Specification: Weight: 100g Frame Width: 145mm, Lens Height: 54mm Temple Length is 120mm These glasses work. Some people are unsure how to use these. They put them on and think it makes everything red and doesn't help. But the actuality provides huge contrast between colors that you normally have trouble disguising, if your red green colorblind. I put these on while taking a color test the number or shape becomes visible so easily. It is a tool. If you need a tool to help you identify colors that you normally have trouble with, then it is for you. Comment from buyer: "These glasses are dependent entirely on how bad your color vision is and what type. Do not expect a magic elixir. I will primarily use them to identify colored strands on network wire. Some colors are clearer and more defined others are not. With these glasses I can identify clearly some wires and then look below them to identify the other wires. They will serve their purpose. I did pass a color blind test with them on but it took a lot longer than a normal vision would have. Without them no way." HOW TO USE THESE: (Assumes you are Red/Green deficient.) Purple and Blue wires, they look the same RIGHT? With these you can QUICKLY tell which one is Blue and which one is Purple. How? When you put these on the Blue wire turns Black and the Purple wire lightens up a bit. Wallah! For Brown and Green wires that look the same, put these on and the Green wire turns Black and the Brown wire becomes a little lighter. Done! It works the same with other colors that we see as almost the same. Obtain a bundle of different color wires and learn how to use these. What's in the box: 1 x glasses
