Why I Won’t Switch to Hubble: No Silicone Hydrogel Contact Lenses

5558708237_cff4643b6f_b

I’ve been using Acuvue Oasys for years now. When they first came out, every eye doctor I had told me they were the best. They are both disposable and extended-wear, so can be worn for 24 hours and replaced every 2 weeks. They are made from silicone hydrogel, which is considered superior to regular hydrogel lenses for maximizing oxygen to the eye.

So when I first heard about Hubble’s offer for a free box of contact lenses, the first thing I wondered is, “Yeah, but I can I get my brand of lenses?”

The answer is no. Hubble instead focuses on users who change their lenses daily.

Here’s a medical opinion on Hubble lenses from an optometrist at Yin Eye Care:

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.

According to CLspectrum.com the dt/k of my lenses, Acuvue Oasys (Senofilcon A) is 147, surpassed only by the Air Optix’s Night and Day (Lotrafilcon A) with a dt/k of 175.

Price Comparison

So Hubble advertises $30 for 60 lenses. Only a $1 a day sounds like a pretty good deal right? Well, that’s $365 a year if you wear them every day.

I get my lenses on lens.com which slightly undercuts buying directly from my optometrist’s office.

My eye doctor told me because I take my 24-hour lenses out for 12 hours at night, I can actually wear them up to a month without throwing them out.

12 Acuvue Oaysis Contacts are: $41.99

I have astigmatism in my right eye, so 12 Acuvue Oasys Contacts for Astigmatism are:  $66.40

I get a year’s worth of the one of the best contacts on the market for $108.39 plus taxes and shipping. Even if I wore them 24 hours and doubled the cost, I could still get them at a fraction of what Hubble charges.

Consider your eye health and check the price of your eye doctor’s recommended contacts if you’re thinking of switching to Hubble.
