People may be abele to cut their likelihood of paying for vision treatments on international health insurance policies by paying attention to their general health.
Medical director of Harley Street vision correction clinic Advanced Vision Care CT Pillai suggested that members of the public should wear sunglasses when it is bright, exercise regularly, abstain from tobacco and eat properly, as these are "all important for healthy eyes".
However, the "single most important thing" is to have an eye exam every 24 months, or every year for individuals who wear contact lenses or glasses, he added.
Ocular tests can also indicate whether or not a person suffers from a range of other conditions, including retinal diabetes, glaucoma and macular degeneration, the specialist declared.
International healthcare research has found people of South Asian heritage are more likely to suffer from glaucoma than those of other ethnicities.
Rarely, problems with sight can indicate that a person has a brain tumour or other serious conditions, Mr Pillai said.
