Shot that way for 30 years, but highest anchor point I could use was 2nd finger to corner of mouth. I usually had frames that were the "pilot" shape/variety, so not small, but not overly large.
In 2000 I had lasik. Absolutely one of the best decisions I ever made. 16 years later, still 20/20, though the reading clarity part is going downhill.
No more foggy, wet, or dirty lenses to worry about, but I never realized how many branches hit me in the face until walking through the woods in the dark with no glasses! They did provide a measure of eye protection.
