Hello A dust particle will cause eye irritation,watering n redness Kindly consult local opthalmologist

If the dust particle is moving even after stoppage of eye movements that means it is floater means vitreous opacities moving here and there on eye movement. It is normal phenomenon but if it is happening with flashes of light then you must consult retinal surgeon urgently otherwise just relax.normal floater is not harmful.when it obstructs your vision then just move your eyes,it will move aside.

Hi.. what you are describing is a floater. I would advice you to consult your nearest ophthalmologist and get detailed evaluation done.

Hello...... You rinse you eye thoroughly.... Don't rub eyes repeatedly..... Ask for others help to remove particles... But foreign body sensation is common presentation in allergic conjuntavitis... If it's so avoid dust., pollution consult ophthalmologist in the nearest hospital........
