The visual impairment selector menu will provide reviewers the 

opportunity to view an image with a filter applied that will 

simulate specific visual impairment conditions that center on how

an indivudal percieves colour. This menu and the image resolution 

menu will exist on an image menu toolbar below the caption to prevent

conflicts with long captions when the screen is small. 
Currently the VIS has been modelled after the image resolution/zoom 

menu. Images have been attached to demonstrate the different simulations

for the Achromatopsia, Deuteranopia, Protanopia, and Tritanopia 

conditions in the Attachment, Onion Skin, Split and Two-Up image views. 
Outstanding Tasks: 

-Apply conditions to the "Difference" revision view

-Create the Presbyopia filter

Manual testing was conducted on the attachment, two-up, split, and onion

skin view for the Achromatopsia, Deuteranopia, Protanopia, and Tritanopia
