Why UV Protection in Sunglasses Matters More Than You Think

Many people buy sunglasses purely for style. But the most important function of quality sunglasses is protecting your eyes from ultraviolet radiation — and not every dark-tinted lens actually delivers that. At Vision Plus, we help customers choose sunglasses that work as hard as they look good.

What UV Radiation Does to Your Eyes Over Time

• Cataracts: UV-B radiation accelerates clouding of the eye's natural lens
• Pterygium: Fleshy growth on the white of the eye — extremely common in South India due to UV and dust exposure
• Macular Degeneration: Cumulative UV damage contributes to age-related central vision loss
• Photokeratitis: Essentially a corneal sunburn causing temporary but intensely painful vision loss

UV400: The Only Standard That Matters

UV400 means the lens blocks all light wavelengths up to 400 nanometres — covering both UV-A and UV-B completely. Every pair of sunglasses at Vision Plus meets UV400 standards. A dark lens without UV400 coating can actually be more harmful than no sunglasses — the pupil dilates in reduced light, allowing more UV radiation to reach the retina.

Polarised Sunglasses for Driving on GST Road

Polarised lenses eliminate horizontal glare from wet roads, car bonnets, and water surfaces. For anyone driving on the GST Road corridor or Chennai's coastal roads, polarised lenses significantly improve safety and reduce eye fatigue. Available at both Vision Plus branches.
