  2. Pinhole occluder - Wikipedia

    en.wikipedia.org/wiki/Pinhole_occluder

    A pinhole occluder is an opaque disk with one or more small holes through it, used by ophthalmologists, orthoptists and optometrists to test visual acuity. The occluder is a simple way to focus light, as in a pinhole camera, temporarily removing the effects of refractive errors such as myopia. Because light passes only through the center of the ...

  3. Pinhole (optics) - Wikipedia

    en.wikipedia.org/wiki/Pinhole_(optics)

    This effect is also used in pinhole occluders, which are used by ophthalmologists, orthoptists, and optometrists to test visual acuity. The same principle has also been applied as an alternative to corrective lenses: a screen of pinholes is mounted on an eyeglass frame and worn as pinhole glasses.

  4. Subjective refraction - Wikipedia

    en.wikipedia.org/wiki/Subjective_refraction

    An occluder is placed over the eye that is not being tested (e.g.: over the left eye, to test the right eye's vision). A pinhole occluder is then placed before the patient's eye, and their vision is then tested again (each eye separately) to determine if the patient's poor visual acuity is a result of optical irregularities, or pathological issues.

  5. Haidinger's brush - Wikipedia

    en.wikipedia.org/wiki/Haidinger's_brush

    One such apparatus utilises a rotating polarised plate backlit with a bright white light. Wearing blue spectacles (to enhance the Haidinger's brush image) and an occluder over the other eye, the user will hopefully notice the Haidinger's brush where their macula correlates with their visual field. The goal of the training is for the user to ...

  6. Binasal occlusion - Wikipedia

    en.wikipedia.org/wiki/Binasal_occlusion

    According to a 2017 paper, [3] another hypothesis of the effectiveness of binasal occlusion in the treatment of Post Trauma Vision Syndrome, is the tape provides a stationary reference point that the brain can use to help decode the incoming visual information. The term Visual Motion Sensitivity is coined in this paper.

  7. Ambient occlusion - Wikipedia

    en.wikipedia.org/wiki/Ambient_occlusion

    3D animation of ambient occlusion enabled on the animation to the right. In the absence of hardware-assisted ray traced ambient occlusion, real-time applications such as computer games can use screen space ambient occlusion (SSAO) techniques such as horizon-based ambient occlusion including HBAO and ground-truth ambient occlusion (GTAO) as a faster approximation of true ambient occlusion ...

    Cosmopolitanism- This tool focuses on equal distribution of classroom responsibility, so that the class benefits and progresses. Context- It is the use of certain behaviors of outside of the classroom, in the classroom. This makes learning effective as the students are as comfortable as they would be outside of the classroom environment.
