Expatriates with overseas health insurance may wish to consider having their eyes checked for cataracts and have them dealt with early if they occur.
This is according to Graham Cox, professional services manager for vision correction specialist Ultralase, who said this condition "eventually affects everyone".
It can be caused by surgery for other eye conditions, as well as trauma, diabetes and medicines, particularly steroids, the Royal National Institute of Blind People stated.
"Replacing the cloudly lens with an artificial one" is the best way to treat the problem, Mr Cox added, noting that drugs, glasses or other non-surgical interventions have no effect.
Cataracts can cause blindness if left alone and are currently the leading global cause of impaired vision, the expert declared.
He compared seeing through such eyes to looking out of a frosted window or one that has become obscured with steam.
This problem can affect individuals under the age of 40 and although those who suffer from the condition are generally over 65, people younger than this are not checked often enough, Mr Cox said.
