Here we have a unique and special product that will help those of you who want to take that extra step in preventing any damage done to your eyeglass lenses when changing nose pads. The Fish is a 1.5mm thick slab of silicone with three slots strategically placed to pass the nose pad arm through. If you look at the photos, you can see that the nose pad attached to the nose pad arm is inserted through one of the slots on the Fish. The one in the photo used the middle slot due to the width of the nose pad. As the silicone Fish is made to stretch to get around the nose pads, the best practice in getting the nose pads through the slot is to start at the bottom of the nose pad and work the rest of the nose pad along with the attaching nose pad arm through the slot. This way the pad can easily pass through with less chance of ripping the Fish by passing the width instead of the length of the pad being inserted sideways through the slot. The Fish is a tough silicone and will withstand a screwdriver blade stabbing the Fish. This is common when changing nose pads with screws especially for the inexperienced hand. Now you can worry less about scratching or gouging those expensive eyeglass lenses with the protective cover of the Fish on your side. Below is a guide giving an estimation as to what size nose pads can fit through what slots;
As you will notice in the picture, the Fish has three slots. Each slot has a number. Those numbers tell how long the opening(slot) is.
#4 The 4 slot should allow all small nose pads typically under 13mm nose pad lengths as they are generally smaller in width.
#6 The 6 slot is going to be your average, most used slot when changing nose pads. This slot will be common among 13mm pads and some slightly larger nose pads.
#8 Use the 8 slot when you are dealing with large nose pads, generally 17mm and more.
When unsure to use the number 4 or 6 slot, it may be best practice to use the number 6 slot as long as there is not a lot of open space in the opening after the nose pad arm has been fully inserted into place. You should know that the Fish is in place when the Fish can lay flat against the back of the lens.
Also, the Fish will only cover the lens that you are covering. You will need to place the Fish into position for each lens.
As this will be widely used for screw in mount nose pads, this lens protector will also come in handy for the clip on mount nose pads.
