Patients with esotropia will have to decide what glasses to wear for correction based on the results of the optometry examination. If the condition is caused by hyperopia, hyperopic glasses can be worn to correct the condition. If the condition is non-adjustable and the degree of hyperopia is relatively low, prismatic glasses can be worn to correct the condition. Esotropia is a common ophthalmologic disease, usually develops in childhood, the main manifestation is the direction of vision of both eyes is not parallel, when one eye looks at the target directly in front, the other eye’s vision is skewed to the inside, which seriously affects the patient’s appearance, and may cause amblyopia, double vision and other complications. The patient needs to go to the ophthalmology department of the hospital for examination in time. The doctor will determine the refractive status of the patient’s eyes by doing an optometry examination, so as to differentiate the type of strabismus. Adjustable strabismus is usually caused by hyperopia, which can be corrected by wearing hyperopic glasses. For non-adjustable strabismus, if the degree of strabismus is less than 15 prisms, it can be corrected by wearing prisms, while adjustable strabismus with a degree greater than 15 prisms should be corrected by surgery.
