SNA vision standards are manifold. Your distance visual acuity (DVA) MUST be 20/40 or better in each eye, AND correctable to 20/20. Additionally, the degree of nearsightedness cannot exceed -1.50 diopters. With a DVA of 20/50 and 20/70, you do not meet uncorrected visual acuity standards. You might be close on the diopter limit for your left eye, irrespective of your ability to get to 20/20 with corrective lenses. The ability to be corrected to 20/20 is irrelevant if you are outside the SNA baseline standards of 20/40 each eye.
You're probably within limits for refractive surgery, but a cycloplegic refraction is necessary to quantify the exact diopter numbers.
Waivers for SNA visual standards have not been recommended historically, but i have no idea as to current practice.
You are within standards for SNFO.
