To my knowing.
This is yet to be added to this game which is in addition to racial spot or search skills.
Low-light vision extends the distance a creature can see in conditions of low light, rather than allowing vision in no light like darkvision... . In previous editions, low-light and darkvisions were known as infravision and was used to describe the ability to detect infrared signatures...
The way I understand it..this acts as a aid to spotting sneaking or hidden (but not Invisible) foes (Taking 2/3 sneak eyes of the foe and checking again like their in Daylight not Low-Light)
Darkvision refers to the ability to see in the dark by allowing a creature to discern forms, as in normal daylight vision, only in shades of greys. It is similar low-light vision a trait more commonly found trait amongst some races.
The way I understand it..this acts as a aid to spotting sneaking or hidden (but not Invisible) foes (All the sneak eyes of the foe and checking again like their in total daylight, not Darkness.)
This means the following races would gain from Low-Light Vision.
And the Following races would gain from Darkvision.
