About lightsaber attachment

Hey guys,

I’m new to the forum and I hope someone can help me about safety. Couldn’t find the answer searching the forum...

My spiker series 520nm 1W from Sanwu laser is on the way and I have an important question about the lightsaber attachment.

Can I see with my naked eyes (without safety goggles) the attachment at medium 600mw and high power 1W without causing eye injury?
