Do you know why you wear
glasses? Is it because you are short-sighted, long-sighted or something
else? The topics below cover common eye conditions that are treated with
glasses, including astigmatism, myopia, hyperopia, presbyopia, and
Astigmatism is an
eye condition that results in blurred vision. It is caused by a ‘warped’
cornea (a cornea that curves unevenly, rather than curving equally in
all directions). With astigmatism your vision can be blurry at various
distances—short, middle, and long range—and can distort objects, making
them appear slanted. You can be born with astigmatism or develop it
later in life. Common symptoms include headache, fatigue, squinting, eye
discomfort and irritation.

(often called ‘short-sightedness’) is a very common eye condition that
affects nearly one-third of all Australians. Short-sightedness means
that you are unable to see objects in the distance, but are able to see
objects closer to you. It is not known what causes short-sightedness,
but it is believed that poor reading habits, spending a lot of time
looking at objects at a close distance, and poor lighting may contribute
to the problem. However, it has also been found to be more common in
children whose parents have myopia. It is often first discovered when a
child is at school and can’t focus on the board at the front of the

(often called ‘long-sightedness’) is a common eye condition affecting
nearly a quarter of all Australians. It causes nearby objects such as
books or computer screens to appear blurry, whereas objects further in
the distance are easier to see. Symptoms of hyperopia include headaches
and strained eyes as a result of looking at nearby objects for a long
period of time. Often hyperopia is something you are born with but only
becomes apparent when you are an adult. This is because your eyes no
longer have the same ability to focus and compensate for the issue.

is an extremely common eye condition that affects the vast majority of
people over forty. It is literally caused by the eye ‘aging’, leading to
decreased flexibility. Presbyopia makes it very difficult to focus on
objects at close range, including small size font on a computer screen,
phone or newspaper. Although the symptoms of presbyopia are often
confused with hyperopia (long-sightedness), presbyopia is caused by age,
whereas hyperopia can happen at any time.

are a condition that cause your eye’s lens to become cloudy. It may
start in a particular area, but with time cataracts can grow so large
that it is hard to see out of one or both eyes. Cataracts are not only a
concern of elderly people, babies can have cataracts, and you can also
develop them following an eye trauma. Early symptoms of cataracts can be
treated with strong glasses and improved lighting; however, many people
eventually opt for surgery to have the clouded lens replaced.
