  2. Strabismus surgery - Wikipedia

    en.wikipedia.org/wiki/Strabismus_surgery

    Treatment of the double vision depends on both the type of double vision and the ability of two eyes to work together, also called binocular function. Diplopia with normal binocular function is treated with prism glasses, botulinum injections into the muscles, or repeated surgery. [12]

  3. Diplopia - Wikipedia

    en.wikipedia.org/wiki/Diplopia

    The provider may prescribe an eye patch to relieve the double vision. The patch can be removed after the nerve heals. Surgery or special glasses (prisms) may be advised if there is no recovery in 6 to 12 months. If diplopia turns out to be intractable, it can be managed as last resort by obscuring part of the patient's field of view.

  4. Adjustable-focus eyeglasses - Wikipedia

    en.wikipedia.org/wiki/Adjustable-focus_eyeglasses

    Adjustable focus eyeglasses are eyeglasses with an adjustable focal length. They compensate for refractive errors (such as presbyopia) by providing variable focusing, allowing users to adjust them for desired distance or prescription, or both.

  5. Prism correction - Wikipedia

    en.wikipedia.org/wiki/Prism_correction

    A lens which includes some amount of prism correction will displace the viewed image horizontally, vertically, or a combination of both directions. The most common application for this is the treatment of strabismus. By moving the image in front of the deviated eye, double vision can be avoided and comfortable binocular vision can be achieved ...

  6. Strabismus - Wikipedia

    en.wikipedia.org/wiki/Strabismus

    Glasses, surgery [3] Frequency. ~2% (children) [3] Strabismus is a vision disorder in which the eyes do not properly align with each other when looking at an object. [2] The eye that is pointed at an object can alternate. [3] The condition may be present occasionally or constantly. [3]

  7. Homonymous hemianopsia - Wikipedia

    en.wikipedia.org/wiki/Homonymous_hemianopsia

    Peripheral prism spectacles expand the visual field of patients with hemifield visual defects and have the potential to improve visual function and mobility. Prism spectacles incorporate higher power prisms, with variable shapes and designs.

  8. Corrective lens - Wikipedia

    en.wikipedia.org/wiki/Corrective_lens

    A corrective lens is a transmissive optical device that is worn on the eye to improve visual perception. The most common use is to treat refractive errors: myopia, hypermetropia, astigmatism, and presbyopia. Glasses or "spectacles" are worn on the face a short distance in front of the eye.

  9. Fixation disparity - Wikipedia

    en.wikipedia.org/wiki/Fixation_disparity

    Eye glasses with an included prism power is the optical method to reduce a fixation disparity. Different procedures have been proposed to determine the required amount of prism for the individual. Based on prism-FD curves (Fig. 3b), one can find the aligning prism sP 0 that nullifies the naturally prevailing fixation disparity sFD 0. This test ...

  10. Suppression (eye) - Wikipedia

    en.wikipedia.org/wiki/Suppression_(eye)

    Suppression of an eye is a subconscious adaptation by a person's brain to eliminate the symptoms of disorders of binocular vision such as strabismus, convergence insufficiency and aniseikonia. The brain can eliminate double vision by ignoring all or part of the image of one of the eyes. The area of a person's visual field that is suppressed is ...

  11. Prism cover test - Wikipedia

    en.wikipedia.org/wiki/Prism_Cover_Test

    The prism cover test ( PCT) is an objective measurement and the gold standard in measuring strabismus, i.e. ocular misalignment, or a deviation of the eye. [1] It is used by ophthalmologists and orthoptists in order to measure the vertical and horizontal deviation and includes both manifest and latent components. [1]
