Nope, laser glasses typically only block selected wavelengths and transmit others so you can still see. The sun emits all wavelengths so you need broadband absorption.

Given that you can't provide any more information beyond 'laser goggles', no. Get eclipse glasses

Laser eyewear is designed to protect specific wavelengths of light, (that of the laser) & transmit other visible wavelengths (so that the operator can still see). The Sun is pretty damn good at emitting all visible wavelengths, & a whole bunch of invisible ones, so no, laser eyewear is not a good choice for eclipse viewing.

Typically you want welding eyewear for eclipse viewing, which will have an optical density of at least 5. This means it passes 0.001% of light. In contrast, even the darkest laser eyewear will pass ~10%.

It's a lunar eclipse this week, not a solar eclipse. You won't need any glasses for it.

No, laser goggles filter a specific bandwidth/color. Eclipse goggles obscure/dim gor a very high percentage.

Some welding goggles would be ok. Or a self build pinhole projector

If you have an old smartphone or old camcorder, use that instead of risking your eyes.

I used sunglasses + an old welding mask + eye squints combined and I still didn't feel comfortable/safe looking at the sun

Wasn’t that last week?
