How Are Contact Lenses Made? Breaking Down the Manufacturing Process
The creation of contact lenses is a fascinating blend of science and precision engineering. These modern marvels are some of the most common medical devices millions of people interact with and use on a daily basis, without knowing the full story of how they came to be. This article delves into the meticulous process behind manufacturing these delicate yet vital pieces of eye care technology, and provides a little more background on Hubble’s quality line of contact lens products.
The Initial Stages: Material Selection and Molding
The journey of a contact lens begins with selecting the right material. Modern lenses are typically made from hydrogel or silicone hydrogel, materials chosen for their comfort and oxygen permeability. The molding process is next, where this material is precision-shaped to create the lens. This step involves intricate molds that define the lens's curvature, thickness, and overall design, tailored to various vision correction requirements.
Hydration and Shaping
Post-molding, the contact lenses undergo a hydration process. Here, they absorb water, transforming from a hard state to a soft and pliable form. This stage is crucial for comfort and wearability. The lenses are then further shaped and refined to match specific prescriptions, ensuring each lens provides the correct vision correction.
Polishing and Quality Control
After shaping, lenses are polished to create a smooth surface, enhancing comfort for the wearer. Quality control is paramount in this process. Each lens is rigorously inspected for defects, clarity, and prescription accuracy. Advanced technology is employed to ensure that every lens meets strict standards of quality and safety.
What Materials Are Used in Contact Lenses?
Contact lenses are primarily made from hydrogel or silicone hydrogel, selected for their comfort and breathability.
How Long Does It Take to Make a Contact Lens?
The manufacturing process, from start to finish, can take several hours, depending on the complexity and type of lens being produced.
How are Hubble Contacts Made?
All of our lenses are manufactured by our partner, St. Shine, in their state-of-the-art facility in Taipei, Taiwan. Hubble lenses have been FDA approved for sale in the US for over a decade and a whopping 400,000,000 prescription lenses have been sold to date!
What are Hubble Contacts Made Of?
Over the years, we’ve introduced a wide range of daily disposable prescription contact lenses to meet the needs of any and all wearers!
The ones that started it all, Classic by Hubble Lenses are made with Methafilcon A Hydrogel material and feature 55% water content and UV protection.
Hydro by Hubble contacts are Hioxifilcon A lenses, an enhanced moisture-retaining material, designed for all-day hydration and comfort.
Finally, SkyHy by Hubble contacts are our most breathable pair of lenses yet. Made with Olifilcon B (a silicone hydrogel material), their flexible construction molds to the curve of the eye and keeps moisture locked in.
Final Packaging and Distribution
Once the lenses pass quality control, they are sterilized and prepared for packaging. The packaging process is done in a sterile environment to prevent contamination. Finally, the lenses are ready for distribution to retailers and eye care professionals, making their way to consumers worldwide.
Technological Innovations in Contact Lens Manufacturing
Recent advancements in manufacturing technology have further refined the production of contact lenses. Innovations include automated systems for greater precision, new materials for enhanced comfort, and more environmentally sustainable manufacturing practices.
