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 including displaying an environmental scene, displaying, in this environmental scene, a target visible by the subject through said optical system, said target 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, having the subject observe said moving target.

Method for inducing a controlled variation of accommodation in an eye of a subject

Disclosed is a method for altering the visual performance of a subject using an optical system arranged in front of at least one eye of the subject, and including: b) determining an optotype; c) displaying the optotype to the subject in such a way that it is visible by the subject through the optical system; d) assessing the visual performance of the subject viewing the optotype through the optical system; and e) adding a positive or negative altering value of spherical optical power to the optical system. The method includes, before step b): a) choosing a target value of visual performance; and in that, at step b), the optotype has a size which is determined depending on the target value of visual performance; at step e), the altering value of spherical optical power is determined depending on the target value of visual performance.

Method for altering the visual performance of a subject, method for measuring the spherical refraction correction need of a subject and optical system for implementing these methods

Disclosed is a hoist apparatus including: an electric motor, and a control box that can be electrically powered by a power supply, the control box including at least an electronic control circuit, an electrical wiring and an external casing forming a box of the control box, the external casing including at least sidewalls and a removable lid closing the box, the control box controlling the operations of the electric motor thanks to the electrical wiring connected to the electronic control circuit, to the power supply and to the electric motor, and a monitoring device, wherein the monitoring device is an insert of the box, the monitoring device being arranged within an enclosure, the enclosure being an added part of the box or being an exchanged part of the box and wherein the monitoring device is connected to the electrical wiring.

Method for determining a value of a global sensitivity parameter of a subject, methods using this value and system for determining said value

The invention relates to a method for determining a filter for an ophthalmic lens intended for being placed in front of the eye wearer, said filter being capable of improving or maintaining the visual comfort and/or the visual performance of said wearer. According to the invention, this method includes:

Method for determining a filter for an ophthalmic lens as a function of a quantity representing a dynamic sensitivity of the eye of a wearer to a variation in a luminous flux
