The Fluorocarbon line is the best-known line that fish can’t see. It has similar light refraction to water. Due to the water-like refraction, fluorocarbon is suitable for all types of water clarity. In a word, fluorocarbon is a nearly-invisible fishing line that fish can’t see.

Yellow monofilament is a highly visible fishing line. You can use this line to observe the fish bites above the water. It is good to use in dirty water. But if you want to notice the fish bite, use them in clear water.


Many anglers can be amazed that the red-coloured monofilament almost disappears underwater. The red color takes on a black color depending on the different clarity of the water.

Fish only uses their brain to understand different objects, predators and food. Fish eye vision is slightly compared with human air breathing. Humans dive into the air but can’t see it. So, logically, fish can’t see underwater objects, although they live in the water. Therefore, we can say from this discussion that fish have weak eye vision.
