Expatriate healthcare insurance policyholders who live in countries with a hot climate may want to follow the advice of one expert and ensure they wear suitable eyewear when out in the sun.
Ambassador for Rohto Dry Eye Relief Nick Atkins explained good quality sunglasses are "essential" when spending any length of time in bright sunlight.
He said eyewear with a rating of UV400 can help reduce the risk of developing cataracts and other long-term problems.
Graham Cox of Ultralase recently advised individuals to undergo regular cataract checks, as the condition can affect everyone.
They can result in blindness if left untreated and trauma, diabetes and some medicines – such as steroids – all have the potential to increase the onset of cataracts.
Mr Atkins also suggested using eyedrops to relieve irritability caused during the summer months, as "air conditioning on planes [and] trains", in addition to arid climates", can improve comfort.
