Is 20-70 vision considered bad?

No. Not really. "Normal" vision is around 20/20 or 20/30. Having 20/60 means that you need to be 20 feet away from an object rather than a "normal" person who can see that object at 60 feet. At 20/60 you should still be able to function with everyday life and only need glasses to drive or to read a blackboard at school. 20/60 is only a mild impairment. 20/30 to 20/60 is considered mild vision loss, or near-normal vision 20/70 to 20/160 is considered moderate visual impairment, or moderate low vision 20/200 to 20/400 is considered severe visual impairment, or severe low vision 20/500 to 20/1,000 is considered profound visual impairment, or profound low vision less than 20/1,000 is considered near-total visual impairment, or near total blindness

Can you be an electrician if im colour blind?

I don't see why not. The work of an electrician does not require 20/20 vision. The electrician should wear safety glasses during work anyway. The only impairment of vision that would prevent you from being an electrician would be colourblindness and it would have to be severe
