These Transitions contact lenses get dark in the sun

I step outside of my office on a sunny morning and the intense bright light makes me squint. Instead of reaching for my sunglasses like I always do, I wait a few seconds for my new contact lenses to adjust to the light. Within 30 seconds, the sunlight is less intense -- almost like I am wearing sunglasses, but not quite.To get more news about colored contacts cheap, you can visit beauon.com official website.

I've worn Acuvue Oasys contacts for 12 years, but for the past two weeks I swapped out my usual lenses for Acuvue's new Oasys with Transitions Light Intelligent Technology soft contact lenses, which adapt to different lighting conditions automatically. I'll bet you already know what Transition lenses are -- those glasses that turn dark in the sun and go back to clear when you step indoors.

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.To get more news about Blue Contacts, you can visit beauon.com official website.

I should note that Acuvue's other contacts, and contact lenses from other brands -- such as Biotrue and Clariti -- also block UV radiation, but stay clear in all light.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.With filtered sunlight on a cloudy day, they will still adjust, just to a lighter shade of purplish brown. Even when I take them out at night, after the sun's gone down and I've been watching TV or fussing with my phone, they have a faint purple/brown tint as I put them in a case. By morning, they are nearly clear.

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.
