Safety glasses for every wavelength

Hello!

My question is, are there protective glasses for lasers that pretty much cover the entire visible range?
Can you recommend such glasses that can be purchased in the EU?
It would be a bonus if I could wear it comfortably even though I wear glasses.

Thanks!

No, they don't exist. if you lowered the intensity of all wavelengths of light that would be like wearing glasses that are very very nearly solid black, you would have almost 0 visible light make it through and you would effectively be blind.

You can however get 2 pairs that between them will cover most normal laser wavelengths, but they will have to be partially transparent in some part of the spectrum or you can't see with them

Can you give me some glasses recommendations for these 2 pairs?

At the Thorlabs link below you can get an idea of what range different laser safety glasses cover and how the covered range can vary in the level of protection, research carefully before you trust a pair of glasses to be certain they will adequately attenuate the wavelength of light you will be working with.
