What is up with Hubble Contact Lenses

Beware Hubble Contact Lenses Online

Hubble Contact Lenses Are a Concern to Most Eye Doctors

Jennifer Ortakales Oct 1, 2019

The following is an excerpted article from the website If you wish to read the entire article on the original web page, please click here.

I’ve used buzzy contacts subscription startup Hubble for almost 3 years, but never thought twice about it until I learned why some doctors hate the brand so much…

I’ve been wearing Hubble contacts for about three years and generally had a good experience. But many eye doctors don’t like Hubble. I talked to four doctors, none of whom recommend Hubble. They said that the lens material is outdated and the company risks selling incorrect contacts to patients.

The Federal Trade Commission (FTC) has received over 100 complaints about Hubble that show similar concerns. Many mentioned customers who received Hubble lenses without their doctors’ knowledge.

I also talked to seven customers, most of whom stopped using Hubble because they found the contacts to be uncomfortable. Hubble says eye doctors don’t like it because the startup threatens their business. And the company says there’s no evidence that its contacts are worse than other options.

When I visited Warby Parker a few months ago, it’d been two and a half years since my last eye exam. I knew my new prescription would be significantly different from the contacts I’d been wearing. But I didn’t know I might have been wearing the wrong lenses the whole time. During my appointment, the optometrist asked to see a package of my current contacts to write my new prescription. I pulled the little blue packages out of my bag and she asked, “Are those Hubble?” She seemed alarmed.

I told her that Hubble dailies were the only lenses I’ve worn that don’t dry out my eyes by the afternoon. I also liked the convenience of getting them shipped to my apartment.

She seemed surprised. She told me she never recommends Hubble to her patients, calling the lenses outdated, and criticizing the company’s verification process. Still, she reluctantly wrote me the prescription.

I sent Hubble my updated prescription, but the optometrists’ concerns were still bothering me. I’d never had any eye problems, but maybe there was something sketchy about Hubble. So I decided to do some research and seek second opinions.

‘Contact lenses are not one-size-fits-all’

Hubble, founded in 2016, ships contact lenses to customers for about $1 a day. The company has raised $70 million from investors, and is valued at about $246 million, according to PitchBook. Online, I found doctors criticizing Hubble’s practices and technology. Dr. Ryan Corte of Northlake Eye in Charlotte, North Carolina was one of them. He tested Hubble’s free trial in February 2018, but said he couldn’t wear the contacts for more than a day.

Corte’s main points were almost identical to my optometrist’s qualms — outdated material, questionable verification method, and concerns for patient safety. But his review applauded Hubble’s cofounders for their business acumen. “They took an old material and built a brand behind a fun name and sexy marketing campaign,” he wrote.

Corte is concerned that Hubble is taking shortcuts that don’t place patients’ overall eye health at the forefront. “If your vision in your contact lens is off,” he told me on the phone, “that can lead to eye strain, headaches, fatigue, decreased quality of life overall for people.”

And it’s not just Corte. The American Optometric Association (AOA) has criticized Hubble for substituting specific prescriptions for generic lenses that don’t account for conditions like astigmatism, dry eyes, or size of the cornea.

“Contact lenses are not one-size-fits-all,” said Dr. Barbara Horn, president of the AOA, “It appears that Hubble believes that their lens can do that and it definitely can’t.”

Reports in publications like the New York Times and Quartz have criticized the way that Hubble verifies prescriptions, as well as the older material it uses to make its lenses. Hubble uses methafilcon A, a material that’s been used since 1986.

There’s been plenty of debate over whether the older material that Hubble uses for its lenses is truly inferior to newer options.

In a statement to Business Insider, Hubble said that there’s no evidence that newer lenses, which can let more oxygen reach the eye, are more comfortable or perform better.

Here’s Hubble’s statement:

“Studies have shown that, for daily disposable contact lenses, the increased oxygen permeability of newer silicone hydrogel materials has not meaningfully improved contact lens performance or comfort. In fact, a recent study of daily disposable contact lenses found ‘no clinically significant differences’ between contact lenses that, like Hubble, are made of hydrogel materials and those that are made of more expensive silicone hydrogel materials. The study also concluded that contact lens material choice is a matter of preference.”

But I wanted to know if there are any serious or long-term risks to using an outdated lens material, or if it is more of a personal preference, like choosing between the latest iPhone and a two-year-old model that works just fine.

I talked to four doctors, none of whom recommend Hubble. They said that the lens material is outdated and the company risks selling incorrect contacts to patients.

I also reviewed more than 100 complaints about Hubble sent to the Federal Trade Commission (FTC). The complaints echoed the same concerns and mention customers who received Hubble lenses without their doctors’ knowledge.

Finally, I talked to seven customers, most of whom stopped using Hubble because they found the contacts to be uncomfortable.

