Eye Conditions

  


Prescription Based Conditions

Myopia (Short-sightedness)

A condition where distance objects appear out of focus and near objects are usually seen clearly. The main symptom is blurred distance vision.

Hyperopia (Long-sightedness)

A condition where extra effort is required to focus at near. This can result in eye strain, fatigue, headaches, blurred near vision, avoidance of nearwork and/or short attention span for near tasks.

Astigmatism

A common condition where the eye is shaped more like a grape, rather than a marble, causing distortion or blurring of distance and/or near objects.

Presbyopia

An ageing condition where it becomes increasingly more difficult to see clearly up close. After the age of 40 the crystalline lens within your eye hardens making it more difficult to focus. This can result in eye strain, blurred near vision, difficulty reading in dim light and the need to extend your arms to maintain clear near vision.



Other

Amblyopia (Lazy eye)

A condition where the vision in one eye (and occasionally both) does not develop fully during childhood due to poor visual input as a result of uncorrected high prescription, eye turn, cataracts or eyelid droop. This condition is best treated as early as possible.

Computer Vision Syndrome

A group of vision-related problems caused by prolonged computer use, including eyestrain, headaches, blurred vision, dry eyes and/or neck pain. These symptoms may be a result of poor lighting, incorrect working distance or posture, computer screen glare and/or uncorrected prescription. Your optometrist can recommend treatment options.

Colour Vision Deficiencies

A condition wear there is an altered perception of colour. This is most commonly an inherited condition affecting approximately 8% of males and 0.5% of females.


Medical Based Conditions

Dry Eyes

A common condition where there is a decrease in tears on the front surface of the cornea due to poor tear production or increased tear evaporation. Dry eyes can cause irritation, gritty sensation, redness, watering and even blurred vision. There are numerous treatments depending on the cause.

Blepharitis

A common condition characterised by inflammation of the eyelids. Symptoms include gritty, dry, irritated eyes. There is also often crusting and redness of the eyelid margins.

Pterygium

A benign wing-shaped over-growth of the conjunctiva, most commonly on the nasal side of the eyes. It is most commonly caused by UV damage and as such often affects people who spend a lot of time outdoors in the sun, including surfers. It is important to wear sunglasses to reduce the risk of development or progression of a pterygium.

Macular Degeneration

A progressive condition characterised by damage to the Macula. The Macula is the most sensitive part of the retina, responsible for central and detailed vision. The risk of developing Macular Degeneration increases with age, a family history of the condition and a history of smoking. Symptoms include visual distortions, difficulty reading or recognising faces and/or dark patches in your central vision.

Macular Degeneration is the leading cause of blindness in Australia. Early detection is critical so it is important to have regular eye examinations. Healthy lifestyle, optical sun protection, no smoking and a diet rich in omega 3s, leafy green vegetables and a handful of nuts a week also reduce your risk of developing Macular Degeneration.

Cataracts

Clouding of the lens inside the eye, resulting in blurred vision, reduced contrast and increased glare sensitivity. Cataracts usually occur in those who are older, however, can develop in younger people or infants.

Glaucoma

Progressive optic nerve disease, resulting in peripheral vision loss. It is commonly associated with an increased intra-ocular pressure. There are no obvious symptoms and as such regular eye examinations are imperative.

Floaters

Natural deposits in the vitreous humour, which is the jelly inside the eye. They often appear as spots or cobwebs in one’s vision. Floaters are usually benign but if you notice an increase in floaters or associated flashes in your visual field it is important to organise an eye examination immediately to rule out retinal detachment.

Diabetic Retinopathy

A condition where the tiny blood vessels of the retina are damaged as a result of Diabetes. This can cause distortion, blurring or even loss of vision. It is essential for Diabetic patients to have strict control of their blood sugar levels to prevent progression of Diabetic Retinopathy.
