I learned today the reason eye doctors, be they optometrists or ophthalmologists, recommend you have someone available to drive for you after an eye exam that includes dilation of your pupils.
I had my annual (read: every 15 months, for some reason...) eye exam today and did not think about the fact that my eyes would probably be dilated for my normal vascular and and other checks.
Well once I was there it was a wee bit late to arrange someone to drive me soooo...
Ouch. What happened to all those cloudy, rainy, and dark days we had been having lately..?!?
Yowzy..!! How painful was that 15 minute drive home..?!?
You really come to appreciate what a complicated instrument the human eye is; how finely controlled, regulated, and powered it is. Normally the pupil easily constricts and relaxes to control the amount of light entering the eye. Use of topical eye drops allow the pupil to be artificially opened. The effect takes a few hours to 'wear off'.
Anyway... luckily no changes in the eyes and an uneventful drive home. I am now sitting in our darkened den/PC room while the effect wears off. Still squinting a bit, due to the ambient light and the monitor's glow.
An interesting chapter in what I learned today.
