Driving bridles are much stouter than your riding models. We actually long-lined Apache with an 'open' bridle (no blinkers) but this was a fitting session to show me how the eye wants to be very centred to the middle of blinker and not interfere with any eyelashes or their 'feeling' hairs. The browband comes actually quite a bit more forward and off the forehead, as it has to support the inner wired blinker adjusters that run from the crown of the bridle to the blinkers. Blinkers, it seems, have very many opinions attached to them - more later another time on that subject!
