CONDITIONS THAT AFFECT YOUR VISION
Understanding Common Eye Conditions
Eye with myopia
When the cornea is too curved or the eye’s shape is too long, the lenses of the
eye focus the image before it reaches the retina. This causes blurry vision at a
distance, which means individuals will have trouble seeing objects that are far
away.
Myopia (nearsightedness)
Myopia, or nearsightedness, is a condition where people can see better up close
than at a distance. For example, someone with myopia may not need eyeglasses to
read, but need eyeglasses to see at a distance. Myopia can vary from mild to severe.
Eye with hyperopia
When the cornea becomes too flat or the eye’s shape is too short, the lenses of
the eye focus light rays past the retina, so the image you see is blurry.
Hyperopia (farsightedness)
Hyperopia, or farsightedness, is a condition where people can have difficulty focusing
on objects up close. With hyperopia, near objects appear blurry while distant objects
are clearer.
Eye with astigmatism
If the cornea is curved more in one direction than the other (like an oval rather
than a circle), the light rays focus on several different places and not clearly
on the retina. This causes distorted images at a distance.
Astigmatism
Astigmatism is a condition where people usually can’t see clearly at any distance
because their vision is blurry. This is caused by a cornea (the outer lens of the
eye) that is unevenly shaped rather than its normal roundness.
Normal and cataract vision

Cataracts
When the natural lens inside the eye becomes cloudy or yellowed, this is called
a cataract. Cataracts typically begin forming in our 50s, although we are usually
in our 60s or 70s before they have a major impact on our vision. However, cataracts
can affect people of all ages for various reasons. Some common cataract symptoms
are: hazy or yellowed vision, faded colours, frequent changes in eyeglasses prescriptions,
difficulty with night driving, and blurry vision.
