How do you live your life? Do you swim every day, hike on the weekends, or hunt down the most challenging boulder problems to conquer? Do you live life to the fullest? If you do, then you don’t accept limits. So why accept limits on your vision?

Meet Sierra Blair-Coyle, an Arizona local whose been competing professionally in rock climbing since the age of 14. Sierra has been a Paragon CRT® patient for 10 years and has enjoyed an active lifestyle without the limitations of glasses or daytime contacts.

“Paragon CRT® is so easy to use and gives me freedom to climb while not
having to worry about my glasses fogging up or getting chalk in my contact lens,”
– Sierra Blair Coyle

When worn overnight, Paragon CRT® Contact Lenses treat nearsightedness, also known as myopia. These lenses gently reshape the curvature of the cornea while you sleep. When you get up for that morning jog or sunrise bike ride you remove the lenses and see clearly all day without glasses or daytime contacts.

From the Bottom to the Top, See Clearly

Sierra’s family decided that Paragon CRT® was the right choice for her lifestyle when she was 9 years old. According to Lisa Coyle, Sierra’s mom, “Sierra’s vision problems were increasing at a rapid rate of three times per year. I am thankful Sierra’s eye doctor recommended Paragon CRT®. Not having to wear glasses or daytime contacts gave her more confidence during competition.”

Sierra got her start winning climbing competitions as a child, now she is a professional rock climber who competes in competitions all over the world and is on the USA Rock Climbing team. She doesn’t believe in limits and her life shows it!

  • World Cup Competitor from 2010-2018
  • Two-time National Champion as a junior competitor

When taking on a boulder problem or route Sierra does not have to worry about breaking her glasses because of a fall or having them slip down because of sweat. Sierra doesn’t have to stress about chalk getting uncomfortably stuck to her contact lenses. Sierra has freedom to see and experience her life to the fullest.

 What does ‘It’s Your Life… See it Without Limits’ mean to Sierra?
“Pushing yourself and doing whatever you want, and whatever you can and not let anything limit you.”
