A retinoscope is especially useful … WebObjects that reflect less than a specified amount of light are as follows: (1) Objects with extremely low reflectance and objects that are darker than black paper. (2) Objects like mirrors that return virtually all light back to the Emitter. (3) Uneven, glossy surfaces that reflect a lot of light but disperse the light in random directions.
