How to protect your eyes from the sun for Greater Independence in Everyday Life

Sunscreen shields our skin from UV damage, yet our eyes require light to operate, meaning some ultraviolet radiation inevitably reaches them. The eye's internal structures absorb much of this radiation without injury, but prolonged or intense exposure can still cause harm and raise the likelihood of developing certain eye conditions.

Cataracts represent one of the most well-known threats from UV exposure. This condition involves clouding of the eye's natural lens, gradually making vision appear misty and blurred over time.

Sunglasses serve as a primary defence against harmful UV rays by reducing the amount of ultraviolet light that reaches the eyes, making outdoor vision more comfortable while lowering long-term eye damage risk.

Always verify that sunglasses carry the CE quality mark or meet the British Standard BS EN ISO 12312-1, both of which confirm adequate UV protection. Lenses come in various tints, and the darkness or colour choice is largely personal preference — darker lenses do not automatically provide superior protection, nor do lighter ones offer less.

Larger lenses cover more of the eye area, offering better shielding, so selecting a pair with the biggest lenses that still fit your face comfortably is advisable. Wraparound designs additionally block UV rays from entering through the sides.

Price does not guarantee protection. A budget-friendly pair that includes a verified CE or UKCA mark and UV filtering is far more effective than an expensive designer option without those safeguards.

Even on overcast days, harmful UV rays can penetrate cloud cover and reach your eyes, so a UV filter remains essential regardless of weather. Most prescription glasses include a built-in clear UV filter, so if you wear corrective lenses, confirm with your optician that this protection is present.

Eye shields offer an alternative or supplement to standard sunglasses. These larger frames reduce UV entry from above and the sides, providing extra coverage that is especially useful for people who experience glare sensitivity.

Eye shields and glare-reduction options are available in multiple tints and colour filters, helping to sharpen contrast and visual clarity. Trying them in the environment where you plan to use them ensures you find the most suitable option.

Glare shields that clip over prescription glasses are another solution for those who wear lenses and struggle with bright light. Whether you need stylish sunglasses for a holiday or practical everyday eyewear, choosing a pair you are happy to wear regularly is key to consistent eye protection.

A full range of protective eyewear, including eyeshields and sunglasses, is available in the eyeshields and sunglasses section of the RNIB shop.
