I am suffering from a dry eye and my doctor have given me just a drops (lacryl ultra) and he have suggested me spectacles with power 0.5 which I use when I drive do works and use the phone. But still at certain instants my eye do feels strained and headaches and I have used I tone in that case and I felt better. And I wanted to even know if dry eye can be completely cured and in future can I use contact lenses instead of spectacles which have given now.
