The two pairs I received have distortions in the lenses
The glasses arrived a day early and were well packaged.  They came with two slide in cases and one cleaning cloth that was a nice surprise.  The glasses are sturdy and nice looking.  They do seem to filter the blue light without changing the other colors on my computer screen.  They do have spring frames.  They are very tight to start with, but do ease up as you wear them.<br /><br />The unfortunate reality is that there is a distortion for both pairs of glasses.  I do not see clearly with these readers as I do with other readers I have had.  The magnification is correct, but I have a hard time focusing.  I don't know if this is just a problem with the two pairs I received or if this is a result of the blue blocking feature or perhaps the way the magnification is in the lenses.  My low rating is due to the fact that I cannot see clearly with these which is a requirement for reading glasses.
