Common Eye Problems

Common eye problems can affect people of all ages, and can stem from environmental factors, increased use of technology or physical changes due to ageing and medication.

Eye Fatigue & Computer Vision

Symptoms of eye fatigue and discomfort have become commonplace with the rapid increase in computer use and introduction of mobile devices, and can be caused by any activity which requires our eyes to focus for intense periods such as reading or driving.

SYMPTOMS CAN INCLUDE:
Headaches towards the front of the head, dry and irritated eyes (due to lack of blinking), eyestrain, blurred vision, slow refocusing, sensitivity to light, and double vision.

MANAGING EYE FATIGUE
The good news is that you can greatly reduce eye fatigue symptoms by creating a more eye-friendly work environment:

  • Position your monitor squarely in front of you, approximately 40-45cm away
  • When reading a source document, position it right next to the monitor to reduce eye movement and focusing changes
  • Lighting should be arranged to minimise reflections and glare
  • Take periodic visual breaks, at least every 30-60 minutes

COMPUTER VISION GLASSES
In addition to rearranging your computer workstation, speak with your optometrist about appropriate computer vision glasses that are designed to give you optimal close-up and intermediate vision as well as reduce eye fatigue, neck and shoulder discomfort and blue light emittance.

Dry Eye

Tears provide our eyes with natural nourishment and protection against irritants such as dust and smoke, and keep our eyes lubricated. Dry Eye occurs when the tear film is not produced in sufficient quantity or evaporates from the eyes too quickly. In both instances, unprotected areas on the surface of the eye result in dry spots.

SYMPTOMS CAN INCLUDE:
A dry or gritty sensation, sore or tired eyes, watery eyes, blurred vision, sensitivity to light, burning, irritated eyes or red eyes.

CAUSES OF DRY EYE

  • Aging, as tear production naturally reduces
  • Reduced blinking when concentrating on technological devices
  • Hormonal changes, contraceptive pills and other medications such as anti-histamines, diuretics and anti-anxiety pills
  • Environmental factors such as dry windy weather, direct sunlight, smog or dust, air conditioning/heating, and cigarette smoke

TREATING DRY EYE
Mild Dry Eye is best managed using tear supplements. More serious cases of Dry Eye caused by reduced tear production may require the blockage of tear ducts with punctual plugs to keep the tears in the eye longer.

Eye Allergies

Seasonal allergies are a common frustration for many Australians who suffer from red, itchy or watery eyes.

SYMPTOMS CAN INCLUDE:
Swelling or puffiness of the eyes, redness, itching, drying, tearing discharge from the eye and discomfort when wearing contact lenses.

If you experience any of these symptoms for an extended period of time, contact your local ProVision Optometrist to have your eyes thoroughly examined.

HAY FEVER TIPS FOR CONTACT LENS WEARERS

  • In peak hay fever season, swap contact lenses for glasses
  • Avoid wearing contact lenses when outside conditions are hot, dry and dusty
  • Wearing sunglasses as well as contact lenses can add an extra level of protection from dust and pollen circulating in the air
  • Avoid wearing contacts when mowing the lawn or gardening
  • Remove your lenses out immediately if your eyes become sore and red  
  • Take advantage of daily disposable contact lenses – replacing them daily reduces the chances of protein build up which leads to sore, irritated eyes
