The photo is not straight. It appears as if the camera angle is above and you are looking up. Often, a small amount of scleral show is normal --- but I think that the appearance is photographic and not real. It does not appear as if any surgery is needed or would be useful.
The position of your lower eyelid can be repositioned with surgery so that the margin is closer to the lower aspect of your iris. If this is corrected, you may want to consider levator advancement surgery, as well, to elevate the margin of you upper eyelid so that it sits higher on the iris. Thanks for sharing your photo and question. Best wishes.
