Prepare corrective children's eyeglasses for children with hyperopia and treat strabismus. These glasses usually have a high degree of hyperopia, not only to improve vision but also to train eye muscle strength. Therefore, they are often not suitable for initial use and require a period of adaptation before they can be accepted.

High anisometropia with cheap eyeglasses near me is a condition in which the patient's eyes have a significant difference in refractive power. In order to reduce discomfort caused by excessive anisometropia, sometimes the eyes with poor vision are corrected too much during glasses fitting. Therefore, initially wearing glasses may also cause discomfort, but after a period of time, they can adapt.

The large difference in refractive power between the new and old glasses can cause discomfort when wearing them. This is because the difference in refractive power between the new and old glasses results in different magnifications when enlarging or reducing objects.

In addition, there may be differences in the refractive index, dispersion coefficient, pupillary distance, vertical deviation, distance between the eyes, and tilt angle of the new and old glasses. Therefore, if you are not used to them and feel uncomfortable, you will adapt after using them for some time, and the cheap eyeglasses near me symptoms will naturally disappear.

When viewing an object through a convex lens with a larger curvature, one may feel that the lines become "concave"; When viewing an object through a concave lens, one may feel that the lines become "convex". This is a phenomenon caused by negative distortion and orthodontic distortion, respectively.

For patients with non spherical lenses, this situation may be alleviated, but the edge degree of non spherical lenses is low, and the vision for looking around, below, and up close may not be sufficient.
