Contact lenses offer both functional and cosmetic solutions for vision correction, demanding precise fitting and in-depth ocular knowledge. This book explores the scientific principles and practical techniques involved in contact lens prescribing, from corneal measurements to lens material selection. It covers soft, rigid gas-permeable, scleral, and specialty lenses for conditions like keratoconus and post-surgical eyes. Topics include tear film assessment, lens care systems, complication management, and patient education. With a blend of clinical guidelines and case examples, the text prepares practitioners to deliver safe, customized contact lens care across varied patient needs.
Ivy Chen is a clinical optometrist and researcher with a strong focus on contact lens technology and fitting practices. She has extensive experience in managing patients with refractive errors, keratoconus, and dry eye conditions using soft, rigid, and specialty lenses. Ivy also teaches contact lens physiology and care protocols in academic settings across East Asia. Her research investigates oxygen permeability, lens materials, and patient adherence, contributing to safer and more effective lens wear. She emphasizes precision, comfort, and corneal health in her approach to lens prescribing.
