My eyesight seems to have been getting worse recently. I’ve caught myself a few times closing one eye when reading dark text on a white background on a computer. Over the last few days the (very big) text on the Sky+ menus has confused my eyes, and again I’ve had to close an eye and look away. Reading a small manual for a new heart rate monitor today has the same effect.
From a photographer’s point of view, I’d say that each eye had a different “white balance”. My left eye has a cooler, more blue view, than my right eye that has a warmer, more red image. Of course my brain actually performs the “white balance” perception alterations so I only see this difference if I close one eye and then the other. An optician friend of mine did explain this to me once; the light to my weaker eye is shifted towards the red end of the light spectrum, but I can’t remember why. I think I’ll make an official visit to see her next week.
This is interesting timing: we’ve just finished the term that teaches the anatomy of the eye.
