Refractive errors come in several types, commonly including myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. Generally, these are the four main categories. Regardless of the type, the treatment methods for refractive errors typically involve the following: one method is wearing frame glasses to improve or maintain good vision. Another method is using contact lenses to achieve good vision. Lastly, corrective surgery, such as LASIK, can be performed to correct the vision permanently. These are the three basic approaches.

Is refractive amblyopia easy to treat?

Early detection, treatment, and training for refractive amblyopia can potentially restore normal vision, but the extent of recovery varies from person to person. Since the principles behind various amblyopia treatment methods differ and have their advantages, comprehensive therapy is superior to single therapy. For a child with amblyopia in one eye, the routine initially involves covering the healthy eye to give the amblyopic eye more focused exercise, combined with precise visual acuity training, stimulation from amblyopia treatment devices, and so forth. After months or years of treatment, the child's vision in the amblyopic eye will show significant and rapid improvement.

Refractive error refers to an eye disorder.

There are several clinical manifestations of refractive errors, such as myopia, hyperopia, or astigmatism, all of which fall under the category of refractive errors. The normal adult eye axis is approximately 24mm, and patients with refractive errors have eye axis measurements that are greater or less than this value, which prevents images from being clearly presented on the retina. In patients with myopia, images generally appear in front of the retina, while in patients with hyperopia, images typically appear behind the retina. Various types of refractive errors can be corrected by wearing glasses to improve vision, enabling patients to see clearly. Additionally, patients with myopia and astigmatism can also consider laser surgery treatment after reaching adulthood.

How to correct refractive errors

Refractive errors include myopia, hyperopia, astigmatism, and anisometropia. The correction of myopia can be achieved using appropriate concave lenses, while hyperopia requires suitable convex lenses for correction. The correction of astigmatism depends on the degree and axis differences, so it is necessary to use lenses with the appropriate degree and axis for correction. Anisometropia, due to the significant difference in the degree between the two eyes, requires consideration of the sufficient degree and the correction of the magnification rate of the retinal image during correction.

What is the difference between refractive error and nearsightedness?

Myopia is a type of refractive error, which refers to the condition where, when the eye is not adjusting, parallel light rays after passing through the refractive action of the eye, do not form a clear image on the retina, but rather image in front of or behind the retina. This includes hyperopia, myopia, and astigmatism. When parallel light rays image in front of the retina after passing through the eye's refractive action, it is called myopia.

Refractive amblyopia can be cured

Refractive amblyopia, most cases can be cured. Most refractive amblyopia is associated with hyperopia, accompanied by amblyopia, caused by abnormal fetal development in the womb, and the specific cause is unknown. If amblyopia in children can be detected between the ages of three to five and treated in a timely manner, most cases can be cured with a good prognosis. Treatment before the age of eight has better outcomes; treatment between 8-12 years old is less effective; there is no way to treat after age 12. The principle of treating amblyopic children is based on medical optometric prescription combined with effective amblyopia training, which primarily includes threading beads, puzzles, or using amblyopia treatment devices, etc. After amblyopia is cured, follow-up is required for three years to prevent recurrence.
