Vision – Glasses, Contacts and Archery

Being an archer, competitive or recreational, does not require perfect 20/20 vision. E Perez asked…

I’m not sure if you’ve worn glasses before but if so, do you have any suggestions on archers who used glasses and are now switching to contacts? I’ve recently switched from glasses to contacts and my aiming is way off!

I can relate to this question, when I started shooting I had 20/20 vision, and around high school I needed glasses. I have not tried contacts yet, however it was an adjustment. Remember, the purpose of a corrective lens helps refract the light or images into in focus so you can see. Check out this website that explains how your vision works and how corrective lenses affect vision.

Wearing glasses or contacts can sometimes be a challenge for archers, since we actually stand to the side of the bow, not directly behind it. Therefore we are always viewing things on an angle, add the complexity of a corrective lens and it may be difficult to clearly focus on the target. It depends on the strength and thickness of the corrective lenses. I have a friend who can not shoot with her contacts on. The angle of the bow, combined with the angle of her contacts and she can not see her string alignment at all, which can affect your group.

Picking glasses out also presents a challenge because of the angle of the lenses and the thickness of the frames. My sister can not shoot with her prescription glasses because the frames are too large for the angle of the bow and she can not see her string alignment. If you need corrective lenses, it may take some trial and error experimenting to find out what works best for you.

I’ve recently switched from glasses to contacts and my aiming is way off!

If you are able to see the target and string alignment in focus, consider your arrow groupings.

Groups open up: Your brain could be simply catching up with your new perception, give it some time and practice. If the groups do not get better, then try shooting with your glasses on again and comparing the results.

Groups still tight; just off center: Move the sight. Even the smallest change can affect everything else, your vision is a large change.

Moved your sight; no change: Check your form, since many things can affect your your arrows including plucking the string.

Vision is important however not as important as good form. In fact, you may have read my earlier blog about legally blind South Korean archer, Im Dong-hyun, who broke the world record at the London 2012 Olympic Games. Im Dong-hyun has only about 20% vision in his right eye and only 10% in his left eye.

Your vision is important, however you may want to focus on making sure the shot “feels” the same every time, this is the key to success. For me, my coach still insists everyone warm-up with the following exercise to help us focus on feel not vision.

Close-Open-Close Warm-up 

1. Close your eyes and draw your bow to full draw; focusing on your form. Try to make sure all your muscles and bones are in the same position with the same amount of pressure
2. Quickly open your eyes to move the sight to the target
3. Close your eyes and then shoot.

I hope I have provided some guidance and answered your question. If any other readers have experienced changes from moving to contacts from glasses, we would love to hear from you.

Adjusting your sights

As a recurve archer, your sight is a vital piece of your equipment. Recently, I had a request to do a blog about the anatomy of a sight and how to adjust it. Although every sight is different, they all have similar components. We will use the Cartel Mighty sight in this example.

A recurve sight is typically made of four components; the riser mount with knob, horizontal extension bar, vertical sight bar, and scope. The riser mount is used to attach the sight to the riser and the knob is used to hold one end of the horizontal extension bar. The vertical sight bar is mounted to the other end of horizontal extension bar with the scope attached to it.  The vertical sight bar and scope have thumb screws that are used to adjust and micro-adjust the scope in relationship to the target.

Most sights have three knobs, one to adjust the length of the horizontal extension bar, one to adjust the height of the scope and one to adjust the left/right location of scope. The latter two usually have both large and micro-adjustments available. When you are ready to start adjusting your sight, remember the simple rule, “Follow the arrow”. Check out my earlier blog called Follow the Arrow: Adjust your sights.

To adjust the length of the horizontal extension bar simply loosen the knob and extend it to the desired length and tighten the knob to secure it. The marks on the bar to help you remember the length so you can set it up again.

To make an adjustment of the vertical location of the scope, loosen the thumb screw fastener and either depress the thumb lever for a large move or turn the micro-knob for small adjustment. Once complete then tighten the thumb screw fastener to secure it.

To make a left or right adjustment of the scope, loosen the thumb screw fastener and either twist the scope in or out for a large change, or twist the tension knob for micro-adjustments and then tighten the thumb screw fastener to secure it.

Once you have adjusted your sight make sure to shoot several arrows to confirm your adjustments. Once you are satisfied with the results, record the location of the sight marks on the vertical sight bar. Remember as you grow, develop muscle and change equipment your sight marks will move. One trick is to add a thin piece of white tape over the sight marks. This allows you to adjust the markings without permanently damaging the sight itself.
