'''Acuity enhancement''' ~~can be described as an enhancement~~ of the clearness and clarity of vision. This results in the visual details of the external environment becoming sharpened to the point where the edges of objects become perceived as extremely focused, clear, and defined. The experience of acuity enhancement can be likened to bringing a camera or projector lens that was slightly blurry into focus. At its highest level, one may experience the perception that they can now observe and comprehend their entire visual field simultaneously, including their peripheral vision. This is in contrast to a sober person, who is typically only able to perceive the small area of central vision in detail.<ref>Sardegna, Jill; Shelly, Susan; Rutzen, Allan Richard; Scott M Steidl (2002).

While under the influence of this effect, it is very common for people to suddenly notice patterns and details in the environment they may have never previously noticed or appreciated. For example, when looking at sceneries, nature, and everyday textures the complexity and perceived beauty of the visual input often becomes suddenly obvious.
