sView supports various input stereoscopic formats: side-by-side; over/under; interlaced; dual stream (or separate files); frame-sequential. Stereoscopic format is automatically deduced from a file metadata (when provided), but could be manually set by user. sView allows adjusting stereoscopic pair in horizontal, vertical and angular dimensions for compensation of camera recording defects.
Adjustable focus eyeglasses have one focal length, but it is variable without having to change where one is looking. Possible uses for such glasses are to provide inexpensive eyeglasses for people from low-income groups, developing countries, third world countries or to accommodate for presbyopia.
Since most refractions (the measurement that determines the power of a corrective lens) are performed at a vertex distance of 12–14 mm, the power of the correction may need to be modified from the initial prescription so that light reaches the patient's eye with the same effective power that it did through the phoropter or trial frame.
Switching between distance and near vision is accomplished by re-adjusting the lens, instead of by tilting and/or rotating the head. The need for constant adjustment when the person's attention switches to an object at a different distance is a design challenge of such a lens. Manual adjustment is more cumbersome than bifocals or similar lenses.

The following comparison of video players compares general and technical information for notable software media player programs. For the purpose of this comparison, video players are defined as any media player which can play video , even if it can also play audio files.
Motion interpolation or motion-compensated frame interpolation (MCFI) is a form of video processing in which intermediate film, video or animation frames are generated between existing ones by means of interpolation, in an attempt to make animation more fluid, to compensate for display motion blur, and for fake slow motion effects.
A trial frame is a tool used by ophthalmic professionals like ophthalmologists and optometrists. It is basically an adjustable spectacle frame with multiple cells, used to hold corrective lenses , and other accessories in subjective refraction (finding the correct spectacle power) and retinoscopy .
