flash hits the eye, goes through your pupil (usually large coz the picture is taken at night) hits your retina (the nerve layer inside the eye) and bounces back through the pupil again... and into the camera lens. Now because the retina if full of blood and blood vessels, the reflection appears RED.
The white reflection: in a particular photo... if you're not looking directly at the camera.. but about 15 degrees left or right of the camera... the flash light going into your eye hits your optic nerve head, which is a part of your retina that hasn't got any blood supply, just a few blood vessels. Because it hasn't got much blood supply, it reflects WHITE light, instead of red... simple as that.
The white flash that you hear of in babies is VERY DANGEROUS, as it is either Congenital Cataract, or worse... Retinoblastoma which is a life-threating cancer. But if you've never had either of these, and your vision in both eyes are good, then the white reflex in your eye is nothing.
If you don't want red/white eye reflection in your photos, take photos with a professional camera (SLR) that has a separate flash gun.. and if possible, point the flash gun up to the ceiling...
