| A laser without an IR filter will produce IR radiation which can bounce off surfaces and go into your eye without your knowledge of it happening. Essentially it would be like shining the laser into your eye without you knowing about it. There are things you can buy online that measure a lasers power but if the laser you bought is a cheap laser without an IR filter it probably means that it isnt actually shining 50mw of green light. |

| im not saying it will, im saying you wont be able to tell if its hitting your eye or not. the invisible light it gives out can bounce just like the visible light. If that happens long enough then you will probably suffer some eye damage. |
