We demand a lot from our eyes and, when they become tired, sore or bloodshot, we tend to put it down to the stresses and strains of everyday life. But these symptoms could also indicate a more serious problem, which is why it’s vital to have regular check-ups. Read on for our focus on eye health.
What to look for
Eyes are amazingly resilient and generally quick to heal from minor injuries, infections, abrasions and other irritations. But it’s really important to have a full eye check every two years – which is covered by Medicare – or annually, if you’re over 50, to spot problems before they become too serious. And as well as regular check-ups, if your eyes begin to bother you or your vision suddenly changes, don’t delay seeking help. Here are a few problems to look for.Symptom: Dry, sore, tired eyes.
It could be: Lack of sleep, air-conditioned or smoky environments, or eye strain. If you work on a computer, take regular breaks from the screen and get some fresh air. Eye drops may help, but consult your pharmacist or GP to make sure there’s no underlying condition.
Symptom: Scratchy, gritty or itchy eyes.
It could be: Lack of lubrication can cause eyes to feel dry and scratchy. This could be caused by medications, hormonal changes, recovery from eye surgery, seasonal allergies or reactions to products such as make-up, cleansers or detergents. If problems persist, see your doctor.
Symptom: Red, swollen eye rims, crusty build-up on lids, itching, burning.
It could be: Blepharitis (eyelid inflammation), a bacterial infection, seborrhoeic dermatitis or allergies. See your GP as soon as problems occur to determine the best course of action.
Symptom: Pimple-like sores on eyelids.
It could be: A sty, generally caused by bacteria, a blocked pore or oil gland. It usually resolves itself, but may need antibiotic drops. Whatever you do, don’t try to pop it!
Symptom: Bloodshot, gunky, weeping eyes.
It could be: Conjunctivitis (pinkeye) – a contagious condition caused by a viral or bacterial infection, which may require antibiotic treatment by your doctor.
Symptom: Sudden flashes of light or floaters (tiny spots that seem to swim in front of you), or a sense that a shadow is falling across your eye from the top or side.
It could be: Warning signs of a detached retina, a serious condition that needs immediate attention as it can lead to vision loss and blindness. It can happen as a result of eye trauma but, often, it occurs for no known reason. It’s not painful, so heed the symptoms – it’s better to be overcautious than risk your sight.
EAT THIS!
Once upon a time, it was all about carrots, but the latest research shows that foods
rich in antioxidants, omega-3 fatty acids and other essential vitamins and minerals also play an important role in keeping eyes healthy. Munch on leafy greens such as spinach, kale and broccoli, Brazil nuts, oysters, salmon, avocados, garlic, tomatoes, blueberries, egg yolks, wholegrains and sunflower seeds.
Tips for better eye health
Follow this advice to help keep your eyes in top shape:- Get enough sleep.
- Drink plenty of water.
- Maintain a healthy diet.
- Keep your weight within a healthy range.
- Get regular exercise.
- Avoid transferring bacteria to your eyes by washing your hands frequently.
- Don’t smoke.
- Never share make-up tools or products as they can harbour bacteria.
- Replace your eye make-up every four to six months. If you get an eye infection, such as conjunctivitis, toss eye make-up immediately.
- Remove eye make-up before going to bed.
- Wear good-quality sunglasses with an eye protection factor of 10, all year round.
- Wear eye protection if working or playing sport in an environment that could pose a threat to your eyes.
- Exercise your eye muscles by switching focus every so often. Look away from your screen or other close work and out into the distance. Scrunch your eyes tightly for a few seconds, then open wide, look up, down, and from side to side.
- If you have contact lenses, use, clean and dispose of them as directed.
- Get regular check-ups by an eye-care professional.
These serious eye conditions require immediate attention.
Macular degeneration (MD)MD is the leading cause of blindness in Australia. The macula is the central part of the retina – the part of the eye that processes visual images. Symptoms include difficulties focusing and seeing at night, empty spaces in your central vision and light sensitivity.
Most at risk: People over 50, smokers and those with a family history of MD. Prevention: Have yearly eye check-ups after 50, and request your optometrist examine your macula. If you’re a smoker, stop.
Glaucoma
This is a disease in which the optic nerve is slowly destroyed, usually due to a build-up of pressure in the eye. It has no initial obvious symptoms and leads to irreversible blindness.
Most at risk: Those with a family history of glaucoma, or if you have high blood pressure, short- or long-sightedness, diabetes, migraines, an eye injury or overuse steroid medications.
Prevention: If you’re over 35, and at risk, have annual eye checks. Early treatment can prevent vision loss.
Diabetic retinopathy
Diabetics are at risk of this condition, in which blood vessels inside the retina are damaged, leading to vision problems and blindness.
Most at risk: Long-time diabetics, and those with poorly managed diabetes who also have high blood pressure or kidney disease.
Prevention: Keep blood glucose levels in the normal range, eat a healthy diet, take prescribed medications as directed, don’t smoke and have regular eye check-ups.
Cataracts
Affecting one or both eyes, cataracts can cause blurred and distorted vision, light sensitivity, double vision and distortion. They can be treated with surgery.
Most at risk: Those with a family history, diabetics, smokers, anyone who has had long-term, unprotected exposure to strong sunlight.
Prevention: Stop smoking, wear sunglasses, manage diabetes, have eye check-ups
