display is fishbowled

When looking around in minecraft pc 1.7.9 the view is fishbowled. I know this might not be a problem with other users but both my little brother (6) and I get bad headaches when looking at any screen with this type of view. My brother is my main concern, he gets migrains and ends up vomitting once he gets them. I play on an older version and did not see the viewing of this version, but now that I have I can tell why he gets headaches after playing and I will be making sure he does not play this version untill the viewing is changed. I hope I helped with any problems, and if there is a way to fix it within options Iwould love to know, thank you.
