A vision testing device includes a light-occluding casing for administering vision tests. A viewing station is coupled to the light-occluding casing so a test subject can see a first digital display housed within the light-occluding casing. A second digital display is external to the light-occluding casing and is configured to receive touch-based input. One or more predetermined vision tests are displayed via the first digital display. The second digital display receives input corresponding to the vision test displayed via the first digital display. The second digital display includes response indicators that can be activated via a swiping motion on the second digital display, and a response is recorded as a result of the swiping motion. Each answer corresponding to a swiping motion is stored and output as a result of the vision test.

Systems and methods for vision testing

Disclosed is a method for evaluating the vision of an individual under certain brightness conditions, using a screen displaying an image including a background and characters to be deciphered which appear on the background. The method includes the following steps: a step of regulating the brightness of the background of the image; and a step of regulating the brightness of the characters to be deciphered which appear on the image, the two steps being independent from each other so as to obtain the desired contrast between the background and the characters.

Method for evaluating the vision of an individual in predefined brightness conditions

Disclosed is a centering-blocking apparatus () including: a frame (); an ophthalmic lens holder (); a blocking unit () suitable for receiving a blocking accessory () with a view to depositing it on the ophthalmic lens; and a centering unit () suitable for revealing a reference system of the ophthalmic lens. According to an embodiment, the blocking unit is fixedly mounted on the frame whereas the holder is movably mounted on the frame.

Ophthalmic lens centring-blocking apparatus

An ophthalmic-lens holder () includes a plate () and three pads () which are mounted on the plate and rise up above the latter to offer free ends () via which they can bear the ophthalmic lens. At least one of the three pads is movably mounted on the plate.

Ophthalmic-lens holder

Method of determining at least one refractive characteristic of an ophthalmic lens, includes:
