Eye problems such as blurry vision can drastically influence your quality of life. It’s difficult to perform daily tasks such as driving, reading or working at your computer when your vision is hazy and out of focus. On top of the fact that blurred vision can affect your daily life, it can also be a sign of other more serious health conditions or eye problems. BETTER VISION explains what the possible causes are, and what can be done to improve eyesight.
A black eye or periorbital hematoma is a bruise around the eye that is generally contained within the eye sockets.
Blunt force trauma around or close to the eye can cause capillaries to burst and lead to bleeding under the skin1. Because of the fatty tissues and lack of muscle surrounding the eyes, the blood tends to gather here, and the skin appears dark red, purple or black, and bruised. The appearance of bruises and soft tissue swelling is worsened by close proximity to the bone, and the fact that the skin around the eyes is quite thin.
Blunt force trauma (this is different from a penetrating injury) is usually caused by any type of blow to the eye. Other causes of black eyes include:
- Sinus infections, or an allergy or allergic reaction (from a bee sting to the nose or eyelid, for example).
- Facial surgery such as nasal surgery.
- Aesthetic treatments such as anti-wrinkle injections.
- Dental problems such as abscesses or tooth infections.
- Basal skull fractures can result in two black eyes called “raccoon eyes” or “panda eyes”, where blood from the fracture pools around the soft eye tissue. Seek medical attention if you suspect a skull or head injury .
Depending on how severe the injury is and your age, a black eye can disappear in about two weeks. Within a day or two following the injury, the swelling and discoloration will probably be at its worst, as the hemoglobin in the blood gathered around the eye breaks down. Following this, the swelling will gradually go down, and the bruise will fade from dark red or black to a yellow-green hue, before fading away completely.
It’s important to get a medical opinion if the discoloration and swelling takes particularly long to disappear, or it doesn’t show any signs of fading after two weeks.
Black eyes are often accompanied by broken blood vessels in the white part of the eye (subconjunctival hemorrhage). The eye will appear red and bloodshot, but although it may look painful and serious, you may not experience anything other than a little scratchiness on the eye surface.
Along with your bruise, the red patch will fade away over time and there’s no need to see a doctor if it’s not accompanied by a discharge, or if it doesn’t reappear concurrently.
- Ongoing pain experienced in the globe of the eye.
- If you have blurry vision or struggle to see with the injured eye, compared to the unaffected eye.
- A torn or cut eyelid that may require stitches.
- Eyes that can’t move together or in unison as usual.
- An unusual pupil size or shape compared to the other eye.
- When one or both eyes appear to be protruding from the sockets.
- Blood or accumulation of fluid in the clear part of the eye in front of the pupil (hyphemia). This is a serious condition, and if left untreated, can lead to increased eye pressure and possible vision loss due to glaucoma.
- A particle or object inside the eye that causes tearing and irritation and that can’t be removed.
There’s no special black eye treatment that exists. The only option is to wait it out and let your body and the tissue heal itself.
Initially, it’s best to place ice on the affected area. If it’s still painful after two days, try a warm compress but be careful not to make it too hot – it shouldn’t burn your skin. The heat may support the metabolic breakdown and speed up the healing process.
Get enough rest, drink plenty of fluids, and take care not to injure the area any further.
Black eyes and eye injury can be prevented in some cases. Your everyday glasses should be made from a shatterproof material, and if you are uncertain about the quality, consult your eyecare practitioner.
You should wear protective eyewear in the following instances:
- If you work in a profession where the risk of eye injury is big, such as construction.
- When you work on DIY projects at home that involve power tools or fast-moving objects.
- If you participate in sports such as tennis, it’s always advisable to wear protective sports eyewear.
- When you participate in any activity where there’s a risk of eye injury, opt to wear protective goggles or a helmet with a shield.
Unlike black eyes that are caused by some form of injury, bags under the eyes or puffy eyes is mostly a cosmetic concern. As already mentioned, the skin around and under the eyes is quite thin, and discoloration will appear more prominent in this area.
There are several reasons why you may have dark circles under your eyes. Skin tone and texture, and genetics certainly play a role.
The intensity of swelling and hue can also increase for the following reasons:
- Lack of sleep.
- When you have a sinus infection or are prone to allergies.
- Due to ageing skin.
- Increased levels of stress.
- When your fluid intake is too low.
- When you consume a lot of salty or processed foods, fluid retention is higher, and this may result in excess swelling around the eyes.
- Excessive use of alcohol.
- Apply lightening cream or eye cream daily, especially moisturizing products that contain vitamin E.
- Reduce sun exposure, and make sure your eyes and the area surrounding them are protected from harmful UV rays by wearing sunscreen or glasses that offer protection up to 400 nm.
- Drink plenty of fluids and follow a healthy diet that includes lots of fresh fruits and veggies.
- Get at least 7 hours of sleep every night.
- Elevation – sleep in a more upright position by adding an extra pillow to your bed at night.
- Massage the eyes to improve circulation.
- Place tea bags or cucumber slices on the eyes for at least 10 minutes, once or twice weekly.
- Treat yourself with a cooling eye gel mask from time to time to reduce swelling.
Dark circles can be associated with thyroid issues, anemia, allergies or vitamin deficiencies. If the discoloration appears suddenly and gets drastically worse over a short period of time, consult your medical practitioner.