Of the four doctors I talked to, none said they’d recommend Hubble to their patients.

Dr. Allen Wegener of Richards and Wegener Optometrists in Liberty, Missouri, said he doesn’t prescribe Hubble, because the technology is old. “People don’t go out and buy old flip phones,” he said.

When Corte, the eye doctor in North Carolina, fits his patients for contacts, he makes sure the lens centers well on their eye, has the right curvature, the right diameter, the right power, and that the patient is comfortable. “If the fit is poor, it can slide around and just lead to discomfort,” said Corte.

But there can be serious issues if a patient switches to another lens that their doctor never fit them in. If the lens is too tight, said Corte, it can lead to complications from a lack of oxygen getting through from the tear film to the cornea. Most doctors I talked to are concerned that Hubble’s lenses don’t allow enough oxygen to the eyes.

And oxygen, I found out, is essential to eye health. The retina is one of the highest oxygen-consuming tissues of the human body. For the 13 years I’ve been wearing contacts, I never knew my eyes “breathe.” Every contact has an oxygen permeability (OP) rating, or transmissibility level (Dk). The higher the number, the more oxygen can get to your eyes. Oxygen not only makes the contact comfortable on the eye with each wear, it also helps keep the eye healthy over time.

Dr. Katie Miller of Envision Eye Care in Rehoboth Beach, Delaware said she won’t prescribe Hubble’s lenses because the material doesn’t let enough oxygen reach the eye. Doctors have another major concern. Many claim they don’t receive any of the prescription verification requests that Hubble sends out.

To verify a prescription, Hubble calls the customer’s doctor with an automated message. According to the FTC’s “Contact Lens Rule,” sellers must give doctors eight business hours to respond to a prescription authorization. If sellers like Hubble don’t receive a response in that eight-hour window, they are free to fulfill the prescription.

The FTC has received 109 complaints about Hubble and its practices. The most common complaints are that doctors are either not given a chance to answer “robotic” and “incomprehensible” voicemails from Hubble or that they do not authorize the verification, yet they later find out their patients received Hubble lenses anyway.

In a statement, Hubble said it uses automated messages, “in part to prevent verification agents from inadvertently omitting information that is required to be conveyed to eye care providers by the Contact Lens Rule.”

Horn, the AOA president, said Hubble’s automated calls are difficult to understand, and that some doctors can’t hear the patient’s name or birthdate. The AOA is working on a bill that would prohibit automated calls, she said.

Hubble provided the following statement to Business Insider:

“The AOA has been trying to prevent consumers from buying contact lenses online for two decades, and this is just another chapter in that story. Congress will understand that the AOA’s purpose is to enrich their membership at the expense of their patients.”
According to an AOA statement sent to the FTC, the AOA has received 176 physician complaints regarding verification calls since 2017, 58% of which were related to Hubble.

The doctors I spoke to said they’ve never received communication from Hubble to verify patients’ prescriptions.

Dr. Jason Kaminski of Vision Source Longmont in Longmont, Colorado filed a complaint with the FTC. He declined to comment on the complaint, but he said that in one instance, Hubble substituted the specific lens and material he’d prescribed for a patient. He said he’s never authorized Hubble lenses, yet his patient received them anyway.

Horn had a similar experience. She’d fitted a patient with a special lens for astigmatism. The patient came back to Horn’s office a few weeks later, upset because her vision was blurry.

“She’d given the prescription [to Hubble] and the lenses given to her by Hubble weren’t anywhere close to her prescription,” Horn said.

While some Hubble customers can get expired prescriptions fulfilled, others have experienced an interruption in service when their prescriptions aren’t verified.

I hadn’t been to the eye doctor since August 2016, but I received Hubble contacts for almost a year after my prescription expired in 2018. Hubble told me it re-verified my prescription in December 2018, although my doctor’s office told me it had no record of that authorization.

The customers I talked to tried Hubble because they thought it would be more convenient or cheaper than their previous brand. But for many, the convenience faded away once they wore the contacts. Every contact has an oxygen permeability (OP) rating, or transmissibility level (Dk). The higher the number, the more oxygen can get to your eyes. Hollis Johnson/Business Insider
Wade Michael, a brand strategist, said he found Hubble’s marketing attractive and sleek, comparing it to Harry’s and Casper. “It just happened that the quality, I think, didn’t match the actual product at the end of the day.”

Michael could comfortably wear his previous Acuvue Oasys bi-weekly lenses from 6 am to 11 pm, but couldn’t wear the Hubble dailies for nearly as long.

“I noticed that I was trying to put them in my eye as late as possible in the morning before I left for work,” said Michael. “By like five or six at night they were super dried out.”

Michael wore Hubble lenses for about a year and a half before switching.

