Great Product for My Needs
The glasses work well for my use. Very comfortable. They seem to be optically correct.  I normally wear trifocal glasses.  I buy &#34;readers&#34; using my distance vision prescription so I can do things like watch television in bed.  I also use them for other distance-only situations where a trifocal interferes with depth perception (e.g. going down a flight of stairs).  I am impressed by the quality of the product.  I can keep one pair on my nightstand, one pair in my handbag and another pair wherever I might need distance vision only.
