Frequently asked questions

When is eye pain an emergency?

Severe eye pain, especially with reduced vision, nausea, halos around lights, or after an injury or chemical splash, needs immediate care.

Why does my eye hurt but look normal?

Dry eye, eye strain and early surface problems can cause discomfort with little to see. Persistent or severe pain should still be assessed.

What is the difference between sore and painful eyes?

Mild soreness is often from dryness, strain or blepharitis, while significant pain, especially with vision changes, points to causes that need prompt attention.
