Understanding the Cornea: A Marvel of the Human Eye

Today, I want to share something fascinating about one of my favorite parts of the eye. The cornea is the transparent, dome-shaped surface that covers the front of the eye, and it's the very first place where light enters our eye, allowing us to see clearly. But beyond its role in vision, the cornea is an extraordinary part of our anatomy for a few other reasons.

The Cornea's Unique Sensitivity

The cornea is the most highly innervated tissue in the entire human body. Meaning it has more nerve endings than any other part of us. It's an incredible generator of pain, something we’re acutely aware of whenever we get anything in our eyes.

To give you a sense of just how sensitive it is, the cornea's nerve endings are 40 times more dense th...

#1) The Best Sunglasses for Dry Eye Sufferers

When you have dry eyes, everything seems to make them worse. Your eyes are already irritated, anything like wind, dirt, dust, and even pollen makes your eyes feel more irritated.  How do you continue to look cool and keep your eyes feeling good all summer long?  

When you are outdoors, it is important to protect your eyes not only from the elements blowing into your eyes but also from UV light.  Let's discuss your sunglasses.  There are 3 things you want to look for in a pair of good sunglasses: protection, tint, and style. Check out the f...

If you have been hanging around with me for a while now, then you know that I preach the same rules over and over and over again.  In the past couple of weeks, I've been in the car a lot. So, I've had some thinking time. I started to re-evaluate my hard and fast rules.

I went to a funeral and a wedding in the same 10 day time span. To say the least, there was a bit of crying going on. And, it provided an opportunity for me to reevaluate some of the rules that I preach.

I would like to review these 4 dry eye rules.  Normally I'm quite the rule follower, but I had some reassessment time. And, it turns out that there are times when it's okay to break the rules.  Let me tell you when you can break three of them.  Then, I'll explain why you can never, ever, ever, ever, ever break one of them....

Happy New Year!

I like to take the time at the beginning of the year to think about where I am going on purpose.   A lot of times, we feel that life is just happening to us, but that is not the case.  We are all living the life that we ourselves have created. 

Take a minute to look back over 2021 and be thankful for all that you were able to create in your own life.  There is one accomplishment in 2021 that I am most proud of (see #3 below).  But, there were tons of accomplishments along the way as well.  Celebrating your wins is part of living a full life.  You put in the work to accomplish them, so don't hold back on giving yourself the credit you deserve. Here are 3 of my wins from this year:

1. 2021 marked my 20th year since graduation from Optometry School.  It's hard to believe I h

This week is Thanksgiving!  It is one of my favorite holidays.  I love to take the time to think back and remember all the things I can be grateful for in my life.  In this blog, I'll reveal the three things that I am thankful for in the dry eye world that are new this year in 2021.

#1) Innovation in Eye Care

There have been several new drugs that have gained FDA approval in the past couple of years to treat Dry Eye Disease.  The newest drug to receive approval is Tyrvaya.  It was just FDA approved in October.  It is a nasal spray for the treatment of dry eye disease.

A nasal spray!?!?!? Wow.  You won't need to be putting more drops in eyes that sting and burn.  Yay.  It's something completely different.  This nasal spray that stimulates your body to make its own real natural tears.  ...
