We apply cream, powder etc on our face but it gets irritated if those enter our eyes. Same applies for soap too. It is better to stick on to the same brand of soap as our skin will get used to it and its chemical presence. Changing the soap often is not a good thing as our body will have to adapt to the changes. Actually, we need not wash our eyes as it gets washed with our tears. At times, we will wash it with plain water but not with anything else. Accidentally if soap or cream enters the eyes then it starts paining. The only thing we can do is to be careful.
"Do not give up, things might not favour you always"
However there is a tolerance for each of our body parts. While by practice we can touch relatively warm objects by our right palm(if right handed person), but cannot touch same by other parts or eve by left hand.We eat spicy food with chillies through our mouth. Can you imagine a little chilly powder or peeper powder coming in contact with any other part of our body?
The lens of camera has to be protected from dust and scratch, where as the outer body of a camera can withstand scratch and dust.
Compare our eyes to the thin lens of our camera. It needs more protection as it does very sensitive function. So it needs more protection.
To alert us many harm is coming to our sensitive parts, body has many inbuilt mechanisms. Pain or sense of burning is one of them. Our eyes are supplied with such sensitive nerves that senses if any unwanted material reaches near the vital parts. The eyes automatically close. If something enters,then Immediately the defence mechanisms start like tears poring out and diluting that and flushing it out. Hence considering the vital nature of the eyes, body has kept the threshold limit lowest to alert warning and provoke defence.
Same principle hols for inner ear, inner throat, private parts etc. They are all more sensitive than other parts.
We really cannot compare our skin to our eyes. They have all different tendency to bear heat or cold or whatever.
Now about using brands, one should really not base their opinions on very good brands, because at just one look you cannot decide if the particular cream or soap is going to suit you or not. You need to see its ingredients and then try it once on your hands and then if found positive effects, should try on your face. The skin of the face is sensitive in comparison to rest of the body parts.
While using any soap, you should always keep your eyes properly closed, to avoid any contact with soap. Be careful and do not use any soap if it is causing irritation in your eyes, that could involve little more chemicals.
