Blurry London by Josikins - This image serves as an accurate replication of acuity suppression as seen from the golden jubilee footbridge in central London.

Acuity suppression can be described as the experience of a person's sense of vision becoming partially to completely blurred and indistinct. This effect may affect the entirety of the person's vision or specific sections of it. 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[1] and pattern recognition suppression. This effect is most commonly induced under the influence of moderate dosages of depressant and dissociative compounds, such as alcohol, quetiapine, ketamine, and DXM.
