Long options have a positive Vega and short options have a negative Vega. When buying an option, the purchaser wants the premium to increase and when selling an option, the seller wants the premium to decrease.

This is why Vega is positive for long positions and negative for short positions. Implied volatility is defined as the market’s forecast of a likely movement in the underlying security.
Here I’m subtracting the value of delta since I know that the value of a Put option declines when the underlying value increases. As you can see in this case, when the delta of a call option goes below 0, there is a possibility for the premium to go below 0, which is impossible. At this point do recollect the premium irrespective of a call or put can never be negative. Hence for this reason, the delta of a call option is lower bound to zero.
