Hello,
Your consult was initially seen by Dr.Vivek Verma ( Immunology and Allergy specialist ) and forwarded to me.
The scratchy n dryness of the eye that you feel is more allergic in nature , this can be because of the change of season or because of some allergy (dust,pollen etc).
You can wash your eyes with mild cold water at least 3-4 times a day. Take an OTC anti allergic medication like Cetirizine or Allegra once a day. If the symptoms persist, you may have to visit your GP/ Ophthalmologist.
Hope this helps
Please feel free to ask followup questions.
Thank you
