BM-2 Unisex Autozoom Reading Glasses, Reading Magnifying Glasses, Anti-Blue Ray Reading Glasses 0-700

Features of Unisex Autozoom Reading Glasses:

1. Autofocus/Autozoom Technology

   • These glasses claim to adjust magnification automatically based on the distance of the object you're viewing.

   • They may have liquid lenses or flexible frames that adapt to different focal lengths (e.g., for reading, computer use, or intermediate distances).

2. Magnification Range (0-700 or similar)

   • Some brands advertise a wide range (e.g., 0.00 to +7.00 diopters), but true autofocus glasses are rare.

   • Most adjustable readers have a fixed magnification but allow slight focus adjustments.

3. Blue Light Blocking

   • Designed to reduce exposure to harmful blue light from screens (LEDs, computers, phones).

   • Look for lenses that filter at least 30-50% of blue light (wavelengths around 400-450nm).

4. Unisex Design

   • Typically lightweight, with flexible frames that fit most face shapes.

   • Some come with spring hinges for comfort.
