Squint

Sitting in the passenger seat. The sun's glare made him lower the visor so he could see. Upon doing this, however, he felt that he saw less. The visor completely obscured his vision of the top right corner of the windshield. Squinting into the sun at least gave him the chance to fight against the shine. He decided then that he would rather struggle to see what hid behind the painful rays than be wide-eyed and comfortable and not see anything at all.
