X-rays can penetrate or pass through most of your body but are absorbed by your bones, so that you can see your skeleton inside your body. Can visible light also penetrate your body?

When looking through the glass, as the glass gets thicker the faint green color becomes more noticeable and light transmittance drops. Tinted glass - heat absorbing glass is made by adding color pigments to the raw materials in the float process. Imported glass may be in non-standard colors. The color density is a function of thickness, as the glass gets thicker the density of the color increases and the amount light transmittance decreases.
