Do Laser Levels Damage the Eyes?
The simple answer to this question is Yes! If you expose your eyes to laser levels for a few seconds, it can create issues with them. As a matter of fact, exposing your eyes to lasers from the laser level for a quarter of a second can lead to some form of damage.
The higher the category or class of the laser level, the greater your risk of injuries when you expose your eyes to the laser. For instance, class 3 lasers can create retinal burns or cataracts. Make sure you avoid direct eye contact with the laser or wear a recommended laser screen when using the device.
How Often Should I Calibrate my Laser Level?
If you use your laser level almost every day, you should try as much as possible to calibrate it once or twice every 6 months. Even the best laser level for carpenters or builders will require regular calibration to maintain its accuracy. If you use your laser level once or twice a week, then you should calibrate it at least once every 12 to 24 months. Please read more reviews of the best laser level for carpenters at LaserLevelHub

Can I check my Laser Level Calibration Myself?
Fortunately, most laser levels come with a manual on how to check laser level calibration. Generally, you should place the level at up to 10 meters from the wall, then activate the laser and evaluate laser lines to see if they are within acceptable manufacturer specifications and tolerance levels. Turn the laser level on a tripod mount or flat surface at 180 degrees and evaluate the lines again. If you are unsure, please take the laser to an accredited service center for proper calibration checks.
What is the Difference Between Green and Red Laser?
Line laser tools for construction normally rely on a red or green laser to carry out construction jobs. In the color spectrum, the human eye will peak at the almost same length as the green color, and given the fact that both red and green laser light has 1Mw power output, the Green laser light will show up almost 30 times brighter than the red laser light.
The green light will also scatter more than the red light, and that means the green beam will travel more distances than the red laser. For these reasons, one can conclude that green lasers are more visible and brighter at long distances than red lasers. You should also keep in mind that green laser levels are usually more expensive than red laser levels. Please check reviews of
