Samora eyes are naturally accustomed and evolved to be able to see incredibly well in the dark; however, this gives them a disadvantage in sunlight. Because of this, the Samora's pupils are always a lighter color than the iris, usually a grey or white, and highly reflective. 

Samoras call their vision type "Darkvision", and the aversion to the sun "Sunblindness". 
Sunblindness effects all Samora, and they must wear protective eye-gear when in direct & indirect sunlight.
