Generally, each lens materials can block some light from passing through the lens. This light reflects back from the lens surface, causing distractions and reducing the clarity of night vision. Conventional glass or plastic lenses or polycarbonate lens can reflect about 8 percent of light that otherwise would reach the eye. High-index lenses reflect up to 50 percent more light than conventional glass or plastic lenses/polycarbonate lens.
Which eyeglass lense has more reflection, polycarbonate or hi index?
