While the dark tint of a lens cuts down on bright glare so you aren't squinting, it's the invisible UV-blocking filter that actually prevents cellular damage to your eyes and the delicate skin around them.

Sunglasses lenses come in different types and colors designed for various lighting conditions and activities. Gray lenses reduce brightness while preserving natural colors, brown lenses improve contrast and depth perception, and green lenses provide balanced color accuracy with reduced glare. Polarized sunglasses lenses help minimize reflected glare for driving and outdoor use, while mirrored lenses offer extra brightness protection in strong sunlight. Choosing the right sunglasses lens color depends on your lifestyle, outdoor activities, and visual comfort needs.

To clean sunglasses properly, rinse the lenses with lukewarm water first to remove dust and debris. Then use a microfiber cloth with lens cleaner or mild soap to gently wipe the lenses and frames. Avoid using paper towels, tissues, or harsh chemicals because they can scratch lens coatings. Proper cleaning helps maintain lens clarity, UV protection, and the lifespan of your sunglasses.
