Can Asymmetric Eyes or Eyebrows Be Fixed?

Some asymmetries can be fixed, others cannot.
Often, one globe (eyeball) is more deeply set than another. That means that it sits more deeply in the bone of the eye (orbital socket). This in turn causes many other asymmetries. The deeper eye will have more laxity (looseness) of the overlying skin, causing the upper eyelids to appear different.
There is often on the same side as the deeper set eye a flattening of the cheekbone, again causing the eye area to look different. There may be an orbital dystopia, where the eye bones are actually at different levels.
Brows can be at diffferent levels, or have different strengths of muscles functioning to cause the brow to appear different. The whole anatomy of every bone and muscle in the face comes into play.
Differences in the set of a globe cannot, for practical purposes, be corrected. However, a plastic surgeon who carefully analyzes the asymmetries of the face can come up with a plan that minimizes the asymmetries.
Nobody is completely symmetrical. A skilled and artistic plastic surgeon can point out the asymmetries and come up with a plan to minimize them. He or she can also point out which asymmetries cannot be fixed. You should feel comfortable after your consultation that your asymmetries were pointed out, recognized, and a plan included how to reduce the fixable asymmetries as much as possible.
Overall, asymmetries can often be minimized, but never completely removed.

Great question!
You certainly have multiple options to choose from. Given your age, a less invasive option would be something like botox. While not particularly long lasting, this could give you an idea of what things may look like when made more symmetric. Surgically a brow lift or blepharoplasty would be options. There are multiple nuances to these surgical options, ie whether an endoscopic brow lift with incisions hidden in the hair line or temporal brow lift ("cat eye" lift) would be best for your asymmetries. I agree your best option to schedule a consultation with a plastic surgeon who is familiar with these procedures and you feel comfortable with!
Hope this helps and best of luck!

A degree of asymmetry of the eye sockets and eyebrows is the norm and cannot be fully overcome by surgery. When the asymmetry is more pronounced, the more common strategy is to lift the eyebrow that is lower. It is important to make it a moderate change, since the eye does not move and the distance between eyebrow and eye van become exaggerated. The non-surgical option would be to use Botox or equivalent. As surgical option, an endoscopic lift on one side is typically sufficient. If the eyebrow is more slanted laterally, a temporal lift just for the tail of the eyebrow can have good effect. Finally, threads have been used to lift the eyebrow position, with variable results. It is possible to use the technique for adjusting just one side. 

Facial asymmetry is very common, and is often noticeable around the eyes and the brows more than in other areas of the face. Brow lifting techniques can be used to correct some brow asymmetry, but this is usually less effective with the more common brow lifting techniques such as trichophytic and endoscopic brow lifts. Direct brow lifts (incisions right at the eyebrows) or mid-forehead lifts are more effective at correcting brow asymmetry, but usually result in much more noticeable scarring.
In some patients, brow asymmetry can be helped with Botox injections, but each patient is unique.
All the best,

Hi,
There may be several reasons for your stated problem each with a different answer. If the problem is with a low set eyebrow, then the best solution is a DIRECT browlift, This involves making an incision in the skin above the affected eyebrow just at the area where the hair meets the skin and lifting the eyebrow to match the other side. The advantage here is that the surgeon has maximum control in leveling the eyebrows, the disadvantage is that there will be a small surgical scar. Other browlift techniques exist that hide the scar, but you lose accuracy in where you set the brow. In some cases, the brow can be elevated with a combination of botox/dysport and fillers. There are other potential causes including a droopy eyelid, high opposite brow or a combination of all of the above. A careful examination by a facial plastic surgeon will be beneficial.
Good luck,

Yes this is correctable, although results really depend on the muscle strength and integrity. There are three muscles in play: the frontalis muscle, which lifts the brow, the corrugator, and the orbicularis, which depresses the brow. 
You can try Botox to position the brow, but in my hands surgery is likely most the most successful option. 
Hope this helps.
Best of luck,
