Of all the body parts, the eyes are among the most sensitive and cause the greatest concern whenever injured.

Many eye problems need same-day medical attention. Among them:- acute pain (not just scratchiness)

- blurred vision not helped by repeated blinking or putting on glasses

- chemical burn

- double vision

- seeing halos around objects (symptoms of glaucoma)

- sensitivity to light

- sudden loss of vision, with or without pain

- trauma (includes foreign body in eye)

Two of these conditions - chemical burn and painless loss of vision - call for immediate action.

Chemical burns

Gently irrigate the eye for 15-20 minutes with plain warm tap water or any noncaustic liquid available, even milk. Irrigating the eye during a shower or bath may be easier than trying to do so with running water from a faucet.

Tell the victim to turn his or her head toward the side of the injured eye so that the irrigating liquid runs from the nasal area to the outer side. This prevents contamination of the other eye.

As soon as possible, determine what chemical entered the eye.

Seek medical attention immediately.

It is not necessary to neutralize an acid with a base or a base with an acid. Alkali burns are more dangerous than acid burns because alkali can easily penetrate the eye and damages for a longer time period. Acid burns differ from alkali burns since long-term damage won't be produced as it is in an alkali burn.

Foreign body

If the irritation can't be identified, gently irrigate the eye with warm water. The first aid giver may have to help hold the eye open during the irrigation process. If this does not flush out a foreign body, seek medical attention for the victim.

For penetrating objects stuck in the eye, do not remove the object and immediately call an opthalmologist.
