Single Vision Spectacle Lens
Single vision lens with power for correcting distance refraction.
|
Multiple-Segment Spectacle Lens
A multifocal spectacle lens that corrects distance refraction and provides myopic defocus at the same time.
Multiple-Segment spectacle lens: A multifocal spectacle lens that corrects distance refraction and provides myopic defocus images simultaneously. The myopic defocus aims at slowing down myopia progression.
