On the topic of WFH eye strain but less on lighting.

There was a post a while back where the author proposed using a laser projector as a means of reducing eye strain.

She referred to lighting as a factor but I assume the major benefit is the increasing distance to the screen such that your eyes are focused on a point much further away than conventional screens (and I assume eye strain is not linear with distance).

Is there any evidence on this topic? Assuming space is not a problem why is a projector arrangement not more popular? (for office work where people don't care about colour accuracy)
