not really... seeing things under sun is not equal to squirting ur eyes to focus the incoming rays it's just that much light coming, the intensity of light to be exact. that's why camera, given the same setup, gives sharper image under bright sun light I never get as tired playing outside as compared to squirting my eyes all the time just to focus in a room. sun light is just that intense, rooms lightings are much less intense.

Cameras only give a sharper picture in bright light because this allows you to reduce the aperture size. The image is not sharper if you increase the shutter speed instead of reducing the aperture. This is basic physics. Bright light is not magical. Squinting your eyes is a very poor approximation to what your irises are doing. The light collimation is not reduced uniformly in every axis and your eyelashes partially obscure the light.
