It would be very unusual at your age to have an insurable amount of visual field obstruction, but not impossible. The Visual Field Tests are simple tests that have to be done by an ophthalmologist, not by a plastic surgeon.
If you have an ophthalmologist, they can arrange for you to have it done and then you can see if you are insurable. Expect major resistance from your carrier, however, as they will likely be skeptical of your "medical necessity" for an upper blepharoplasty.
Fortunately, the costs of upper lid surgery are among the lowest of all facial cosmetic surgeries and the results are great!
