Reply to comment by Kr3dibl3 in Researchers have discovered that ambient light is an important factor determining eye colour across primate species, suggested that this pattern may also explain differences in eye colour in human populations by giuliomagnifico
From the article: "Prof Monteiro said, “What is exciting about this research is that by using the comparative method in evolutionary biology, we find that many species of primates independently evolved bluer eyes at higher latitudes, just like what happened within our own species. This helps tip the balance towards an ecological, rather than sexual selection explanation, for the evolution of blue eye colour in humans.
Blue light helps us tune our circadian clock to adjust energy levels by stimulating special receptors in our retina. In geographic regions with less light, bluer irises may allow more blue light to reach those special receptors, thus boosting energy levels. This would help explain why blue eyes evolved and spread only far away from the equator." So yes.

Most primates are genetically modified. They are perhaps the most feral of all the wild creatures because humans have always enjoyed keeping them as pets. There is nothing you can use them for except human epidemic models.
