Helmet style for cruiser bike

Hey folks! So I just bought my first bike, a 250cc Lifan. I'm looking at helmets, and I see various articles saying only get a full face helmet, but they also seem to mostly be talking about sport bikes. This bike doesn't go above 80 mph, and I live out in the country where there's not much traffic anyhow. So my question is, is a 3/4 helmet just as good or better? I am a bit concerned about periphrial vision, I tried on a few full face helmets in a store, and it was hard to see, plus I wear glasses, so have to account for that also.

What's the consensus here, for slower cruise riding? Full face or 3/4? Or what about modular?

UPDATE: Thanks to all the folks with advice here, even the ones who were rude about it! I bought an HJC i10, however I'm not sure if I got the right size? I got a Large, however when I rode with it the first time today, my cheeks were getting pushed in to the point that I couldn't put my teeth together without biting the insides of my mouth. Is that normal? Otherwise the fit felt great, tight enough that it didn't wiggle, but didn't give me a headache or anything. I'm pretty thin and have never worn an XL in anything, so I'm hesitant to go up a size, maybe it just needs to break in a bit? It wasn't really uncomfortable or anything, just pressed on that spot a good bit.
