Yes, you can wear them outside, but they will not do much. Blue light glasses are built for screens and indoor light. Clear daytime lenses barely filter anything outdoors, and amber lenses just make everything look dark and orange without protecting your eyes from the actual sun.
Outdoors, your eyes need UV and glare protection, so reach for real sunglasses, not blue light glasses. Save your clear Day lens for screen time inside and your amber Night lens for evenings. Think of blue light glasses as an indoor, screen tool, not sun gear.
