2 days ago Bad Dream: Coma, one of the most intriguing indie horror games of recent years, will hit Xbox One and Xbox Series X/S on April 20th. It’s a point-and-click adventure game distinguished by its dark and disturbing atmosphere, a nightmarish setting and a non-linear story with numerous choices. Coma may occur as a complication of an underlying illness, or as a result of injuries, such as head trauma. Individuals in such a state have lost their thinking abilities and awareness of their surroundings, but retain non-cognitive function and normal sleep patterns. Read Coma (Steve Rogers x reader) from the story Readers Assemble! By MegLPie (Meg) with 6,578 reads. Fanfiction, marvel, oneshots. Myxedema (crisis) coma is a loss of brain function as a result of the severe, longstanding low level of thyroid hormone in the blood (hypothyroidism). Myxedema coma is considered a rare life-threatening complication of hypothyroidism and represents one of the more serious sides of thyroid disease. What are the symptoms of hypothyroidism?

Coma is an aberration which causes rays from an off-axis point of light in the object plane to create a trailing 'comet-like' blur directed away from the optic axis (for positive coma). A lens with considerable coma may produce a sharp image in the center of the field, but become increasingly blurred toward the edges. For a single lens, coma can be partially corrected by bending the lens. More complete correction can be achieved by using a combination of lenses symmetric about a central stop. |
Hecht, 2nd Ed in Sec 6.3 on aberrations gives a careful discussion of coma. For positive coma, rays from an off-axis object through larger radii of the lens contribute a larger oval of light further from the principal focus. |

Coma is shape-dependent, so a lens shape can be found with zero coma for a given object distance. That lens would not be optimum for other object distances. |
For more versatile correction of coma, one can use a combination of two lenses, both of which are corrected for zero coma at infinite object distance. The appropriate separation of these two lenses can correct for coma at various object distances. Coma can also be corrected by an appropriately placed stop, but the placement and size of an optimum stop also depends upon the other aberrations.
