Pls suggest some eye drop for dryness?

Multiple: see your practitioner. Some things that may help are:increasing your health dietary fats, adding omega 3 supplements 3-4000 mg per day, drinking half your body weight in ounces, and OTC lubricating drop.

Dryeyes: Usually lubricating eye drops such as refresh or Systane will work. There are also many others. Should use about 4 times a day, mainly on awakening and bedtime. If no relief see your ophthalmologist for further treatment.
