'''Acuity suppression''' can be described as the experience of a person's sense of vision becoming partially to completely blurred and indistinct.<ref>Hollister L. E. (1984). Effects of hallucinogens in humans,” in Hallucinogens: Neurochemical, Behavioral and Clinical Perspectives, ed Jacobs B. L., editor. (New York, NY: Raven Press), 19–33.</ref><ref>Masters R. E. L.

Depending on its intensity, this can often result in a reduced ability to function and perform basic tasks which necessitate the use of sight.  
'''Visual acuity suppression''' is defined as the degradation of the sharpness and clarity of vision, resulting in vision becoming partially to completely blurred and indistinct.<ref name="B.Sc.Buncic2018">{{cite journal|last1=B.Sc.|first1=Joanne L. Smith|last2=Buncic|first2=J. Raymond|title=Drugs Which Can Affect near Vision: A Useful List|journal=American Orthoptic Journal|volume=49|issue=1|year=2018|pages=180–190|issn=0065-955X|doi=10.1080/0065955X.1999.11982210}}</ref> This effect may affect the entirety of the person's vision or specific sections of it. The experience of this acuity suppression is comparable to looking through an out of focus lens which degrades the detail one can see in the external environment. Depending on its intensity, this can often result in a reduced ability to function and perform basic tasks which necessitate the use of sight.  


Acuity suppression is often accompanied by other coinciding effects such as [[double vision]]<ref>Smith, J. L., & Buncic, J. R. (1999). Drugs which can affect near vision: a useful list. American Orthoptic Journal, 49, 180-190. https://uwpress.wisc.edu/journals/pdfs/AOJ_49_178.pdf</ref> and [[pattern recognition suppression]]. This effect is most commonly induced under the influence of [[dosage#common|moderate]] [[dosage|dosages]] of [[depressant]] and [[dissociative]] compounds, such as [[alcohol]], [[quetiapine]], [[ketamine]], and [[DXM]].
