Is there any discharge present in the eyes?
yes a lot
If the discharge is purulent then it should be bacterial conjunctivitis which you would have caught while cleaning from some infected source. Dust can cause allergic conjunctivitis in which the redness is there but the discharge is clear and watery. For bacterial conjunctivitis you can use an anti-biotic drop like Gatifloxacin or Moxifloxacin. The eye should be alright in 2-3 days. You can see an ophthalmologist for confirmation. Thanks and best wishes.
Follow-up questions, if any, are welcome.
In conjunctivitis foreign body sensation is common and so you feel as if something is there in the eye. As it resolves this sensation will go. Thanks.
