Abstract

The invention relates to a method for inducing a controlled variation of accommodation in an eye of a subject, using an optical system arranged in front of at least one eye of the subject and comprising the following steps: a) displaying an environmental scene (1), b) displaying, in this environmental scene (1) displayed in step a), a target (2) visible by the subject through said optical system, said target (2) being displayed in such a way that it is perceived by the subject as moving away from said subject or moving towards said subject within said environmental scene, c) having the subject observe said moving target (2) displayed in step b).

Description

technical field [0001] The present invention relates to a method for inducing a controlled change in accommodation in an eye of a subject using an optical system arranged in front of at least one eye of the subject. Background technique [0002] Devices and methods for limiting the accommodation of the eyes of a subject are used in the context of determining refractive characteristics. [0003] During such a determination, it is important to limit accommodation of the eye that could affect the result of the determination. [0004] Different methods exist, such as using a fogged positive lens placed in front of the patient's eye to induce the myopic condition, or using cyclonumeral eye drops to inhibit accommodation. [0005] However, these methods are uncomfortable for the subject, who remains in blurred vision for part of the time of the examination or even longer in the case of eye drops. [0006] These eye drops should only be administered by a doctor and there is a ris...
