Nearsightedness; a Global Epidemic

More than just a vision issue, it’s a major health issue

Nearsightedness, clinically known as myopia, is a common vision disease that makes distant objects look blurry or out of focus – while objects up close will appear clear and in focus.

Nearsightedness is growing at epidemic rates worldwide – especially among children. Rates are climbing worldwide and are reaching epidemic proportions. Consider that nearsightedness has increased by 66% in the U.S. since 1971. Current projections estimate that by the year 2050 nearly 50% of the world’s population will be nearsighted.

Causes and Symptoms

Nearsightedness is caused by changes to the shape of the eye — specifically elongation or lengthening. This impairs the eye’s ability to properly focus light that is being projected on the back of the eye, called the retina.

Normal Eye Vs. Myopic Eye


Children whose parents are nearsighted or have a family history of myopia will have a higher risk of developing nearsightedness.


The second variable, and one that is thought by some researchers to play a tremendously powerful role, is lifestyle. The thought is that staring at any object, like cell phones, books, or tablets too long can cause the eye to lengthen, which can lead to nearsightedness. Common symptoms include:

  • Persistent squinting
  • Headaches due to eyestrain
  • The need to sit closer to the television, movie screen, or the front of the classroom
  • Holding books very close while reading
  • Not noticing distant objects
  • Blinking or rubbing eyes excessively


Paragon CRT® Contact Lenses

Freedom from Glasses and Daytime Contacts

Paragon CRT® Contact Lenses belong to a treatment option category called “Orthokeratology” (Ortho-K). CRT lenses are worn overnight and gently correct the curvature of the cornea while sleeping. In the morning, when the lenses are removed patients experience crisp, clear vision with freedom from daytime contacts or glasses.

Improve Your Child’s Quality of Life

Paragon CRT® can have a positive impact on quality of life, especially for children. Imagine your child being able to see with their natural eyesight during the day. Say goodbye to glasses, sports goggles, and daytime contacts! Lenses like Paragon CRT® have been clinically proven to improve a child’s:

  • Self-esteem
  • Performance in sports
  • Their willingness to try new things
  • Success in school
  • Social skills

More than an Inconvenience

For many patients, nearsightedness can become progressively worse over time. This is can be dangerous, especially when nearsightedness is diagnosed in childhood, as it can lead to potentially-blinding future vision complications later in life including:

  • Retinal Detachment
  • Myopic Macular Degeneration
  • Glaucoma
  • Premature Cataracts

In fact today, myopia is the leading cause of new cases of blindness in Tajimi, Japan and in Shanghai, China.

This is why it is so important to visit your eye doctor annually and to treat you or your child’s nearsightedness with the treatment option that works best for you and your family!

Are You or Your Child a Candidate?

There are no age restrictions for CRT. They can be worn by children and adults. Is CRT safe? Yes. In fact, Paragon CRT® contacts were the first FDA approved Ortho-K lenses for extended overnight wear.

When it comes to patient satisfaction, the results of a recent study show that 97% of Paragon CRT® wearers report that their experience either meets or exceeds expectations.

Ask your eyecare professional, if you’re interested in discovering if you or your child are a candidate for Paragon CRT®.

While there are other CRT-like lenses in the market, Paragon CRT® is the only brand trusted by patients in over 50 countries worldwide.7 Don’t settle for less. When meeting with your eye care professional, make sure you request Paragon CRT® by name.
