What is the difference between myopia and astigmatism?
myopia and astigmatism are the conditions that affect sight. Astigmatism develops when the cornea has an irregular shape, leading to a blurred vision. Myopia develops when the eyeball is too long or the cornea has too many curvature.
Two nearsightedness conditions and astigmatism often occur together. Astigmatism may also occur with a different state of sight, hyperopia or foresight. Although myopia and hyperopia are common next to astigmatism, they are not directly connected to each other and it is possible to have one without each other.
The irregular corneal shape in individuals with astigmatism prevents the light from concentrating correctly on the retina, leading to blurred vision. Astigmatism is a common state and most people have some degree of irregularity in the shape of their cornea. Individuals with a slight case of astigmatism will not require remedial lenses. Severe cases of astigmatism require correction to avoid blurry, distorted vision, eye pain, and headaches.
assumedIt is that astigmatism is a genetic state. Children can be born with astigmatism, which either deteriorates or improves during aging. Corrections for astigmatism include glasses, contact lenses and refractive correction such as laser surgery.
The name for myopia is more common. It is a problem of vision that makes it difficult to see things far, and at the same time allow individuals to see things close up closely. The condition is caused by visual stress, such as a large part of close work or genetics.
nearsightedness is most common in school age children. Over adolescent years, it gradually deteriorates and tends to cope at the age of 20, when the eye stops growing. Health conditions such as diabetes can also lead to myopia.
The treatment of nearsightedness and astigmatism is similar, with contact lenses, glasses and laser surgehes possible treatment options. One of the other treatment of a short -sightedSTI is the therapy of vision. Vision Therapy is an effective treatment for individuals who develop myopia due to visual stress.
Not all cases of nearsightedness and astigmatism are simple. Individuals with diabetes can experience changes in their vision depending on the blood sugar levels. When blood sugar is high, vision becomes short -sighted, while low blood sugar leads to hyperopia. In some cases, antibiotics may cause myopia. Some cases of nearsightedness do not cope with age, but continue to progress, which eventually leads to blindness.
Complications of astigmatism are a state known as amblyopia or lazy eye. Amblyopia is a condition that develops when an otherwise healthy eye stops evolving, leading to loss of vision. Early treatment is necessary to remedy amblyopia.
