Busting Common Eye Myths

Can carrots help you see better?

I’m sure we’ve all heard it before, carrots are here to save the day and cure us of all our eyesight problems. But is it true?

We are busting this myth wide open and we are happy to report that yes carrots can contribute to better eye health. Eating carrots will provide you with the small amount of Vitamin A needed for good vision, but they are one of many natural sources of Vitamin A – which is essential for keeping your eyes healthy! Milk, fish, broccoli, sweet potatoes, pumpkin and dark-green leafy vegetables such as spinach, kale and silver beet are all rich sources of Vitamin A.

Making sure your diet is jam-packed with Vitamin A can help lessen the chance of developing night blindness as well as other eye problems including vision loss. While not common in Australia, vision loss due to a lack of Vitamin A can still occur if your diet is particularly poor. Those most at risk are adults and children with restricted diets, pregnant women and those with bowel disease.

As one of the most common eye myths, eating carrots is an easy way to maintain and contribute to better eye health. Eating a healthy, well balanced diet contributes to your overall health and wellbeing as well as your eye health. Other important dietary nutrients for eye health include; Omega-3 (sources include all fish and shell fish, fish oils containing liver and butter), Zinc (sources include oysters, seafood, nuts and legumes), vitamin E (sources include nuts and whole grains), vitamin C (sources include citrus fruit, berries and tomatoes), and selenium (sources include nuts).

The Precious Gift of Sight – Donate Life

The Precious Gift of Sight

Did you know that the first ever successful organ transplant occurred in 1905! This was a cornea transplant performed in Austria and at a time where there were no medications and no anesthetics. Both eyes were operated on, and one of the transplants worked giving this blind man vision for over 40 more years.
Cornea donation is a gift of sight possible by most people within the community, last year in NSW / ACT the Lions NSW Eye Bank had 424 donors that made this sight saving decision. The gift from these people and the support from their families allow the gift of sight to more than 700 patients within our community. In NSW we have highly trained corneal surgeons who are able to perform sight saving surgery with these donations.
At Focus Eye Centre our surgeons also perform such transplants and we would like to thank the donors and their families also for their precious gift.
If you wish more information about eye and organ donation please follow the link to the Donate Life website. Please consider also being a organ/tissue donor.

Refractive Error – Symptoms, Diagnosis and Treatments

What are Refractive Errors ?

If your eye is out of focus it could be due to refractive error. This occurs when light rays do not properly focus on the retina.

Cataracts – Causes, Symptoms, Diagnosis and Treatments

What are cataracts ?

Cataracts are a clouding of the crystalline lens of the eye. This in turn affects vision. Cataracts form for many reasons but the most common is age.  It is normal for people over the age of 65 to have some mild form of cataracts. Causes of Cataract development include age, steroid use, trauma, radiation, or as a result of other eye conditions such as glaucoma.  Cataracts can occur in one or both eyes, sometimes years apart, but it cannot spread from one eye to another.

Keratoconus – Causes, Symptoms and Treatments

What is Keratoconus ?

Keratoconus is a thinning of the central zone of the cornea, the front surface of the eye. As a result of this thinning, the normally round shape of the cornea is distorted and a cone-like bulge develops, resulting in significant visual impairment. The cause of keratoconus remains unknown, although recent research seems to indicate that it may be genetic in origin. Certain allergic and arthritic disorders, Down’s syndrome, chronic eye rubbing, overexposure to sunlight and contact lens wear have occasionally been associated with this condition.

Pterygium – Causes, Symptoms, Diagnosis and Treatments

What is Pterygium ?

A pterygium is a triangular shaped growth that covers the white part of the eye. It typically presents near the inner corner of the eye and can encroach onto the cornea towards the pupil.
It is composed of conjunctival tissue and can affect one or both eyes. The main cause of a pterygium is exposure to ultraviolet rays from the sun.

Glaucoma – Causes, Symptoms, Diagnosis and Treatments

What is Glaucoma ?

Glaucoma is an eye disease which can damage the optic nerve. It typically occurs in people over the age of 60 and those with a family history. They have a build up of pressure inside the eye which results from either too much fluid formation, or a problem with drainage. This pressure in turn damages the delicate optic nerve fibres resulting in vision loss or even blindness. There are many types of glaucoma, but the most common is Chronic Open Angle Glaucoma  ( COAG ).

Ptosis – Causes, Symptoms, Diagnosis and Treatments

What is Ptosis ?

Ptosis is a drooping of the upper eyelid. The lid may droop only slightly, or it may cover the pupil entirely. In some cases, ptosis can restrict and even block normal vision. It can be present in children as well as adults.

Do you have Diabetic Eye Disease ?

What is Diabetic Retinopathy ?

Diabetic retinopathy is a complication of diabetes and a cause of blindness in Australia and worldwide. It results from damage to the fine blood vessels behind the eyes as a result of the diabetes. Bleeding or haemorrhage occurs when the new weakened blood vessels form and cannot sustain normal flow. Fluid can leak into the macular area which is responsible for clear, central sight. This in turn causes swelling or cystoid macular oedema (CMO). A healthy macula and retina are both vital for good vision.

Macular Degeneration – Causes, Symptoms, Diagnosis and Treatments

What is Macular Degeneration ?

The macula is a small central area of the retina. Structures in the macula are specialised for high acuity vision. The macula is important for reading, driving, recognition of faces and fine detail. Damage to the macula, such as Macular Degeneration, can lead to a loss of central vision.
