Brother SAML Magnifying Dual Lens Attachment

I am vision impaired and this works great

First, I received this as a part of a machine purchase, so I didn't really order it. I wasn't going to even use it, but then I thought I'd try it. It really does magnify the needle area well. I think if my vision deteriorates more with age, this might be handy when sewing seams and other work. I do like they way the yarn guides are incorporated for using while couching. I haven't tried couching yet, but I will!
