I recommend two types of masks, one for when you will be in safer situations, and one for when you expect there won't be as safe conditions as you'd like. For the latter, I recommend N95 masks. For the former, a triple layer washable fabric mask made with tightly woven cotton with adjustable ties and the surgical mask folds is what I recommend. Both styles of masks should have an adjustable insert at the nose portion to provide for a close fit over the bridge of the nose & below the eyes/cheek bones (zygomatic arch). With proper fit of these types of masks, I can talk and breath without fogging up my glasses. Sometimes a slight re-adjustment of the nose-piece or the tie is required, but that is easily managed with minimal touching of the front of the mask.
The mask should allow for tenting and not be tight to the face. The surgical mask style with two or three folds is better than a mask fitted tightly to the face, because when we talk or yawn or sneeze even, there has to be room for the air movement from your mouth and movement of your chin as you speak without pulling the top of the mask down below your nose, which defeats the purpose of protection.
Not every one prefers ties like I do, but they work best for me. I wear hearing aids, and do not tolerate the behind-the-ear style at all, as my hearing aids become dislodged and come off when removing that kind from behind my ears. Plus often the elastic behind the ears are either too tight or too loose. If you consider a tie style, this is what I do to make wearing mine more convenient:
The only tie I untie when I remove the mask is the bottom tie. I keep the top tie tied all the time (except when washing) because once I find the perfect fit for the top of my head, I keep it tied and just put it on top of my head first when I first put my mask on, adjust it to my face, then tie the bottom behind my neck. When I take the mask off, I untie the tie behind the back of my neck and lift the mask up over my head removing from the top. This is done normally when I get in or out of my car. Then I put the mask over the dashboard of my car where the windshield focuses sunshine right down on the outer surface of the cloth mask until I stop at the next place where I must put the mask back on again.
Ties with adjustable toggles serve the same purpose, but can be uncomfortable in some situations. I don't really know, as I don't have any masks with toggles.
I know some folks wear a head-band with buttons for the behind-the-ear masks, but I have not tried them so cannot speak to how well the fit is in regards to wearing goggles or glasses and preventing fogging.
We need to protect our eyes as well, particularly when in less safe conditions, therefore I also recommend safety sunglasses or clear glasses if you don't need to wear eyeglasses at all times, the wrap-around style that provides the greatest protection. Or better yet, if you can find one and tolerate it, a face shield that you can wear over your glasses, for those crowded conditions where others don't always adhere to social distancing. My granddaughter wore one over her mask while at the airport and on the airplane. I bought some at Farm & Fleet for a mere $4.00 each. I've seen them in some mainstream stores as well, as well as on Amazon. It doesn't have to be expensive.
For someone who is able to purchase and maintain a constant supply of replaceable filters and will be in situations where social distancing is less reliable or in confined spaces for lengthy periods, that may be a better choice than a surgical style mask or N95 masks, which may be hard to find in some areas.
