Yes, you can actually have perfectly sound eyes but have trouble using them. To do a quick easy check for this (for free), have a friend wave their finger randomly around in front of your face. Try to track with your eyes (without moving your head). If your friend notices "jagged" eye movement, you might benefit from vision therapy.

I did 10 sessions of vision therapy this summer and it really helped with visual tasks such as reading & driving.

You can look for an optometrist who provides these services here:
