Be seen today
Seek prompt medical advice for persistent gritty, red, watery, or uncomfortable eyes, especially if symptoms keep returning.

Eye pain or marked light sensitivity
New or worsening blurred vision
A very red eye with significant discomfort
Difficulty keeping the eye open

Does any of this apply?
Book an appointment
Arrange a routine appointment if you develop ongoing central facial redness, repeated flushing, unexplained facial bumps, visible blood vessels, or skin thickening.
Assessment is also appropriate if presumed acne treatment is not helping or makes your face sting and flush.
Every sign above is quoted from the sofidex article on Rosacea. If you are not sure, err upward — it is always reasonable to be checked.
