Which of the following is an example of an optical device?

The main idea is identifying tools that actually modify light or use lenses to change how we see something. Magnifiers fit this because they use a lens to bend light and enlarge the image, creating a bigger, clearer view of details for someone with low vision. This is an optical action—the light is being manipulated to improve vision. The other options don’t use light in that way. A device that displays captions doesn’t change the light entering the eye or enlarge the image; it simply presents information. Software that converts text to braille operates digitally and tactilely, not through optical light. A white cane helps with orientation and safety by sensing obstacles through touch and vibration, not by altering vision with lenses or light.
