In the front seat. The pilot has a flat screen radar scope that shows both the planes and the weather.
But on the rear seat. The weather scope has an giant eyepiece. Perhaps glare protection?
That's not an eyepiece, it's a glare shield. The angle of the display made it susceptible to glare from light entering the cockpit. The shield made it easier to see, at night as well. My theory is that they got the idea from Star Trek. Spock had one too on his workstation on the Enterprise. 🤣
