Snoop Dogg always wears sunglasses mainly as a fashion statement that reflects his unique style and personality. Additionally, the sunglasses provide functional protection from the sun's harmful UV rays. Beyond fashion and protection, sunglasses serve as a privacy barrier for him, shielding his eyes and perhaps hiding his inner emotions or truth from public view. His signature look with sunglasses has become iconic and a part of his public persona, boosting his confidence and making a bold style statement.
There are also some fans' humorous and speculative takes, suggesting he wears them because he is often high, or for a mysterious persona effect, but the key reasons are his style, eye protection, and privacy.
