Rough Ophthalmic Lens Blank

Rough ophthalmic lens blanks are semi-finished lenses used in the production of prescription eyeglasses. These blanks are typically made from high-quality optical materials such as glass or plastic. They come in various shapes and sizes to accommodate different lens prescriptions and frame styles.

Ophthalmic lens blanks are called "rough" because they have not yet been shaped or polished to the final prescription. They are essentially pre-formed lenses that still require additional processing to achieve the desired optical properties.

These lens blanks are an essential component in the manufacturing process of prescription eyeglasses. Opticians and optical laboratories use these blanks to cut, shape, and polish the lenses according to the specific prescription provided by an eye care professional.

In the supply class Ophthalmic Instruments, Equipment, and Supplies, rough ophthalmic lens blanks are categorized as a necessary component for producing custom-made eyeglasses. They fall under the broader supply group of Medical, Dental, and Veterinary Equipment and Supplies, as they are used in the field of ophthalmology and vision care.

Please note that the specific details and availability of rough ophthalmic lens blanks may vary depending on the supplier and the country in which you are located.
