First Aid Tips to Treat Eyes Injuries

First Aid Tips to Treat Eyes Injuries

The eye is a special body organ made up of different components that work together to provide vision. The eye has a outer layer called the white layer or sclera. The white layer is relatively tough for protection. The sclera is covered by another thin transparent membrane known as conjunctiva. The membrane also covers the moist part of the eye lids and eyeball.

The cornea is the clear layer covering the pupil and iris, and it allows light into the eye. The cornea also protects the eye while at the same time focusing light at the back of the eye (retina). The pupil is the black spot in the middle of the eye through which light travels into the eye. The iris surrounds the pupil and it controls the amount of light that goes through the eye. It does so by adjusting the size of the eye. In bright environment, the pupil iris contracts/constricts to limit the light entering the eye. In dark environment the iris will expand to allow more light into the pupil. These functions are performed by the dilator and sphincter muscle of the eye.

The lens of the eye is behind the iris and its functions are focusing light into the retina. The lens works by focusing on objects at different distances. For nearby objects, the lens thickens. When focusing on distant objects, the lens gets thinner. The thickness of the lens is controlled by ciliary muscles.

The retina, located at the back of the eye contains photoreceptor cells that sense light, and blood vessels that supply them with blood. The macula is the most sensitive part of the retina. It contains closely packed photoreceptor cells (cones). Cones make the image more detailed by providing a high resolution. Each photoreceptor cell is connected to a nerve which when combined form the optic nerve. Photoreceptor cells convert images into electrical signals that are transmitted to the brain by the optic nerve. There are two types of photoreceptor cells: cones and rods. Cones provide colored, detailed, central and sharply focused images while rods are useful in peripheral and night vision.

The eyeball has two fluid filled sections namely the anterior and posterior segments. The fluid contained in the eyeball gives it it’s shape. The eye has a set of protective features with help in the prevention of injuries.

The Orbit

The eye is contained in a bony structure that goes beyond the surface of the eye. This bony structure (orbit) protects the eye while allowing free movement.

The Eye Lashes

These are short hairs growing on the upper and lower edges of the eyelid. The hair protects the eye from the entry of foreign particles such as dirt and insects.

The Eyelids

These are thin covers of the eye made of skin and muscle. They eyelids blink at the slightest sensation to protect foreign objects from entering the eye.

The Conjunctiva

The moist covering membrane of the eye covers the eye while protecting the sensitive tissues beneath. It covers the eyelids and eyeball.

Tears

Tears are made of salty fluid that bathes the eye while nourishing the  cornea which lacks blood vessels. The components of tears include water, oil and mucus. Tears ensure that the eye is moist and sweeps away dust and dirt particles that accidentally enter the eye. Blinking helps in transferring moisture to the outer parts of the eye. An oily substance produced at the eyelids keeps the tears from drying. Tears also contain antibodies that protect the eye from infections. When the cornea dries up, it becomes infected, opaque and injured.

Eye Injuries and First Aid

Eye injuries can result from industrial or domestic accidents. The eye is a sensitive organ and any injury to the eye should be treated as an emergency to protect vision and prevent complications. There are different types of injuries: chemical, foreign object, blow to the eye and puncture or cuts.

Chemical Injuries

Chemicals accidentally flash into our eyes, and are very painful. The most dangerous chemical burns occur from strong alkalis and strong acids. We should always wear safety glasses when handling abrasive substances and chemicals to protect our eyes from these injuries. Some substances likely to cause injuries include fertilizers, detergents, drain cleaners, motor, plaster, concrete and lime products. Chemical burns on the cornea of the eye can result in scarring, infection, perforation and blindness.

When chemicals splash into our eyes, we should remain as calm as possible and try to keep the eyes open. Closing the eyes spreads and traps the chemicals inside. Flash the eyes with a lot of water for 20minutes. The eyes should remain open as you do so.  Immediately seek specialized treatment. You should call the poisons control centers to provide further assistance and explain the type of chemical.

Foreign Object in the Eye

In most cases the eye cleans out dirt and other small particles. When an object enters your eye, you should avoid rubbing which results in further damage. Lift the upper eyelid and place it over the lower one, then try to roll your eye round. With your eye open flush the eyes with a lot of water. Repeat the procedure until the object comes out. Have a doctor check your eyes for any damage or remaining particles. The eye doctor will use specialized light to assess any injuries and provide the necessary treatment.

Do not attempt to remove an objects that is stuck in the eye. Cover the eye with a gauze or shield and rush to the hospital.

Blow to the Eye

Blows to the eye might be minor or major depending on the extent of damage. Minor injuries can heal on their own, however you should monitor the injury for complications such as infection. If you suffer a blow to the eye, gently apply a cold compression on the eye for five to ten minutes. Allow the same amount of time then apply gain. Do not apply the directly on the skin. You can wrap the ice in a piece of cloth then apply on the injured eye. Call the doctor for assessment. It is important to establish the extent of the injury and get the necessary medication. After 24hours use a warm compression on the eye to reduce the bruising. See a doctor if you notice any signs of infection. The following are symptoms of eye infection:

  • Drainage from the eye
  • Persistent pain
  • Bleeding
  • Change in vision
  • Any visible change or abnormalities in the eye
Cuts or Puncture on the Eye

Most eye injuries occur on the eye lid due to the reflex action of the eye to close to avoid injuries. SeekSeek immediate medical care if you suffer a cut or puncture to your eye. As part of first aid:

  • Do not attempt to clean or wash the eye
  • Do not attempt to remove any object stuck in the eye
  • Wear an eye shoes or improvise one (to improvise, split a paper cup and tape the bottom part over the injured eye).
Thermal Burns

Burns to the eye are treated as normal burns. Burns on the eyes are medical emergencies. Immediately call for emergency medical services. Remove the source of heat and move the victim to safety. Run cold water over the burn. Do not run water over major burns, instead seek immediate treatment from a doctor. Do not break any blisters as it leads to loss of water from the victims body and also infections. Place a clean bandage over the burn and seek specialized treatment.

The eye is a sensitive body organ. Injuries to the eye can lead to complications and blindness. To protect your eyes from damage and injuries:

  • Avoid looking directly at the sun especially during an eclipse.
  • Take note of instructions before using machines or playing games.
  • Wear sunglasses that protect your eyes from UVA and UVB rays from the sun when going outside.
  • Wear protective goggles and glasses during sporting activities and when using fireworks.

  • Clean your hands thoroughly after touching chemicals.
  • Be cautious when opening wine bottles and carbonated drinks.
  • Always wear eye protection when using weed trimmer and lawn mower.

Summary:

Eye care is important as loss of vision can be traumatizing and life changing. To ensure good eye health, we need to eat a well balanced diet with plenty of fruits and vegetables. We should also avoid disease that affect our eye sight such as diabetes and hypertension by maintaining a healthy body weight. We can do so by regular physical exercise and avoiding smoking. Everyone should see an eye doctor and have their eyes examined at least once a year. People with family history of illnesses such as diabetes should get regular tests. If you are diagnosed with eye problems always follow the doctor’s recommendation of treatment. Persons wear prescription glasses should always follow the doctor’s instructions.