His new doctor prescribed One Day Acuvue Moist and Michael said it’s a “night-and-day” difference. “Holding my lenses now, it feels like water almost. You can tell that they’re super supple and really, really well hydrated, which compared to the Hubbles, it’s a really stark contrast.”

Christina Feller stopped using Hubble contacts after one became stuck in her eye or damaged it.

When Feller first signed up for Hubble, she said she thought they would be easier and cheaper. “That was before I knew that they were dailies,” said Feller.

‘There’s no way I’m putting these back in my eye”.  Her previous lenses lasted all day, from about 9 am until 10 pm. But she said Hubble’s lenses only lasted until about 3 pm. “I would always have to take them out because they would dry up my eye and they would feel uncomfortable,” said Feller. She doused them in saline solution to make them more bearable.

When she arrived home from a long drive, she said she couldn’t get the right lens out and her eye became red and irritated. “It feels horrible. It feels like a contact is in there. So I’m like freaking out at this point.” By 11 pm, she decided she had to sleep with the contact still in her eye. She went to the eye doctor the next day, where two doctors examined her eye but couldn’t find the contact. The doctors told her the contact must have fallen out and scratched her eye.

Feller threw out the rest of her Hubble lenses. “There’s no way I’m putting these back in my eye after that,” she said.

For three months, Eric Vandegrift noticed his Hubble contacts getting drier. Then he got an abrasion on his eye. “They just got continually worse for my eyes,” said Vandegrift. He wore them regularly every day. “I’d actually take them out before the day was done because they were dry.” One night he’d had some trouble taking out his contact, but didn’t notice until morning that there was an abrasion on his right eye. He went to a music festival with partially-blurred vision and mentioned Hubble in a tweet.

His doctor gave him medication for the abrasion and prescribed Acuvue contacts.

“It’s partially on me,” said Vandegrift. “It’s on the customer to know when a product is cheap.” He said the whole experience has made him take his health more seriously. “I’m not painting them as a bad company, just their product is garbage,” he said.

My own experience with Hubble contacts has been fine, but after almost three years using them, I’d like to try a brand that doctors trust. Most of the customers I spoke to said Hubble contacts got too dry to wear for a full day. I’ve generally had a pleasant few years using Hubble, with few negative side-effects. I don’t wear them every day, but typically switch between glasses and contacts throughout the week. I’ll admit that lately my Hubble boxes have been piling up, as I’ve been wearing glasses more often than usual since starting this article.

Sometimes my Hubble contacts get dry, particularly if I fall asleep on the train. They feel like sandpaper after a 20-30 minute doze and I can barely keep my eyes open for the five minutes it takes to regain moisture. Occasionally, I’ve experienced weird sensations — feeling the lens on my eye, bits of light or color passing in my vision, some random stinging and watery eyes. Not to mention, I do have slight astigmatism that Hubble lenses don’t correct.

Dr. Horn says that if a contact lens doesn’t feel perfect within minutes, it should be reevaluated.

“If a lens isn’t feeling right on your eye, that is telling you something,” said Horn. “It isn’t going to be damaging to every patient, but with healthier options available, you want the healthiest option that you can get.”

For now, I’ll use up the five boxes of Hubble contacts I have left, while wearing my glasses most of the time. But I’d like to try a new brand to test whether it could make a difference, and possibly get me back to wearing contacts almost every day.

NBA Great Curry Credits Contact Lenses

Stephen Curry contact lenses help him win

Stephen Curry snaps out of his slump with contacts!

Golden State Warriors star Stephen Curry says contact lenses are the reason he snapped out of his post- All-Star shooting slump.

(This is a reprint of the original article published at


“I started wearing contacts,” Curry told Marcus Thompson II of The Athletic. “No, I’m serious. It’s like the whole world has opened up.” The sharpshooter says he’s always had issues with his eyes, but he was able to overcome those difficulties.

“I had gotten so used to squinting for so long,” Curry added. “It was just normal.”

But because Curry suffers from a degenerative eye disease, it’s possible his vision has worsened over the years. Here’s more from Thompson on Curry’s eye condition, which is called Keratoconus:


“Technically, it’s an eye disease in which the cornea, normally a circle, progressively thins and takes on a cone shape.  This distortion has given Curry what is known as an astigmatism, which is a type of error in the way the light bends when entering the eye. It doesn’t distribute the light equally to the retina and leads to blurred or distorted vision. It’s a genetic condition Curry was probably born with, though scientists don’t know how it is acquired.”


The 31-year-old is shooting 48.7 percent from 3-point since mid-March and has hit five-plus 3-pointers in nine straight games. Somehow, it seems Curry — arguably the greatest shooter in NBA history — will be even better at shooting now that his eyesight is corrected.

The Warriors will need Curry’s vision to remain clear as they look to win their third-straight NBA championship this summer.

