I installed this in my mask on the right side. For me it is unobtrusive. You probably won't notice it when you start diving. When you need to read data from a gauge, watch, or computer, just hold it in front of the lens. The kit does not include silicone adhesive that can be ordered or purchased locally. When installing, make sure the inside of the Nask lens is clean and dry. Make a VERY small swab on the lens of the loupe. Put a magnifying glass on your finger and put your scuba mask on your finger so you don't accidentally drop it in the mask in the wrong place and make a mess. After it sticks to the lens of the mask, turn it over and place it on a hard surface like a table with a towel (to avoid scratching the mask) and position the magnifying glass exactly where you want. I hope you were very close within a millimeter or two. Press down VERY firmly (without moving sideways) until the silicone rests on the outer perimeter of the loupe. You may have to push slightly away from the center to align it. If you use too much silicone, it will squeeze out of the magnifying glass. In this case, wait for it to dry (24 hours), then, being careful not to scratch the mask, remove the excess with tweezers. Hopefully it won't be too much. Less is better as it will spread if you press hard enough just don't push the mask lens out! The thinner the silicone, the better the look. I don't notice any distortion. I pressed very hard with a stroke the size of a big BB, the size of an eraser, roundness not length. It's hard to get short, just keep working on the pressure. If you are confused, remove the magnifying glass and wait 12 hours to remove it. It will be a mess if you try to clean it up right away. Do not attempt to wipe fingerprints until they are completely dry within 24 hours. After 10 dives it's still there.
