Archery, Aiming and Glasses Vs Contacts

Today one of my archery students was having a problem with the contact in the eye that he aims with. He used to wear glasses, but has made the switch to contacts. His contact was making his eye itchy and dry, and this was interfering with his ability to aim.

The quality of his aim today was thus suffering.

Logically, today would have been a good day for him to switch back to his glasses.

So does that make glasses better than contacts when it comes to aiming?

Not necessarily. The problem with glasses is that they will sometimes shift on your nose, thus shifting the magnification you are using to aim. Ideally, if the glasses were always perched on the same part of your nose then it would be okay, so the trick then is for glasses-wearers to adjust their glasses before a shot, and make a habit of doing it before shots.

Contacts, assuming that the user's eyes are not dry / irritated, thus would normally be superior. There are certainly pros and cons to both.

GADGET NOTE

There are also "Archery Sport Glasses", which are designed to give the user a greater focus / magnification so they can more clearly see where they are aiming, without squinting or straining their eyes. The lenses can also be adjusted to full sun or low light conditions. Some people consider "Archery Sport Glasses" to be cheating, akin to using other kinds of archery gadgets, and thus they might not be allowed at some kinds of archery competitions. It is more common to see them at compound archery competitions, which are very "pro gadgets" in the first place.
