My brother recently bought for our children two green laser pens from "DragonLaser". They were both the Viper Series "125mW". Our family are big Star Wars fans and our kids loved to pretend to be Luke Skywalker and Darth Vader and duel with the laser pens. Recently they have been complaining of strange eye issues though. One says he sees black dots in his vision and the other says he has a 'blob in his eyes'. I have set up an appointment for them at an optometrist. Could it be reasonable to think that the laser pen could be the cause of this?
