1. Myopia

You are probably thinking to yourself right now that you have never heard of myopia. Myopia is the medical term for near-sightedness. Unfortunately, millions upon millions of people suffer from myopia. If you have myopia, you would likely have a hard time viewing objects that are far away. People who suffer from myopia have an eyeball that features an elongated shape, which causes light to focus directly on the retina itself instead of the surface of the eye. Many people who have myopia develop headaches from trying to strain their eyes to view far away objects. Luckily, myopia can easily be corrected with a pair of contact lenses or glasses. If you have no other eyesight problems, you can even get lasik surgery to fix your myopia, which means you won't have to wear glasses or contact lenses.

2. Hyperopia

Hyperopia is the complete opposite of myopia. While myopia is nearsightedness, hyperopia is farsightedness. If you suffer from hyperopia, then you will likely have a hard time viewing objects that are close to your face. People who are diagnosed with hyperopia have a short eyeball, which causes light to fall behind the retina instead of the eye surface. Like myopia, hyperopia can easily be treated with a pair of glasses or contact lenses. Although lasik surgery is not generally used to treat hyperopia, refractive surgery is. Like lasik surgery, refractive surgery is a minimally invasive procedure that is performed as an outpatient procedure at your eye doctor's office.

3. Astigmatism

You can have astigmatism if you have myopia or hyperopia. People who have astigmatism will generally have blurred vision most of the time. The cause of astigmatism is having an oblong shaped eyeball. Of course, the eyeball should have a spherical shape. With a spherical shaped eyeball, there is only a single light point that focuses on the retina. Those who have astigmatism get blurry vision because the oblong shape of the eyeball causes 2 light points to focus on the retina. In addition to blurriness, symptoms that those who suffer from astigmatism might experience include eye irritation and discomfort, fatigue, and headaches. The most common form of treatment for astigmatism is a pair of glasses or contact lenses that are specifically designed for astigmatism. Depending on the condition of your eye, refractive surgery may be another treatment option.
