The truth about Hubble contacts
While it’s tempting to switch to online contact lenses that seemingly cost less, you may actually be overpaying for a lower-quality product. So here’s the lowdown on what we recommend and why.
Contact lenses are MEDICAL DEVICES that not only help you see better but they sit on your cornea, the clear tissue at the front of your eye. When fitting you with contact lenses, Dr. Yin considers not only what focusing power you need (converted and not always the same as your glasses power) but also the size, shape and curvature of your eyes, your tear film, your allergies and what lens material will give you the best health as well as comfort.
Different contact lens materials let different amount of oxygen through the plastic to the front of your eye. The oxygen transmissibility (Dk/t) of the lens material affects the long-term health of your cornea and your comfort. Hubble contacts are made out of a 20+ year-old lens material called methafilcon A, which has a Dk/t of 18.8. Research shows that a Dk/t of 24 is necessary to maintain cornea health and avoid swelling. Dr. Yin recommends much newer lens materials that let in a higher amount of oxygen to prevent problems with discomfort, red eyes, blood vessel growth into the normally clear cornea and unexpected changes in prescription. Current contact lenses have Dk/t measuring over 80 which allow 4+ times more oxygen to your cornea than older lens materials.
So when it comes to the health of your eyes, why settle for an older lens material when for a few dollars more you can have a newer, healthier and more comfortable lens?
