Dear student 
As light passes through the glass so we see anything across it easily so, glass is transparent.
The reason is basically that the index of refraction of the glass is very nearly uniform on distances as large as the wavelength of light. That means that the light waves transmit smoothly, not bouncing off different directions. Although the individual atoms in the glass would scatter the light in different directions, just as a stick in water will scatter a water wave. However if you put a lot of regularly placed sticks in water, much closer than the wavelength of the water wave, the scattered waves from the different sticks will not be in phase except in the forward and backward directions. That means that when you add the waves in other directions the crests and troughs will cancel.
Good Luck
