Abstract: The present invention is a magnified screen cover and protector for electronic devices. The invention comprises a magnified surface layer with a top protective layer and a bottom adhesive layer. The invention magnifies the screen of an electronic device with diopter and/or magnification power ranges so that the user may comfortably use the electronic device without the aid of wearing prescription eyewear, contact lenses, reading glasses or other visual aids. The touch screen sensitivity and functionality of the electronic device is unaffected by the magnified screen cover protector, so usability of the electronic devices touch and sensitivity functions are not compromised. The present inventions additional benefit is protecting the glass and/or plastic surface of an electronic devices main viewing screen from scarring, shattering, debris and breakage.
