Final answer:
The recommended action for corneal staining in contact lens wearers is to reduce wear time, use rewetting drops, and refit the contact with lower wetting content.
Step-by-step explanation:
Corneal staining is a common issue that can occur in contact lens wearers. The recommended action for this condition is all of the above, which includes reducing wear time, using rewetting drops, and refitting the contact with lower wetting content. By reducing wear time, the cornea is given time to recover and can prevent further staining. Using rewetting drops can help to keep the contact lens moisturized, reducing the risk of staining. Finally, refitting the contact lens with lower wetting content can also help improve the condition.
