Does anyone know why you tend to squint more on certain overcast cloudy days than you do when it's really sunny ?

The light from the sun is scattered by the vapor in the clouds.
On a normal sunny day, most of the brightest sun rays travel to your eyes in a straight line. On overcast or hazy days, the light still gets to your eyes because it's refracted and reflected off other things (mostly the vapor in the clouds, but also ground surfaces).

On overcast days, the light from the sun is spread out over the entire sky, so the brightness is everywhere. On a sunny day, the brightness is only in the direction of the sun itself.

Even on an overcast day, the suns rays are coming through the clouds and are even at times magnified by the moisture in the clouds.

well maybe because our eyes can adjust better to the sunlight than we can to the cloudy days . good luck .
