The type of double vision can be horizontal, vertical, torsional, or a combination. 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 ...
Purpose. extent of binocular functions. Bagolini striated glasses test, or BSGT, is a subjective clinical test to detect the presence or extent of binocular functions and is generally performed by an optometrist or orthoptist or ophthalmologist (medical/surgical eye doctor).

He studied under one of the founders of modern psychology, Wilhelm Wundt, and started one of the first experimental ...
Amici prism. For the reflecting prism, see Amici roof prism. An Amici prism, named for the astronomer Giovanni Battista Amici, is a type of compound dispersive prism used in spectrometers. The Amici prism consists of two triangular prisms in contact, with the first typically being made from a medium-dispersion crown glass, and the second from a ...
Diplopia can be addressed by occlusion with eye patching, frosted lens, occluding contact lens, or by simply placing opaque tape over a portion of eyeglasses. Also, plastic prisms (Fresnel prisms) can be attached to eyeglasses of a diplopic patient, allowing for alignment of vision from both eyes in the affected direction, but are often ...
In optics, a dispersive prism is an optical prism that is used to disperse light, that is, to separate light into its spectral components (the colors of the rainbow ). Different wavelengths (colors) of light will be deflected by the prism at different angles. [1] This is a result of the prism material's index of refraction varying with ...
