Specs listed are wrong.

These are a great pair of glace glasses. Well made. Fit secure and will not budge. Creates a great, comfortable seal with the face. They are very heavy for glasses. All metal and glass. The light reduction listed is wrong. They only reduce 87% not 95 as listed. Would definitely not recomend for high altitude.
