Maybe I’m just confused because I have monofocal lenses, know my PD and the reliable width for my frames to be comfortable. I can accept I’ve had different experience than the norm. I’ve never had the frame adjustments for eye strain, just comfort. I also have been seeing and buying glasses from the same eye doc for 25 years, so that helps.
With those types of lenses that you were talking about, there’s only one focal point. So therefore, your glasses , the frames , could be a couple of degrees off before even notice anything. With progressive you have many focal points many fields going up and down the lenses. So if they are off even by a little bit.One eye will be looking through one field and one eye looking through another field.
Which means one eye will be focusing at one distance and one eye will be focusing at another distance. That’s some ugly eye strain.
For some people they can handle that. They just concentrate on the one eye or the other eye. But there’s a lot of people who they can’t do that. And that’s where the real problem is at.
But I do understand your lack of knowledge on the subject as a lot of people don’t understand where the real problem is that.
how do you adjust the lenses
It’s a common way of saying adjusting the frames.
