Approved safety glasses can be identified by __ the color of the lens the thickness of the lens the Z 87.1 logo and manufacturer's emblem the description given on the box

## Step 1<br />The problem is asking us to identify the correct method to identify approved safety glasses. The options provided are the color of the lens, the thickness of the lens, the Z 87.1 logo and manufacturer's emblem, and the description given on the box.<br /><br />## Step 2<br />The color of the lens and the thickness of the lens are not reliable indicators of the safety standards of the glasses. They can vary greatly and do not necessarily reflect the safety features of the glasses.<br /><br />## Step 3<br />The Z 87.1 logo and manufacturer's emblem are standardized symbols that indicate the glasses meet specific safety standards. The Z 87.1 logo is a standard set by the American National Standards Institute (ANSI) that ensures the glasses meet certain safety requirements.<br /><br />## Step 4<br />The description given on the box can be misleading as it can be written by anyone and may not accurately reflect the safety features of the glasses.
