For you readers out there, here’s the answer in written form:

Today I’m going to teach you a little trick that most patients with astigmatism don’t know about their contact lenses!

First of all, if you wear contact lenses for astigmatism, you may have noticed that they are a little blurry for the first couple of minutes after you put them in.

Remember from episode 1 that people with astigmatism have a vertical prescription and a horizontal prescription. This means that your astigmatism contact lenses have two prescriptions built into them. If they rotate on your eye, it actually gives you the wrong prescription, since the axes of the two prescriptions aren’t lining up properly.

Fortunately, astigmatism contact lenses will auto-rotate to the correct position after 5-10 minutes. Some lenses adjust quickly, and others take longer. This depends on which brand you wear and how that brand fits your eye.

One thing you can do to speed up this adjustment period is to look at your contact lens markings before you put them on your eye. Didn’t know your astigmatism lenses have markings on them? Most people don’t.  That’s one of the reasons why your optometrist looks at your contact lenses with the microscope, to see if your lenses are rotating or not.

Try to find the marking yourself. If you can’t find it, do a google image search for your brand of contact lens and add “contact lens markings” so you can know where to find the marking. Some brands only have a single line, others have three. The longest line is supposed to down at the 6 o’clock position of your eye.

Once you’re able to find the marking and position it properly before putting it in, you will notice your vision adjusts more quickly.

If you are able to figure out the markings and how to rotate the lens before putting them on your eyes, congratulations! You’re now an expert astigmatism contact lens wearer.

If you are unable to find the markings (or don’t care to find them), no worries. Remember, they will auto-adjust after a couple of minutes, but at least you know why they are a little blurry for the first couple of minutes.

Hopefully, that makes more sense to you now. Now you know!
