Air Puff Test – What Is It For?

What is the purpose of that awful air puff? If you hate doing that test, you’re definitely not alone!

The air puff test is called non-contact tonometry (NCT) and it measures the pressure inside your eyes. The machine shoots a small puff of air into your eye, and it calculates the pressure inside your eye based on how the air bounces back.

If you can’t handle that test, there are alternatives such as Goldmann tonometry (the blue light test). This involves a yellow drop which glows under blue light. The doctor will view your eyes very closely with a prism, and then the pressure can be calculated based on how the light is bent.  This method is also painless, and even more accurate than the NCT.

Your eyes are filled with fluid, and if there is something causing a fluid buildup, the increased pressure can cause damage to the structures of your eye, resulting in vision loss. High pressures can be the first sign of glaucoma, or the result of other things such as injury, infection, or a tumour around the eye. There is usually no pain or symptoms with high eye pressure. It is like having high blood pressure – you won’t feel it unless it is at an unsafe level. That is why it’s important for an optometrist to do this test and measure your pressure every year. It’s a little uncomfortable but it’s over faster than a pressure cuff squeezing your arm! 🙂

Here‘s more Vision Therapy in the news!

1 in 4 students has a vision problem! 80% of what a child learns comes through vision, so a problem could prevent a child from earning the grades he/she should.

Here are some red flags:

  • headaches
  • complaints of not seeing the board
  • avoiding close work
  • child doesn’t like to read
  • doesn’t want to do homework
  • it takes hours to complete homework that should take 30 minutes

When Your Child Takes Hours To Finish Homework

Does your child take an unusually long time to finish homework? Do you have to get into a “homework war” every night to get things done? Your child is not being lazy. Homework might be very difficult and uncomfortable if he/she is suffering from a vision problem.

If you are baffled because your child is passing 20/20 vision tests, but still complains about reading the chalkboard or worksheets, has headaches or blurred vision, or is just plain struggling in school, it’s important to rule out any visual challenges. The first step is to book a Visual Skills Assessment.

When In Doubt, Take It Out!

Over the weekend, I encountered someone who was unwilling to stop wearing his contact lenses despite redness and irritation. This was at a social event, so I was unable to examine him properly, but I urged him to remove his lenses and visit his optometrist the next day. The rule of thumb is when in doubt, take it out! This is why it’s also important for contact lens wearers to have a good pair of glasses with a current prescription, in the event that you are unable to wear your contacts. He didn’t like wearing his glasses because the vision was not as good as with his contacts (perhaps an outdated prescription). For other people, it may be a vanity reason. In that case, it’s worth remembering that a big, red, drippy eye is not attractive either!

It is just not worth the risk. I was reminded of a recent news article where a student lost her eyesight as a result of over-wearing her contact lenses. She did not remove her limited-wear, disposable contact lenses for six months, and even wore them when swimming. Contact lenses decrease the amount of oxygen available to the cornea, especially when sleeping (even over one night!). This leaves them unhealthy and vulnerable to infection. Compounded with the bacteria from shower water and swimming pool water clinging onto the contacts, and you’ve got a recipe for an infection.

This girl was particularly unlucky, because Acanthamoeba infections are rare and extremely devastating for the cornea, but there are other bacteria in tap water and on the skin which are much more common and can also cause infections when the eyes are left vulnerable with contact lens over-wear. This case underscores the importance of using contact lenses as prescribed, taking them out every night, and disinfecting them with new solution every night. 

If your eyes look red, feel sore or painful, or have a gooey discharge, take your contacts out ASAP and go see your optometrist!
