Can anyone please direct me to the formulation for calculating the amount of light transferred through a glass?
Or the amount of light absorbed.

Thank you

May be you are searching for Lambert-Beer law.

I had a look at the Lambert-Beer Law, but the text states that: The Lambert-Beer Law is valid only for diluted solutions.
I don't think glass lies in this category.
Any idea?

No, Lambert-Beer (LM) law is valid.
For example: one can apply to absorption of gamma rays in lead (for shielding calculations)
And in X-ray absorption spectroscopy LM is often used.
Also for finding attenuation of light in sun glasses, LM is used.
Hope this helps.
