Sunglasses are a must-have for summer eye protection, but not all sunglasses are created equal. Look for lenses labeled with 100% UVA/UVB blocking or UV400 to ensure full-spectrum coverage. Without proper UV protection, you risk corneal sunburn, which can lead to serious conditions like cataracts and macular degeneration. Oversized frames are ideal as they shield the delicate skin around your eyes. People with lighter-colored eyes, such as blue or green, are especially sensitive to sunlight and should prioritize wearing sunglasses.
