The invention relates to a device for measuring the subjective refraction of a person in near and/or medium vision, which comprises, according to the invention, for each eye of the person, a correction mounting () provided with at least one corrective lens, the correction mountings () being arranged such that the person looks through the lenses. The position of each correction mounting () is variable such as to adjust an angle (a) between the axes of the lenses.

Device and method for measuring subjective refraction

Device and method for determining an objective eye refraction parameter of a subject depending on a plurality of gaze directions, the device includes elements for ophthalmologically measuring an objective eye refraction parameter of a subject, and elements of visual stimulation of variable proximity and intended to stimulate the visual accommodation of the subject for first and second proximity values. The device includes opto-mechanical alignment elements for carrying out a first optical alignment of the optical axis of measurement on an eye axis in a first measuring position corresponding to a first angle of lowered viewing associated with a first proximity value to take a first measurement of an objective eye refraction parameter of the subject, and a second alignment of the optical axis of measurement on the eye axis in another measuring position corresponding to another angle of lowered viewing associated with another proximity value to take a second measurement.

Device and method for determining at least one objective eye refraction parameter of a subject depending on a plurality of gaze directions

A method to assess objectively visual characteristics of one eye () of a patient () comprising the steps of: a) positioning the patient's () head in a reading position, b) determining the visual characteristics by using a device () arranged to assess objectively visual characteristics of the eye (), the device being arranged to emit a light beam (). Relates also to a system for assessing objectively visual characteristics of one eye () of a patient () comprising:&#x2014;a head support arranged to position the patient's () head in a reading position, a device () arranged to assess objectively visual characteristics of the eye (), the device () being arranged to emit a light beam ().

Method and system to assess objectively visual characteristics

The invention concerns a support of the type comprising at least a first base ( ), and, borne by the latter, for maintaining such an optical lens ( ) at its edge ( ), at least three support pins ( A, B). The invention is characterized in that the base comprises, for its own support, a plane support surface ( ) whereof the peripheral outline (P ) is globally circular, its radial dimension (D ) along a particular radius (R) of said support surface ( ) is at least equal to its axial dimension (D ) perpendicularly to the plane thereof. The invention is particularly useful for maintaining an optical lens in a processing apparatus using spin coating technique.
