Eye Injuries Foreign Body In The Eye

Overview

A foreign body in the eye means something that does not belong there has got into your eye or under your eyelid. It might be a speck of dust, a grain of sand, an eyelash, a bit of grit, a flake of makeup, a tiny piece of metal or wood, or a splash of a chemical. Most of the time it sits on the surface of the eye or under the eyelid and can be gently washed or blinked out. Sometimes it can scratch the clear front surface of the eye, called the cornea, or get stuck in it. A foreign body can be uncomfortable and worrying, but most small ones settle quickly once they are removed.

Yes, it is very common. Eye injuries from small objects are one of the most frequent reasons people go to an eye doctor or emergency department. Most are minor and heal well.

Anyone can get something in their eye. It is more likely if you work with your hands, do DIY, use tools like drills or grinders, spend time in dusty or windy places, wear contact lenses, or have dry eyes. Children often get sand, dust or small toys in their eyes while playing.

Symptoms

Common symptoms

• A gritty, scratchy or sandy feeling in the eye
• Watering and a lot of tears
• Redness and soreness
• Being sensitive to light
• Blurred or slightly hazy vision
• Feeling like something is still there even after it has gone
• Finding it hard to keep the eye open
• A small visible speck on the white of the eye or under the eyelid

Symptoms in children

• Rubbing the eye a lot or holding it shut
• Crying and being clingy or irritable
• Refusing to open the eye
• Red, watery eye
• Not being able to say what happened, especially in toddlers

Symptoms in older adults

• Dry eyes can make a gritty feeling last longer
• Symptoms may be milder or noticed later, especially if eyes are less sensitive
• People with previous eye surgery, such as cataract surgery, should get checked sooner
• Confusion or memory problems may mean the eye problem is noticed late

Causes

Main causes

• Dust, sand, grit or soil blown into the eye
• Eyelashes or flakes of skin
• Makeup, such as mascara flakes or eyeliner
• Small pieces of metal from grinding, drilling or hammering
• Wood chips, glass fragments or plastic bits
• Chemical splashes from household cleaners or workplace products
• Contact lenses that are torn, trapped or have something stuck behind them
• Insects or small plant material, such as grass or seeds

Risk factors

• Not wearing eye protection at work or during DIY
• Working in dusty, windy or outdoor environments
• Using power tools or welding equipment
• Wearing contact lenses, especially if you swim or sleep in them
• Dry eyes, which can make the surface more easily irritated
• Children playing in sandpits or with small toys
• Previous eye surgery or eye conditions

When to see a doctor

See a doctor urgently if:

• Something is stuck in or on the eye and gentle rinsing has not shifted it
• A chemical has got into the eye — flush first, then get help straight away
• You have eye pain, redness or light sensitivity that is getting worse
• Your vision has changed or become blurry
• An injury happened while using tools or machinery
• You wear contact lenses and think something is trapped under the lens
• A child has a red, painful eye or will not open it

Book a routine appointment if:

• The eye feels better but still gritty after a day or two
• You keep getting things in your eye and want advice on prevention
• You have a small, painless spot on the eye that has been there a while
• You want your eyes checked before starting a job that involves tools or dust

Diagnosis

A doctor or optometrist will ask what happened, when it happened, and whether you were using tools or chemicals. They will check how well you can see, look closely at your eye and eyelid with a bright light and magnifier, and may turn your upper eyelid over to look underneath. If needed, they use special eye drops that make small scratches on the surface of the eye show up under a blue light. This is quick and usually not painful.

Tests that may be done

• Vision test — reading letters or shapes to check how clearly you see
• Slit lamp examination — looking at the eye through a special microscope with a bright light
• Fluorescein drops — a dye that highlights scratches or damage on the eye surface
• Eyelid eversion — gently flipping the upper eyelid to look for hidden objects
• Imaging, such as an X-ray or scan, only if a metal or deep object is suspected

What to expect at your appointment

The check-up is usually quick and done in a clinic or emergency department. You may be given numbing drops so the eye can be examined comfortably, and dye drops that temporarily make your vision slightly blurry and your tears glow yellow. You should be able to go home the same day in most cases. Sometimes you will be asked to come back for a follow-up to make sure the eye is healing.

