What is a key challenge in bowfishing related to vision?

Compensating for the effect of refraction is a key challenge in bowfishing related to vision because it directly affects how an archer perceives the position of the fish in the water. When light travels from one medium to another, such as from air into water, it bends or refracts, creating the optical illusion that objects are at different depths or distances than they actually are. This can result in the bowhunter aiming inaccurately if they do not account for this refraction.

Understanding this phenomenon is crucial for successful bowfishing, as it allows the hunter to adjust their aim appropriately for both the depth and the location of the fish beneath the water surface. Therefore, recognizing and compensating for the bending of light is essential for accurate shooting and successful fish retrieval in bowfishing scenarios.
