Red Dot Sights have their origin from aircraft gunsights or 'collimators' where the shooter's reticle is projected on a clear lens/glass pane allowing for easier target acquisition and a clearer sight picture of a target, later adapted for smalls arms rifles, red dots exist to be incredibly sturdy, and reliable open sight picture 'optics'. Red Dot Sights(RDS) allow for faster target acquisition due to their wide-open glass nature and featuring almost unlimited eye relief as the projected reticle is reflected off of the glass and back into the shooter's eye. meaning you can see your point of aim from almost anywhere on a rifle or pistol. The AR-15 platform was adapted for use with these aiming systems back in the late 80s where the carry handle was being sidelined in favor of the distinct Flat-Top / Picatinny rail system.
