Visual acuity enhancement

Visual acuity is defined by the medical literature as acuteness or clearness of vision, which is dependent on the sharpness of the retinal focus within the eye and the sensitivity of the interpretative faculty of the brain.

This sharp increase in visual acuity can be described as a new-found ability to comprehend the entire visual field at once, including the peripheral vision. In comparison, during sober living human vision is only able to perceive the small area that a person's eye is currently focused on. This sharp increase in the level of visual detail attributed to the external environment, is consistently heightened to the point where the edges of objects become extremely focused, clear and defined.

This visual effect does not necessarily change the appearance of the external environment but rather the level of detail in which it is perceived in. During even a very low-dose trip it is common for people to suddenly notice patterns and textures that they may have never previously appreciated, or even acknowledged previously. For example, when looking at sceneries, nature and everyday textures, the complexity and beauty of the visual input suddenly becomes overwhelmingly obvious.
