Many people find themselves affected by one optical health issue or another, whether it be a common vision problem or something more complex. To further understand your basic vision problems here is an overview of common optical health issues many people face every day:

Near (or Short) Sightedness

If you are nearsighted this means that your vision allows you to see objects that are closer to you, but those that are further away are out of focus. The reason for this is that the light that comes into your eye does not focus on the retina, but instead falls in front of it. This condition is also called Myopia. Nearsightedness tends to run in families and often becomes apparent in early adolescence and in young adulthood. This optical health issue is easily corrected with glasses that compensate and assist your eyes in focusing on far away objects.

Farsightedness

Of course it goes to follow that farsightedness or hyperopia is the opposite of nearsightedness. You can see objects at a distance, but have trouble focusing on objects that are near. Farsightedness tends to run in families and is usually present at birth. Despite farsightedness appearing at an early age it is also a very common occurrence that will set in for people over 40. Glasses can correct farsightedness and those over 40 may find bifocals or progressive lenses are required.

Astigmatism

Astigmatism is a refractive error caused by your eyeball not being perfectly round. The result is blurred or distorted vision. Because the shape is more like a football or in some cases, the back of a spoon the light is refracted differently which results in darker areas leading to blurry or wavy looking objects. Again glasses can correct your vision if you have astigmatism.

Cataracts

Cataracts occur due to a build-up of protein. This affects the lens of your eye as it stops the lens from bending the light properly. Cataracts can be a result of age, but can also be caused by other health conditions such as diabetes. Babies can also be born with congenital cataracts and they can also occur due to injury. If glasses can assist in correcting your vision you will not require cataract surgery. If surgery is required your cloudy lens will be replaced by an artificial, clear lens.

Now that you have a further understanding of your common optical health issues you know what to expect in the future.