Top 10 Best Foods For Better Vision Health

Health for your eyes with Kale

Your Eyes Deserve Your Best Health!

The definitive, final, ultimate list of which foods are best for preserving your eyes and your vision health.

(ok, maybe not the ultimate health list, but we like giving this blog post a bit of hype – tongue in cheek)

We have crunched the numbers. We have done the “health” math. We have done our homework. Here is our official TOP 10 FOODS TO EAT FOR BEST VISION HEALTH. It is not an exhaustive list by any means, but these are the top 10 foods that, in our view, will do the MOST for helping you maintain excellent eyes, excellent vision well into your years.

It is recommended by some that one should have at least 4 of these foods in your diet regularly at a minimum. If you are consuming 8 or more of these, you get an A+!

Here are the Top 10 foods you should have in your diet for better vision:

#10 Raw Red Peppers

Bell peppers give you the most vitamin C per calorie. Did you catch that? Those things as light as balloons pack quite a punch. Vitamin C is good for the blood vessels in your eyes, and science suggests it could lower your risk of getting cataracts. It’s found in many vegetables and fruits, including bok choy, cauliflower, papayas, and strawberries. Now, if you cook this stuff you WILL decrease its health impacts… A LOT!. So go raw man! Go raw!

#9 Legumes

Lentils, Kidney Beans, and Black-Eye Peas are all giving you bioflavonoids and zinc — and can help protect the retina and lower the risk for developing macular degeneration and cataracts.

#8 Nuts

You have a lot of freedom in this category: pistachios, almonds, walnuts, even peanuts, all are rich in omega-3 fatty acids and vitamin E that boost your eye health.

#7 Oranges or Grapefruit

Vitamin C can boost immunity, which is great. But there is some research to suggest that it also may improve the health the eye tissue itself. The National Eye Institute commented that Vitamin C “may help to regenerate other important antioxidants” in the eyes, such as Vitamin E.

#6 Sweet Potatoes

Orange-colored fruits and vegetables are all high in beta-carotene. This is a form of Vitamin A that helps with night vision, your eyes’ ability to adjust to darkness. One sweet potato also has more than half the vitamin C you need in a day and a little vitamin E.

So you can dig into sweet potatoes, carrots, cantaloupe, mangos, and apricots.

#5 Eggs

Eggs have zinc. Zinc helps your body use the lutein and zeaxanthin from its yolk. Why is this important? Well, it seems the yellow-orange color of these compounds also blocks harmful blue light from damaging your retina. It is all about protective pigment in the macula folks! You say WHAT!? Yeah, that is what we said!

#4 Lean meat and poultry

In moderation, lean beef in your diet can boost your eye health. Beef contains zinc, which helps your body absorb vitamin A and may play a role in reducing risk of advanced age-related macular degeneration. Poultry and pork are also good sources, but so are Oysters. In fact Oysters have more zine per serving than ANY OTHER FOOD. But hey, if you are into Oysters. It’s an acquired taste we are told.

You see, Zinc brings vitamin A from your liver to your retina, where it’s used to make the protective pigment melanin – it’s all about that darn pigment.

#3 Carrots

Carrots are known for helping with good eye health. Again, Vitamin A is at play here along with beta carotene. The surface of the eye is positively impacted by these two buddies, which can prevent eye infections and other serious eye conditions.

#2 Kale or Spinach

Kale and Spinach are big winners in this top 10, but so are collard greens. “Don’t forget them collards” is the saying isn’t it? Well, if not – anyway – don’t forget them. These three are all rich in vitamin C and E and also have the carotenoids lutein and zeaxanthin. These plant-based forms of vitamin A lower your risk of long-term eye diseases, including AMD and cataracts.

We can bet that most of you don’t eat enough of these powerful foods. These are a must in our view.

#1 Fish

And then there was one. The top of the heap, the big hauncho! Well, in our list, it is Fish. We know all about the mercury concerns and they are very, very real (and getting worse). But for now, there is one food that simply gets it done and that is fish. Omega-3s are the key here. Don’t like fish? Then look into Omega-3 supplementation. Your eyes will not only thank you, they will be healthy enough for you to perhaps continue seeing well late into your life.

Well, there you have it. The official TOP 10 FOODS TO EAT FOR BEST VISION HEALTH. We hope you have enjoyed learning a bit along with us! Now our crack research team will go back to shipping out your contact lens products that you keep ordering again and again! Oh – and by the way, thank you for that! Your business means the world to us!


  1. Broccoli
  2. Brussel Sprouts
  3. Squash
  4. Avacadoes
  5. Sunflower Seeds

…there, we didn’t want to go down on record without naming those foods too. Look, if you are eating even a bit of each of these on a semi-regular basis, that is something. Something always most start with something, for from nothing comes nothing. Whoa, did we just write that?

Warmest regards to all of you!
