Encourage increased fluid intake to reduce ocular dryness and irritation.

Apply warm compresses to the eyes to enhance circulation and reduce inflammation.

Elevate the head of the bed to reduce periorbital edema and promote comfort during sleep.

Administer atropine eye drops to dilate the pupils and relieve pressure.
