Astigmatism is a type of refractive error caused by the irregularities in the shape of a person’s cornea. In this condition, the eye fails to focus the light equally on the retina leading to blurred or distorted vision. It can be present at the time of birth, or can develop gradually i...
Photorefractive keratectomy (PRK) is laser surgery to correct refractive errors of the eye. Refractive errors are common eye disorders that cause blurred vision. These errors happen when there is a problem in the refraction (bending) of light in the eye. They are often caused by an abnormal ...
Hyperopia, also known as farsightedness, is a refractive error, which causes the eye to stop refracting light properly. This prevents someone from seeing images clearly. In the case of hyperopia, light focuses behind the retina instead of on the retina. ...

In some cases, hearing loss because of the disorder can grow worse over time. Though Marshall Syndrome can cause a variety of different eye problems, myopia is by far the most common. Myopia, also known as nearsightedness, is a refractive eye error in which light enters the eye ...
What is myopic macular degeneration? Myopia: Myopia is the medial term for nearsightedness caused by an abnormally shaped eye. When the visual axis of the eye is too long, it causes light to focus on a point in front of the retina. If the visual axis is too short, however, the light...
Myopia is a kind of refractive error—an eye disorder that affects the way light refracts within the eye. In an eye without myopia, light is focused onto the surface of the retina, and an image is conveyed to the brain via the optic nerve. An eye with myopia has a bit of trouble fo...
Refractive error Arefractive erroris a problem with the way light focuses inside your eye. Common types include conditions likenearsightedness,farsightednessandastigmatism. They cause fuzzy vision that can usually be corrected with prescription glasses orcontact lenses. Around half of all Americans have...
