What counts as an eye emergency?

Not every red eye or eye pain is an emergency, but several specific symptoms always warrant immediate attention. Treat any of the following as urgent — call us during business hours or head to the ER after hours:

  • Sudden vision loss: Partial or complete loss of vision in one or both eyes, including a "curtain" or shadow over part of your vision. Can signal retinal detachment, vascular issues, or even stroke.
  • Eye injury or trauma: Blunt force, penetrating injuries, deep cuts to the eyelid or eye, embedded foreign objects, or chemical splashes.
  • Severe eye pain or persistent redness: Sharp pain with light sensitivity, redness that doesn't resolve, or pain accompanied by vision changes. Can indicate infection, uveitis, corneal ulcer, or acute glaucoma.
  • New flashes of light or sudden shower of floaters: Especially with a shadow or curtain in peripheral vision. Possible retinal tear or detachment — every hour matters for preserving vision.
  • Sudden double vision: Particularly with headache, weakness, confusion, or any other neurological symptoms.
  • Foreign body sensation that won't resolve: Especially after metalwork, woodworking, sanding, or gardening — if rinsing doesn't flush it within a few minutes, you likely need professional removal.

What to do before you arrive — by emergency type

The right first response often makes a significant difference in outcomes:

Chemical splash: Rinse continuously with clean lukewarm water or saline for at least 15 minutes. Don't stop to call. Strong acids and alkalis (drain cleaner, bleach, oven cleaner) are true emergencies — keep rinsing the whole drive.

Foreign object: Don't rub. Don't try to remove anything embedded. If it's loose debris, blink gently to let tears flush it. If it doesn't come out within a few minutes, call us.

Blow to the eye: Apply a cold compress (not pressure) for 15 minutes. Watch for vision changes, blood pooling in the eye, severe pain, or a pupil that looks irregular.

Sudden flashes or floaters: Don't wait. Call us immediately during business hours, or head to the ER if after hours.

Severe pain or red eye: Don't use leftover eye drops. Don't rub. Call us for same-day evaluation.

Optometrist vs ER — where to go

For most non-traumatic eye emergencies, an optometrist is the better first call. We have the slit lamp, magnification, and corneal-specific tools the ER usually doesn't, and a visit costs significantly less than an ER bill. Most foreign-body removals, infections, abrasions, sudden vision changes, and acute eye pain are handled faster at an optometrist than at a hospital.

Go to the ER first if:

  • You have a penetrating eye injury or deep cut
  • An object is embedded deep in the eye (don't try to remove it)
  • You've had head trauma alongside eye symptoms
  • You've had a major chemical burn (strong acid or alkali)
  • You have stroke-like symptoms alongside vision changes
  • It's outside our business hours and the situation can't wait

For more detailed guidance on this distinction, see our full Emergency Eye Care page with side-by-side triage tables.

Why early intervention matters

The eye is a delicate organ with limited capacity to heal once damaged. Several conditions can progress within hours from "treatable" to "permanent vision loss":

  • A retinal tear can progress to a full retinal detachment in hours to days
  • A corneal infection can scar the cornea permanently if untreated
  • Acute angle-closure glaucoma can damage the optic nerve irreversibly within hours
  • An embedded metal foreign body left in place can rust and stain the cornea within 24 hours

When in doubt — call. We'd much rather see you for nothing than miss something that mattered.

If you're not sure — call first

If symptoms don't clearly fit any category above but feel "off," call us. Phone triage takes 2 minutes and we can usually tell you whether you need to be seen, can wait, or need to head straight to the ER. There's no charge for the call, and there's no judgment for being cautious about your eyes.

During business hours, same-day appointments for urgent issues are usually available. After hours, our voicemail directs you to the nearest emergency department for severe symptoms.
