Our love of the outdoors and our fantastic Queensland climate is what puts us at risk to develop this problem. A pterygium is a growth of degenerative tissue that occurs on the white of the eye and advances across the cornea (the transparent part at the front of the eye). These changes lead to discomfort, dry, irritated eyes, as well as distortion of the cornea which can result in blurred vision.
The most common causes are chronic exposure to UV light, wind, glare and dusty environments. Prevention is the key to this problem so wearing sunglasses, a hat and protective eye wear in dusty environments are very important.
