A character in my current campaign has a severely handicapped field of vision. He can only see 30 feet, yet I have no way of limiting his token's field of vision to 30 feet. The 'emits light' option helps simulate this, but when another light source is added that the players can see, and this light source is further than 30 feet away, his token can still see it. I can not exempt players from seeing a light source that others can see, so there doesn't seem to be any current way around this obstacle. My suggested implementation would be a distance limit on the 'has sight' option just like you have on the 'emits light' option.
