Nearsightedness (myopia) is a common vision condition in which you can see objects near to you more clearly than objects far away. The degree of your nearsightedness determines your ability to focus on distant objects. People with severe nearsightedness can see clearly only objects just a few inches away, while those with mild nearsightedness may clearly see objects several yards away.
Nearsightedness is typically genetic and may develop gradually or rapidly, often worsening during childhood and adolescence. A comprehensive eye exam can confirm nearsightedness. An eye doctor can easily correct the condition with eyeglasses or contact lenses.
Farsightedness (hyperopia) is a common vision condition in which you can see distant objects more clearly than closer objects, while the degree of your farsightedness determines your focusing ability. People with severe farsightedness may see near objects less clearly than distant objects, while those with mild farsightedness may be able to see objects that are closer. Farsightedness can also contribute to a misalignment of the eyes because when the visual system tries to compensate for the condition, it may affect the way the eye muscles work.
Astigmatism is a common eye condition that is corrected by eyeglasses, contact lenses or surgery. Unequal curvatures of the cornea characterize astigmatism. A person’s cornea is spherical, and when light enters the eye, the cornea refracts or bends light, creating a clear image of the object. However, the eye of a person with astigmatism is shaped more like a football or the back of a spoon. For this person, when light enters the eye, it is refracted more by one curve than the other, resulting in a blurry image.
Presbyopia is an age-related condition that causes blurred near vision. It typically manifests around age 40 and affects everyone, even those who have never had vision problems before. Most experts believe presbyopia is caused by changes to the lens inside the eye. As people age, the lens becomes harder and less elastic, making it more difficult for the eye to focus on close objects. For many years, presbyopia was corrected with the use of bifocal eyeglasses. Presbyopia can now be corrected with glasses, contact lenses or surgery.
