Hi Wear glasses Reduce too much screen time . Use some lubricating drops Maintain healthy lifestyle Take crocin for couple of days for headache.

I guess you did not wear Spectacles in early childhood. Right eye must be having what we call Anisometropic Amblyopia. But nothing to worry about as you won't find any trouble with any functions you do in daily routine and also in most jobs other than jobs like Armed forces. Please use your Spectacles regularly and follow all the exercises your Ophthalmologist has suggested and maintain a regular follow up. Continue with the same treatment.
