Generally, patients with esotropia can wear defocus lenses, but the suitability of these lenses can only be determined after the patient has been fitted with them. The purpose of off-focal lenses is to eliminate peripheral defocus to control and slow down the increase of myopia as much as possible. Generally, patients with occult strabismus can wear off-focal lenses, and it will not aggravate the occult strabismus. However, it takes some time to get used to the out-of-focus lenses, so patients need to try on the out-of-focus lenses to determine if they are suitable for wearing them. Patients with occult strabismus can also choose to wear progressive multifocal lenses. When patients look at near objects, because progressive multifocal lenses can appropriately reduce the patient’s adjusting force, so that the patient’s collecting reflexes are correspondingly weakened, which is also helpful for the improvement of occult strabismus. It is recommended that myopic patients should consult the hospital in time to assess their condition, follow the doctor’s instructions for treatment and wear appropriate glasses.
