Technology is changing the world. It has transformed the way we do everything from making a meal to hailing a taxi. Isn’t it about time that technology transformed the way we see the world?

Paragon Vision Sciences teamed up with NASA to do exactly that. From 1993-1996, Paragon scientists partnered with NASA’s Langley Research Center to conduct several experiments onboard the Space Shuttle during three separate missions.1 They sought to study and improve the high-performance plastics used in contact lenses and hoped that the effects of microgravity could help them better understand the large molecules they are made of. They aimed to better understand the chemical composition of these molecules, and thereby engineer a better contact lens. Thankfully, Paragon’s venture with NASA was a smashing success that led to material advances and innovative new technology.

Treating Vision Through Innovation

Leveraging discoveries from their experiments in space, Paragon Vision Sciences developed Paragon CRT® Contact Lenses. These contacts offer a completely fresh approach to the treatment of nearsightedness. Nearsightedness causes distance vision to be blurry. Nearsightedness occurs if the eyeball is too long or the cornea (the clear front cover of the eye) is too curved.

Paragon CRT® Contact Lenses are worn only at night. These specialized lenses gently correct the shape of the cornea while the wearer sleeps. In the morning, the contact lenses are removed for clear sight throughout the day, without the need for any additional daytime vision correction like glasses or daytime contacts!

A Better Option for You and Your Family

Also known as myopia, nearsightedness can be diagnosed as early as six years old and is increasingly affecting more and more people around the globe.2 By 2020, it is estimated that almost one-third of the world’s population will be myopic!2 Chances are, you or someone you know will be affected.

But a diagnosis of myopia no longer needs to be a cause for frustration. Thankfully, Paragon CRT® Contact Lenses have made addressing the symptoms of this vision condition easier than ever. There are no age restrictions for prescribing Paragon CRT®, and families can expect less hassle and fuss with an overnight treatment plan.3 Kids and adults alike will be freed from the worries of getting dirt in daytime contacts, breaking glasses, or losing either at an inopportune time. Overnight contact lenses offer a simple treatment option for nearsightedness.

Are You a Good Candidate?

Ready to move on from daytime vision correction? Paragon CRT® might be the perfect fit for you if:

      -You are unable to wear contacts due to dry eyes or allergies.
      -You find daytime contacts irritating or uncomfortable.
  • -Your contacts or glasses get in the way of your lifestyle and activities, such as sports, exercise, or swimming.
  • -You work in an environment that is not well suited to wearing contacts or glasses, such as one that is dusty, wet, or windy.
  • -You are not a good candidate for or have a child too young for LASIK.
  • -Your child’s issues in school are attributable to a vision problem.
  • -Your child is inhibited from activities by glasses.
  • -An inability to see clearly affects you or a loved one’s confidence.
  • -You or your loved one experiences eye strain or headaches as a result of nearsightedness.

Why continue to rely on a 20th-century treatment when there are better options available? Paragon Vision Sciences’ work with NASA moved the dial forward for the industry as a whole and brought a new level of comfort, ease, and safety to contact lens wearers everywhere.
