English term or phrase: transmission

Talking about prescription glasses:
Anti-glare filters with a transmission of < 80% are not suitable for application at dawn, dusk or at night.

I'm assuming it's the transmission of light that's meant here, which would mean sth like تسمح بمرور أقل من 80 بالمئة من الضوء, however light isn't explicitly mentioned here so I don't want to make assumptions. And you can't just say تسمح بمرور 80 بالمئة full stop.
Any other word for "transmission" that's used in this context in Arabic? (Thank you for not suggesting إرسال and نقل and similar meanings of transmission that don't fit the context :-) )
Thanks!

Explanation:
What is Anti Glare or Anti-Reflective Coating? Our premium Anti-Glare/anti-reflective coating is a must for computer use and night driving. They work by increasing the light transmission through the lenses, providing you with the clearest, sharpest vision at all times.

It is reported that anti glare eyeglasses are equipped with strong light block rate 4 times to 20 times higher than ordinary sunglasses, and visible light transmission rate over 70%.

Unlike sunglasses or self-darkening lenses, which block some light, AR-coated glasses actually transmit more light - about 8 percent more. This improves vision at night and helps distinguish fine details during the day.
