Start with a frame size that fits your face shape and a style that matches your wardrobe. For red lenses, choose a tint depth that suits your usual lighting, and decide if you want polarized lenses for glare reduction.

Key factors include lens tint depth and shade, 100% UV protection, polarization if glare is a concern, frame material and size for comfort, and overall coverage to block light from the sides.

Think about how you’ll use them—daily wear, driving, or outdoor activities—and whether you need lightweight materials, prescription compatibility, or easy-care coatings.

For driving, prioritize polarization to reduce glare and a comfortable frame. For hiking or outdoor use, choose a wrap style with durable lenses and a tint that preserves contrast.
