after wearing (monthly) disposable plastic contact lenses for around 2-3 hours yesterday, my left eye developed a foggy, blurred vision, with color distortion, "rainbows" around lights and generally significant lack of sharpness. There is also an enhanced sensitivity to the eye, and minor feeling of dryness. There is no pain to speak of. The problem did not improve overnight. The right eye is perfectly fine. I have not experienced this before, though I have worn these contacts previously.
--> Could this be a corneal edema? If so, should I act on it, or can I expect it to improve by itself within a few days? If not, what could it be?
Many thanks for your help,
