Testimonial: "That seems to have fixed the problem. Thank you very much!"
Either the eyes are seeing something as the door is closing or you need to reset the down limit tension inside the left lense cover

I recommend this to everyone with garage door opener problems:
Use the pull cord and disconnect the opener from the door.
Operate the opener and let the carrier slide back away from the door. Is the carrier moving smoothly when disconnected?
Next, lift the door by hand from the bottom to the top. Is it moving smoothly?
If not, lubricate the hubs of all the rollers on both sides of the door. Check the cable pulleys at the top sides of the door channel, lubricate them as well.
Are all cables in all the pulleys, there are 4.
After checking those things, there is a "up force" and "down force" adjustment on the opener, try increasing the "up force" by turning the adjustment in the direction of MORE force.
