why did my smoke detector go off last night 4am and there was no smoke anybody know why?

Answer:

Its in the wrong place anyway the steam is causing it to short circut the alarm.It should be in a hallway or kitchen or bedroom.
$600 is too much. I might expect $400 for 1.67 hi index material and a premium Anti Reflective coat with a roll and polish. If you also wanted to get transitions, the price may go up to around $525 but that is about the top price that I would charge for lenses. I would shop around. If you want, email me and tell me exactly what type of lens and what add ons they want to give you and I'll give you a fair evaluation of what the price should be.
