I should have been clearer with my post.

Lens flare in photography and videography tends to be seen as a defect and something to be avoided. That's why lenses have use expensive chemistry for anti-reflective coatings.

When lens flare is used it should be a conscious choice.

Lens flare tends to be reserved for scenes in space. And most of these scenes are not real, but created in a computer, and the flare is added to create "realness". Well, that's fine. Sometimes it works, sometimes it's mocked. ('NEEDS MOAR LENS FLARE' has some useful web search results.)

But, for games, I tend to like lens flare, and it tends to help immersion. (If used carefully.) I have no idea why. It's probably a good idea to allow users to turn it on or off.
