Optical properties: The optical properties of ophthalmic lenses encompass their unique characteristics that enable them to accurately refract and focus light, resulting in clear and precise vision.
Mechanical properties: The mechanical properties of ophthalmic lenses encompass their physical attributes, including durability, flexibility, and resistance to impact or breakage, ensuring they can withstand everyday use and potential mishaps.
Electrical properties: Ophthalmic lenses generally do not exhibit significant electrical properties, meaning they do not possess inherent behavior or conductivity in response to electric fields.
Chemical properties: The chemical properties of ophthalmic lenses refer to their ability to resist various chemical substances, such as cleaning agents or solvents, while also exhibiting resistance to scratches, stains, and discoloration caused by environmental factors.
Thermal properties: The thermal properties of ophthalmic lenses concern their response to temperature changes, ensuring they can withstand heat, expand or contract appropriately, and maintain stability under different thermal conditions.
