The human eye's visual angle is usually 124 degrees, which when focused is about one-fifth, or 25 degrees.

The horizontal viewing angle of a human eye can reach up to 156 degrees, and the horizontal viewing angle of both eyes can reach up to 188 degrees.

The overlapping field of view of two human eyes is 124 degrees, and the comfortable field of view of one eye is 60 degrees.

The viewing angle limit of the human eye is approximately 150 degrees in the vertical direction and 230 degrees in the horizontal direction. If everything within this viewing angle range is a screen, it will give us an immersive feeling.

In reality, human vision is a sensitive area at 10 degrees. Information can be correctly identified at 10 to 20 degrees, and more sensitive to dynamic things at 20 to 30 degrees. When the vertical viewing angle of the image is 20 degrees and the horizontal viewing angle is 36 degrees,

You will have a very good sense of visual presence, and you will not be tired due to frequent eye movements.

Expanded information and content related to the human eye perspective: The video website promoted two vertical screen mini-series. Some practitioners raised objections to vertical screen movies and TV shows based on human physiological structure, believing that horizontal screens are not inherited from the history of image consumption, especially

TV and computer screens are gradually developing towards a widescreen ratio of 16:9. This is due to the "human eye visual acuity". The horizontal viewing angle of the human eye is much higher than the vertical viewing angle.

Some directors believe that the narrow field of view of the vertical screen cannot avoid peripheral light interference, which means that the audience cannot concentrate for a long time. This also makes vertical screen film and television dramas currently unable to get rid of the "short video" thinking, and most of them focus on light content,

Light production, lack of phenomenal quality works.
