The whole of the lens is not 2.5 magnification only a small section near the nose bridge, a bit disappointed, thought at last I had found my perfect pair of fishing glasses, going to have to wear them over my current glasses to get the full benefit.
The sunglasses listing is as follows;
' Available with magnification in lower part of lens (lenses are deep enough to keep magnification out of main view when fishing)'.
It sounds like you would require prescription sunglasses lenses. Our sunglasses range have a small magnification area at the bottom of the lens to help with tying knots etc.

The 2X magnification solved my sight problems for tying flies to my tippet and every knot. The quality and price are great.
Give them a try, you won't be disappointed.
Quality of the glasses was next to none!
Exactly as expected!
Delivery was the quickest I’ve ever received something came just two days after I ordered!!
Light and extremely comfortable. As good as glasses 4x their price. Superb for River fishing 5*!
