I have to make a survey about alarms. Like, ask questions about alarms eg using what, where, how, who, why, when.Does anyone know any questions i could ask for my survey?
i admire the way people jokes with this of the smoke alarm,(Sept-a million) ninety % of the time this occurs, you will desire to placed new battery in it, (spet-2) confident that is ture you will desire to vacum it , to get the dirt off that when it acumulat it makes the smoke alarm artwork hader to ditect, all that is air area is block, and while it overs warmth it makes some loud beeps, some situations its battery and it sluggish its sparkling up time indicater, don't be scare, in basic terms placed the baterry on and that's all. solid success,
Iridium is the material that is used in the coating itself. It's what gives the lenses the reflective color and coating. This has a minimal glare reducing effect. Anti-reflective coating is a generic name for a process used by many manufcaturers when they place and anti-glare material onto a lens. You can get this same material on prescription glasses. This has a minimal glare reducing effect. Ionized coatings is a marketing term used to differentiate Dragon from Oakley's Iridium. It's essentially the same process as particles needs to be ionized to stick to the lens. Again, minimal glare reducing effects. The coatings help some, but for high glare applications, you need to look at a polarized lens. That being said, there are DIFFERENCES in the base optical clarity of all of these lenses. Oakley lenses have been shown to be more distortion free (optically correct) than the other two brands. Oakley lenses have also been shown to be more impact resistant. So all other things being equal, the Oakley lens is superior. This extends to when you look at polarized lenses, as well. Oakley is the only company that does NOT use the Sandwhich method to make polarized lenses. The sandwhich method is where two halves a lens have a polarization film glued in between them. This causes tremendous amounts of distortion and leads to eye fatigue and headaches. Oakley's polarization is built in to the lens as the lens is being manufactured (this is a patented process used by Oakley) and not the sandwhich method. This makes a polarized lens that has less distortion than any other on the market (outside of glass- which isn't safe to wear). HTH D
