You guys obviously either don't have astigmatism or prism error, or read only very large print. The cheap reading glasses give me a grand headache after only a few minutes, and I'd need a different pair to get a headache with my computer monitor. My "$100" reading glasses are actually bifocal lenses in my distance glasses; they work perfectly, but require that I hold the book at about 12 inches. I need my computer lenses for reading at a more comfortable distance, but that doesn't work for very small print. Naturally I could continue what I do now, which is to keep the two kinds of glasses and constantly change between them, but clearly this Trufocal system would be much more comfortable and easy for me to use. For those who might respond that progressive lenses work well, I can only note that the "sweet spot" for focus at any distance is much narrower than either bifocals or reading glasses, and this requires that I turn my head to scan across the book or computer screen - again, tiring.
Your good nature will bring you unbounded happiness.
