Each person has their own sensitive body part, but some body parts overall are more sensitive than others. Eyes are not the most sensitive. It is hard to believe that the fingertips are the most sensitive. If you imagine, you get debris in your eyes. It may be uncomfortable, but it doesn’t make you wince in pain. Squeezing your fingers or pinching them may make you wince.
There are also other body parts that are close to the sensitivity like the fingertips. These do include the eyes, tongue and lips. Whenever you injure those parts, you will take notice compared to other parts of the body that aren’t affected as much. There are also parts of the body that have protection like the eyes; they have eyelids for protection.
