Buy Polarized Contact Lenses

Johnson & Johnson (which owns Acuvue) teamed up with Transitions Optical, the brand that created those color-changing lenses. After more than a decade of development and product testing, they debuted the contacts in the US in March. I tried them out to see how they worked.
These Acuvue contacts have Transitions' \"Light Intelligent Technology\" -- a photochromic additive -- mixed into the soft hydrogel material that creates the lens. When this photochromic additive is exposed to UV light or blue light from screens and lightbulbs, it darkens the lens to block UV radiation and excessive light waves, just like sunglasses do.
The contacts adjust throughout your day to allow a consistent amount of light to reach your eye, whether you're in a dark theater or outside under the sun. When your eyes are exposed to UV light, the lenses take around 45 seconds to fully darken. Once you step inside, they go back to clear in about 90 seconds or less.
Throughout the day, the contacts change colors between clear and a deep, dark purple-brown. In bright, direct sunlight without sunglasses, the darkening effect is most pronounced. Most of the day, if you work in an office, you won't see much tint.
On my green-hazel colored eyes, these contacts turn a dark shade of purple-brown and entirely block out my iris's natural color. Like other soft contact lenses, these completely cover your pupil and iris, with a little overlap onto the rest of your eyeball. I have to admit, they give me a distinctly alien look that freaked out just about everyone I showed them to.
The Acuvue Transitions contacts might also benefit people who experience photophobia, which is brought on by a variety of conditions, including migraines and dry eye. For several days after I get a migraine, bright light is painful, focusing on a bright screen is hard and I'll get floaters in my vision. While these contact lenses cannot fix photophobia (which is a neurological issue), it can help make it easier to deal with the symptoms.
Even though Acuvue Oasys with Transitions lenses reach their darkest shade in sunny conditions, they are not a replacement for sunglasses. While the lenses do block UV radiation, sunglasses are important because they help protect your entire eye and the skin around it from UV damage that can cause cataracts, macular degeneration, corneal sunburn and skin cancer.
They also don't get as dark as sunglasses and don't offer polarization, which significantly reduces glare. If you already wear sunglasses regularly, these contacts will help you squint less if you step outside on a bright day without them. But you'll still want to use sunglasses to block additional light so it's easier to see. Plus, if your sunglasses block UV rays (which they should!) the contacts won't reach their full darkness, which minimizes the \"alien\" look.
Regardless if you wear sunglasses daily or not, you should know that, just like Transition lenses in eyeglasses, these contacts won't get darker when you're driving because car windshields block the UV rays from the sun that cause the lenses to react.
There are a few situations where I do feel like these contacts are a better alternative to sunglasses. First is the golden hour, just before the sun sets, when wearing sunglasses makes your vision too dark, but it's still too bright to not wear them at all. The same goes for overcast, foggy mornings, which are extremely common in San Francisco where I live, work and tested the lenses. With an overcast sky, the filtered sunlight is bright enough to bother my eyes, but if I put on sunglasses my vision seems too dark.
If you don't already wear contacts, your first step is to get an eye exam to get a contact lens prescription. If you already have a valid prescription, ask your doctor to get a trial pair of the Acuvue Oasys with Transitions, which should be free. You can also search on Acuvue's website to find doctors in your area that already have the Transitions lenses available to try.
For this story, I called my doctor's office (which also sells contacts and glasses onsite) and they ordered me a free trial pair. I picked them up and was told if I liked the lenses and wanted to switch to them, my doctor could write me a prescription for those specific lenses. Then I could buy full boxes, either there or anywhere else that sells contacts.
Not necessarily. Contacts vary wildly in price depending on the brand and where you buy them. Acuvue's rep told me that each doctor, optical retailer or online vision stores sets prices for the contacts they sell, so there's no one set price.
I currently wear Acuvue Oasys with Hydraclear Plus lenses, which are currently only sold in a 12 or 24 pack. Twelve-pack boxes online are priced around $35 to $70, depending on the retailer. All of these prices are out-of-pocket, without insurance.
If you're really keen to wear Acuvue Oasys with Transitions, crunch the numbers and see how their cost compares to what you currently wear. Since I can get a 12-pack of my current contacts for $34 ($2.83 per lens), I would save a lot by not making the switch.
Like my other Acuvue lenses, these Oasys with Transitions are meant to be worn daily for two weeks before you toss them for another pair. During the two weeks I tested these lenses, I felt conflicted.
I was blown away by how well they worked -- my light-sensitive eyes felt less strained and I wasn't as bothered by bright light. But, I was also discouraged by my friends' and colleagues' reaction to how the full darkened lenses looked in my eyes (when I purposely wore them outside without sunglasses). I can only be called a creepy alien so many times before the comment starts to sting.
I popped in a fresh pair of my usual contacts and headed out the door. As I walked towards my bus stop, I quickly realized how much the Transition lenses helped my eyes adjust to sunlight, especially on a foggy morning. And when I got to my office -- in sunny downtown SF -- the sunlight bouncing off the buildings and through the massive window next to my desk was more blinding and less tolerable than it had been with the Transitions lenses. Even staring at a computer screen, which is tough on my eyes and gives me occasional bouts of blurry vision, was a bit better with the Transitions contacts.
As I write this, it's been one week since I ditched the Transitions and I already miss them. So much so that once I make it through my current stash of \"regular\" lenses, I plan to make the switch back.
Update on September 4, 2019: After using my original contact lenses for a few weeks, I ponied up the money for a year supply of the Transitions contacts. I went from being super skeptical and kind of weirded out by how they made me eyes look, to a convert who cashed out some of her FSA to get them.
Vivi has 3 parts: a electronic circuit, which help image and light; a central portion, which is polarizing filters for viewing three-dimensional imagery; and an outer filter surrounding the central portion to make up the composite body of the contact lens.

Polarized, or anti-glare, sunglass lenses reduce light glare and eyestrain. Because of this, they improve vision and safety in the sun. When working or playing outdoors, you can become frustrated and even temporarily blinded by reflected light and glare. This is a potentially dangerous situation that polarization can prevent.
On polarized sunglasses, the filter creates vertical openings for light. Only light rays that approach your eyes vertically can fit through those openings. The lenses block all the horizontal light waves bouncing off a smooth pond or a shiny car hood, for instance.
People who use polarized sunglasses often say they are less tired than usual after hours of battling sun glare. Polarized sunglasses can be a good choice for most everyday situations. These are some specific situations when polarized sunglasses may be especially helpful:
The contact lenses are similar to \"transition\" glasses that get darker in strong sunlight but fade back to clear when inside. Those type of glasses, which rely on photochromic technology, have been around since the 1990s.
The approval was based in part on a clinical trial of 24 people, which showed that the contacts didn't interfere with driving either at night or during the day. \"The results of the study demonstrated there was no evidence of concerns with either driving performance or vision while wearing the lenses,\" according to the FDA. 781b155fdc
