Pete Beiden Field, formerly Varsity Park, is a baseball stadium on the campus of the California State University, Fresno in Fresno, California, United States. It was built in 1966. The field is the home of the Fresno State Bulldogs baseball team and named after former Fresno State baseball coach Pete Beiden. The park was redesigned in 1983 and now holds 5,757 people. Prior to the 2002 opening of Grizzlies Stadium, the park also was the home of the Fresno Grizzlies minor league baseball team of the triple-A Pacific Coast League.

Originally known as Varsity Park, the field was dedicated in 1972 to Pete Beiden, Fresno State baseball coach from 1948-1969. Beiden, who led the program to 600 wins in his 21 seasons, was inducted in 1972 into the College Baseball Coaches Association Hall of Fame.

Stadium lighting was installed in 1969 and updated in 1996. In 1983, the venue underwent a $2.2 million redesign. In 1998, a new scoreboard, PA system, and bleacher sections along both foul lines were added. In 1999, the natural grass infield was renovated. In 2004, the left field bleacher section (added in 1998) was removed to allow for indoor batting cages and a clubhouse to be built. Following the 2010 season, further renovations added a turf "halo" surrounding the infield and a new sound system.

The field of view (also field of vision, abbreviated FOV) is the extent of the observable world that is seen at any given moment.

Different animals have different fields of view, depending on the placement of the eyes. Humans have an almost 180-degree forward-facing horizontal field of view, while some birds have a complete or nearly complete 360-degree field of view. In addition, the vertical range of the field of view in humans is typically around 100 degrees.

The range of visual abilities is not uniform across a field of view, and varies from animal to animal. For example, binocular vision, which is important for depth perception, only covers 120 degrees (horizontally) of the field of vision in humans^{[citation needed]}; the remaining peripheral 60 degrees have no binocular vision (because of the lack of overlap in the images from either eye for those parts of the field of view). Some birds have a scant 10 or 20 degrees of binocular vision.

Similarly, color vision and the ability to perceive shape and motion vary across the field of view; in humans the former is concentrated in the center of the visual field, while the latter tends to be much stronger in the periphery. This is due to the much higher concentration of color-sensitive cone cells in the fovea, the central region of the retina, in comparison to the higher concentration of motion-sensitive rod cells in the periphery. Since cone cells require considerably brighter light sources to be activated, the result of this distribution is that peripheral vision is much stronger at night relative to binocular vision.
