Description

Technical Field

[0001] This utility model relates to the field of optical devices, and in particular to an optical strabismus correction device with adjustment function. Background Technology

[0002] Strabismus refers to an abnormal eye position where the visual axis of the other eye deviates from parallel when one eye is fixating. Causes include congenital malformations, neuromuscular disorders, trauma, and secondary systemic diseases. Common treatments include surgery, corrective lenses, and medication. Strabismus not only affects appearance but can also damage binocular vision, leading to psychological distress. Treatment primarily includes surgical and non-surgical methods. Surgical treatment involves selecting the extraocular muscles requiring surgical adjustment based on the cause, direction, and angle of strabismus, as well as examination results. This is achieved by cutting, repositioning, or suturing to lengthen or shorten the muscles, adjust their point of application, and alter their traction on the eyeball, thus correcting the strabismus.

[0003] Optical therapy includes wearing eyeglasses and prism therapy. Visual axis correction training mainly refers to binocular visual function training. Current optical strabismus correction devices are relatively simple and inconvenient to adjust the angle of the device or the optical lenses, which affects people's use. Therefore, we propose an optical strabismus correction device with adjustment function to solve the above problems. Utility Model Content
