help Foster Grant Blue Light Readers FAQ
Do Foster Grant Blue Light Readers magnify text as well as filter blue light?
Yes, they are reading glasses, so their main optical function is magnification for close work. The blue-light feature comes from the lens treatment or material, but it does not replace the need to choose the correct reading strength.
Are Foster Grant Blue Light Readers prescription glasses?
Most Foster Grant readers are non-prescription over-the-counter glasses in set magnification strengths. They are not a substitute for prescription lenses when someone has different correction needs between the two eyes or an eye condition.
Can I use Foster Grant Blue Light Readers for computer work?
They can help with close text on screens if the reader strength and working distance are suitable. Computer distance is often farther than book-reading distance, so a basic reader may feel too strong or require you to sit unusually close.
Do blue-light readers prevent eye damage from screens?
They may reduce some glare or make screen use feel more comfortable, but they should not be described as preventing eye disease. Regular breaks, comfortable brightness, and blinking are also important during long screen sessions.
