Visually Impaired - V2.2 Yard Garden Flags | Single Or Double-Sided | 2 SizesThis version is black and red on a white background. Version 2. 1 is a white eye on a black background. I used the symbol of a stylized eye with diagonal lines through half, and a longer diagonal as a slash mark though the centre, which is commonly used to represent blindness and visual impairment.
