FUNCTIONAL OPTOMETRIC DEVICE
|
Description |
Description of the device: 1. Visual occlusor. 2. Hinge. 3. Millimeter scale. 4. Optotype rail. 5 Optotype button. 6. Optotype. 7. Flashlight. 8. Longitudinal axis of the handle
The present invention relates to a device that has been designed to perform different tests in the optometric clinic without the need to change the apparatus.
The device of the invention comprises different parts, the first corresponds to the traditional occluder with which the cover test is made for the evaluation of the deviation in both eyes, both when evaluating distant vision and near vision, and that, in addition, it is used as an occluder for the evaluation of visual acuity (AV) in a monocular form. Preferably, the shape of the occluder is circular with a radius dimension between 30 and 35 mm. It can present a concave shaped surface to allow freedom of movement of the lid that remains covered.

Advantages |
Due to the shortcomings of the different optotype models, new optotypes are still necessary to provide more accurate AV measurements and less dependent on factors other than the possible visual alterations of the individuals.
