A handheld or hands-free device combines magnification with illumination to enhance the readability of printed materials. Typically, these devices employ a Fresnel lens to enlarge text and images while integrated LEDs provide focused light directly onto the reading surface. This combination addresses the challenges posed by small print and inadequate lighting conditions, making reading more comfortable and accessible.
Enhanced readability contributes significantly to improved reading comprehension and reduces eye strain, particularly for individuals with low vision or age-related macular degeneration. By mitigating the physical strain associated with deciphering small print in dim light, these devices promote sustained reading engagement and offer a higher quality reading experience. Historically, simple magnifying glasses were used, but the incorporation of light sources represents a significant advancement in assistive reading technology.