Treatment

The main treatment is simply to remove the object safely and let the eye heal. Many small objects come out with blinking or gentle rinsing at home. If something is stuck, a doctor can remove it with special equipment and magnification. Most people feel much better within a day or two, and the eye surface usually heals quickly on its own.

Self-care at home

• Do not rub the eye. This is the most important thing you can do.
• Blink rapidly several times to encourage tears to wash the object towards the inner corner of the eye.
• Try rinsing with clean, cool water or sterile saline — use an eye bath or a clean cup, or rinse under gentle running water.
• If the object is on the white of the eye or the lower lid, you may be able to lift it gently with the corner of a clean tissue or a damp cotton bud. Never touch the coloured part of the eye.
• Do not use tweezers, matchsticks, cotton buds on the coloured part of the eye, or any sharp object.
• Avoid wearing contact lenses until the eye feels completely normal, and throw away the lens that was in the eye when it happened.
• Give your eyes a rest from screens if they feel sore, and avoid smoky or dusty places for a day or two.

Medical treatments

In a clinic, the doctor may first wash the eye with saline to flush out loose material. Loose objects can often be lifted off with a moistened swab. Objects stuck to the surface may be removed using a fine instrument under a microscope, after numbing drops so it is not painful. If the eye surface has been scratched, you may be given lubricating drops and, in some cases, antibiotic eye drops or ointment to lower the risk of infection. A soft pad or shield may sometimes be placed over the eye for a short time. You may be asked to come back for a check-up. Always follow the instructions you are given and ask your pharmacist or doctor if you are unsure how to use any drops.

When is surgery considered?

Surgery is needed only in a small number of cases. It may be considered if an object is deeply embedded in the eye, if there is a piece of metal that has left a rust ring on the eye surface, or if the eye has been seriously injured. These procedures are carried out by an eye specialist, usually in a hospital.

Living with this condition

For the first day or two, your eye may feel gritty and look a little red, even after the object is gone. This usually settles. Try not to touch or rub the eye, keep your hands clean, and avoid eye makeup and contact lenses until it feels normal again. If you are given drops, use them as instructed and finish the course if you have been told to.

Lifestyle tips

• Wear safety glasses or goggles for DIY, gardening, and any job that creates dust or flying bits
• Keep your hands clean and wash them before touching your eyes
• Follow the care advice for your contact lenses and never sleep or swim in them
• Use lubricating drops if your eyes are often dry, as this helps small specks wash away more easily
• Keep a small eye-wash kit or sterile saline at home and in the car if you work with dust or chemicals

Diet and exercise

There is no special diet for an eye injury. Eating a balanced diet with plenty of fruit and vegetables supports general eye health. You can carry on with normal activity, but take care not to get dust, sweat or dirt in the eye while it is healing, and avoid swimming for a few days if the eye has been scratched.

Mental health and emotional wellbeing

Eye injuries can be frightening, especially if your sight is briefly blurred or if the injury happened at work. Most people feel anxious until they know the eye is healing. This worry usually fades within a few days. If you find that fear about your eyes or your sight is affecting your sleep, mood or daily life, please talk to your doctor. If you ever have thoughts of harming yourself, contact your local emergency number or a crisis support service straight away — you deserve help and you are not alone.

Prevention

Many eye injuries can be prevented. Wearing proper eye protection is the single most effective step. Choose goggles or safety glasses that fit well and are suitable for the task. Store chemicals safely, keep the caps on, and never mix household cleaners. Handle contact lenses carefully, keep them clean, and follow the wearing schedule your optician gave you.

Screening programmes

There is no routine screening test for this. It is still worth having regular eye tests, usually every two years, as these can pick up eye problems early and keep your eyes healthy.

Complications

If left untreated

• A scratch on the clear front of the eye, which can become infected and form an ulcer
• A long-lasting gritty feeling or pain if an object stays under the eyelid
• Scarring of the eye surface, which can affect vision
• A rust ring left by a small metal fragment
• Rarely, serious damage to the eye from chemicals or deep objects, which can threaten sight

Long-term outlook

The outlook is good for most people. Small objects that come out quickly usually cause nothing more than a day or two of grittiness, and the eye heals itself well. Even a scratched eye often heals within a few days with simple care. Getting help early if something is stuck, or if a chemical is involved, gives the best chance of protecting your sight. If you are ever unsure, it is always fine to ask for a check-up.
