The lens is not worn during the day. 1 Addressing axial elongation helps to reduce the risk of myopia-related vision complications later in life, including irreversible vision loss. Contact lens and eyeglass lens powers are expressed in diopters (D). Standard single vision correction has been shown to cause peripheral light rays to focus behind the retina, which encourages eye growth and increased myopia. Roughly 80% of what children learn is visual. For example, an optometrist or eye doctor may suggest a soft lens with lesser evidence for myopia control if it fits better and/or provides better vision correction than a soft lens with predicted higher myopia control efficacy.
