Is reflected sunlight on any surface otherwise than mirror or mirror-like surface safe for human eye? I can imagine mirror surface could reflect a lot of sunlight directly, making little difference from staring at the sun directly

How about reflected sunlight on white but obaque surface? Could it cause any adverse or unwanted effect to human eye
