International healthcare policyholders may wish to wear sunglasses all year round after an expert claimed these provide valuable protection.
Eyecare Trust chairman Dharmesh Patel asserted that the "cumulative damage caused by unprotected exposure to ultraviolet radiation (UV) can increase your risk of suffering sight-threatening conditions".
These ailments include cataracts and age-related macular degeneration, he continued.
Furthermore, individuals with allergic rhinitis and hay fever can minimise their symptoms through wearing sunglasses, as these prevent pollen and other airborne irritants from reaching their eyes, the expert pointed out.
Mr Patel noted that the Eyecare Trust recommends wearing these devices whenever the UV Index reaches higher than three, which can even happen on cloudy days.
Sunglasses give members of the public "valuable protection" throughout the year and "not just in the hot summer months", he added.
Smoking can also damage people's vision, the charity argued, noting that 90 per cent of tobacco users are unaware of this risk.
