If there is no refractive error, which refers to myopia, hyperopia, and astigmatism, there is no need for lenses for myopia, hyperopia, and astigmatism. However, if there is a small strabismus, such as horizontal strabismus, a prism can be used to correct it. If you have myopia, you also need to wear glasses for myopia; if you have farsightedness, you need to match the mirror for farsightedness; if you have astigmatism, you need to match the mirror for astigmatism.
Strabismus is generally divided into common strabismus and paralytic strabismus. The characteristic of common strabismus is that there is no obstacle to eye movement, and there is no diplopia, that is, no one thing is seen as two, eye movement can be moved in all directions, and there is no obstacle to movement. Paralytic strabismus refers to an eye movement disorder, such as being unable to move in a certain direction, which is often caused by eye trauma, head trauma, or some neurological diseases.
For large degrees of strabismus, it can be treated by surgery. For paralytic strabismus, it is generally necessary to use other treatment methods to see if it can be recovered, such as using some neurotrophic drugs, or removing some neurological causes. If it does not recover for more than half a year, the paralytic strabismus can also be treated with surgery, but this surgery can only ensure that the eyes are in the right position when looking forward, and those who cannot move in a certain direction still cannot move. This is an explanation for strabismus.
What lenses do you wear for strabismus?
First of all, it is necessary to do a refraction examination to the patient to see if there is myopia, hyperopia, or astigmatism. If there is any, it should be equipped with corresponding lenses. After these refractive lenses are used, if there is still a small degree of strabismus, you can put it on the lens. Add a prism to correct strabismus. Secondly, if the degree of strabismus is relatively large, surgery is required for treatment.
