the magnification of fine. but the temples are not very secure to theframe. i ordered 2 sets of these and at least three pair have already been throw out bc the temples fell off (tried tightening the screws but to no avail).
it took me a while to figure it out because they look like several other pairs i have, but at least two pair out of this set give me headaches as the lenses seem to be ground to slightly different magnifications.
the magnification is inconsistent throughout lens...images and words bend unless you look through the exact same spot. but then again, this is what you expect from mass produced chinese plastic. i will be throwing these in the trash. better off going to walmart or walgreens and trying on single pairs.
the frames are well-made and comfortable. magnification is good, but is very limited to a narrow field in the center of view. any situation where you need to look side-to-side/up-down without moving your head (e.g, shaving, reading wide documents, etc.) is impossible due to lens imperfections.
i am happy with the product overall. or i would not have ordered them for a second time. but i have a problem with the advertisement that twice let me order a +5 magnification . the second time i received five pairs of 2.5 magnification.the first time could have been an oversight. the second time i am seeing a pattern of sending the wrong strength of magnification .i'm disappointed because they are very prompt in the shipping time. i received them the next day.
only issue is the power rating may not be the same as other brands. seems the magnification power has no regulations and you have to try several different power strengths to get some that give you the best vision.
