An oeil-de-boeuf (French: [œj.dÉ™.bœf]; English: "bull's eye"), also œil de bœuf and sometimes anglicized as ox-eye window, is a relatively small elliptical window, typically for an upper storey, and sometimes set in a roof slope as a dormer, or above a door to let in natural light. These are relatively small windows, traditionally oval.
The optical window is the portion of the optical spectrum that is not blocked by the Earth's atmosphere. The window runs from around 300 nanometers ( ultraviolet-B ) up into the range the human eye can detect, roughly 400–700 nm and continues up to approximately 2 μm .
A flatness test of a float-glass optical window on top of a λ/10 optical flat. The window measures a flatness of 4–6 λ per inch. The window measures a flatness of 4–6 λ per inch. In optics , a window is an optical element that is transparent to a range of wavelengths , and that has no optical power .
A window is an opening in a wall, door, roof, or vehicle that allows the exchange of light and may also allow the passage of sound and sometimes air.Modern windows are usually glazed or covered in some other transparent or translucent material, a sash set in a frame [1] in the opening; the sash and frame are also referred to as a window.

Papilledema: "The underlying mechanism for visual obscurations in all of these patients appear to be transient ischemia of the optic nerve head consequent to increased tissue pressure. Axonal swelling, intraneural masses, and increased influx of interstitial fluid may all contribute to increases in tissue pressure in the optic nerve head.
Oculi: These could be open or blind, could be glazed or filled with thin alabaster.During the late Gothic period very large ocular windows were common in Italy, being used in preference to traceried windows and being filled with elaborate pictures in stained glass designed by the most accomplished Late Medieval and Early Renaissance designers including Duccio, Donatello, Uccello and Ghiberti.
The accessory visual structures (or adnexa of eye, ocular adnexa, etc.) are the protecting and supporting structures of the eye, including the eyebrow, eyelids, and lacrimal apparatus. The eyebrows, eyelids, eyelashes , lacrimal gland and drainage apparatus all play a crucial role with regards to globe protection, lubrication, and minimizing ...
One of Wilhelm Kühne's rabbit optograms from 1878. The window the rabbit was facing appears to be discernible in the image. Optography is the process of viewing or retrieving an optogram, an image on the retina of the eye. A belief that the eye "recorded" the last image seen before death was widespread in the late 19th and early 20th centuries ...
