I bought this computer screen magnifier for my father for Christmas, but unfortunately, he will not use it. Kantek LCD Magnifier, 19 inch Wide. Enlarges character size by more than double. Full screen magnification for comfortable viewing. High quality Fresnel lense for a crisp, sharp and distortion-free image. Adjustable magnification. Reduces glare. Elegant, light weight design. Quick and easy instllation - no assembly required. It fits easily over the top of the computer screen and greatly magnifies screen contents, but my father prefers using his magnifying glass. I bought it on Amazon and paid $150. Will sell for $50.
