Sunglasses in Sri Lanka are an essential accessory to have, especially since it is a tropical country with sunshine all year through. Purchasing a good pair of sunglasses online in Sri Lanka, can help protect your eyes from the sun’s harsh UV rays, while adding style to your ensemble.

Why UV Protection Matters

UV (Ultraviolet) rays from the sun can damage your eyes over time. Prolonged exposure to UV rays has been linked to various eye problems, including cataracts, macular degeneration, and even eye cancers. Therefore, wearing men’s or women’s sunglasses in Sri Lanka that offer adequate UV protection is essential for maintaining eye health.

Understanding UV Rays

1. Types of UV Rays:

• UVA: These rays penetrate deep into the skin and eyes, contributing to premature aging and skin cancer. They are present throughout the day, even on cloudy days and can penetrate glass.
• UVB: These rays are responsible for sunburn and can also cause eye damage, including cataracts and growths on the eye's surface. They are more intense during midday and summer months.

1. UV Protection Levels:

• UV 400: This designation means the lenses block all UVA and UVB rays, up to 400 nanometres. It provides the highest level of protection available in sunglasses.
• UV-A/B: Some sunglasses may only specify protection against UVA and UVB rays separately. While effective, UV 400 is more comprehensive.

Choosing Sunglasses for UV Protection

Check the Label: Look for a sticker or tag that indicates the sunglasses provide 100% UV protection or UV 400 protection.

• Lens Material: Most lens materials, including polycarbonate and high-index plastics, inherently block UV rays. However, coatings can enhance UV protection.
• Polarisation vs. UV Protection: Polarisation reduces glare from surfaces like water or roads but doesn’t necessarily include UV protection. Ensure sunglasses are labelled for both UV protection and polarisation if needed.

Tips for UV Protection

• Coverage: Choose sunglasses that cover the entire eye area, including the delicate skin around the eyes.
• Wraparound Styles: These styles offer additional protection by blocking UV rays from entering the sides.
• Regular Replacement: Over time, scratches and wear can compromise UV protection. Replace sunglasses periodically, especially if you spend a lot of time outdoors.

Additional Considerations:

• Children’s Sunglasses: Children's eyes are more sensitive to UV damage. Ensure their sunglasses provide adequate UV protection.
• Lens Colour: While darker lenses can provide comfort in bright conditions, UV protection is not determined by lens darkness. Check for UV-blocking capabilities regardless of lens colour.

By choosing women’s or men’s sunglasses in Sri Lanka with proper UV protection and taking care of your eye health, you can enjoy the outdoors safely and reduce the risk of long-term eye damage from UV exposure.
