Your photos are helpful but due to the angles taken and with eyes closed, difficult to base a recommendation on. Your brows do not appear low but only you can really decide how you wish for your brows to appear. If you have a crisp crease with your eyes open, your blepharoplasty did what it was supposed to. Age alone isn't a contraindication to surgery but you must be absolutely certain of what you want before jumping in.
You have brow asymmetry. That is clear. There is not "right age" for a forehead lift. They are performed based on aesthetic needs. You may very well be a great candidate for an endoscopic forehead lift. When you are ready, I recommend that you get some second opinion and determine who makes sense to you.
Either or both of these surgeries may be appropriate for you. I would have to examine you.

A front view with your eyes open would be very helpful. From this photo, your brows seem to be in a good position above the bone. You would need a consultation so a surgeon can show you how you would look with the brows elevated with a browlift. If you like that look then you would be a candidate for the surgery. Sometimes patients think their brows will look too high, and therefore should wait. It looks like you might have a little extra skin still, but would only be worth taking that out if you can see it with the eyes open.
