Very simple. We need to remember the formula that will allow us to find the optical power of the lens, and from there express the main focus. Let’s use the formula that will allow us to find the optical power of the lens: D = 1 / F. From here we express F, it will be equal to the ratio 1 / D, and will be numerically equal to 1/2 – 0.5 (m)
