Frequent headaches? Your eyes may be the reason

Recurring headaches are not always caused by stress or neurological problems and may signal the need for an eye check-up, says Dr Vivek Garg, ophthalmology head at BLK-Max Super Speciality Hospital. He says he often sees patients who spent months or even years on painkillers, brain scans and neurologist visits before discovering their headaches were linked to their eyes.
