摘要:
1. An ophthalmic device, comprising: a contact lens requiring rotational stability in the eye, the contact lens being obtained from a lens material; at least one dynamic stabilization zone integrated in the contact lens, wherein at least one dynamic stabilization zone is configured to simplify centering of the contact lens on the eye by rotation at an angle of rotation for optimal visual acuity and contains material deformable at the temperature of the eye; and the eyelids form an angle of contact with at least one dynamic stabilization zone, which changes when the eyelids move through at least one dynamic stabilization zone. The ophthalmic device according to claim 1, wherein the contact lens is a soft contact lens. The ophthalmic device according to claim 1, wherein the contact lens is a toric contact lens. The ophthalmic device according to claim 1, wherein the deformable material changes shape under the influence of eyelid pressure during blinking. The ophthalmic device according to claim 4, in which the contact angle between the eyelids and at least one dynamic stabilization zone increases with blinking, thereby increasing the rotation force acting on the contact lens until the eyelids come essentially in contact with each other , which leads to a flattening of the deformable material in at least one dynamic stabilization zone. 6. The ophthalmic device according to claim 4, wherein the deformable material contains a biocompatible fluid at eye temperature. Ophthalmologic1. Офтальмологическое устройство, содержащее:контактную линзу, требующую ротационной стабильности на глазу, причем контактная линза получена из материала для линз; ипо меньшей мере одну динамическую стабилизационную зону, встроенную в контактную линзу, причем по меньшей мере одна динамическая стабилизационная зона выполнена с возможностью упростить центрирование контактной линзы на глазу посредством вращения на угол вращения для оптимальной остроты зрения и содержит деформируемый при температуре
