It's important to get regular eye exams, but some symptoms may call
for immediate attention. Seek emergency treatment if you experience the
following symptoms in one or both eyes: pain; hazy, blurred or double
vision; sudden vision loss; a curtain-like appearance over your field of
vision; an increase in the number or size of floaters; flashes or
streaks of light; sudden appearance of rainbows or halos around lights;
loss of peripheral vision; or swelling or redness of eye or eyelid.
These could indicate a retinal detachment or other serious eye
