They do it to overcome double vision, ghost images or cross-eye dominance - all of which can lead to serious accuracy problems.
Many shooters are affected by cross-eye dominance in which the dominant eye is opposite to the shooting hand, eg. strong shooting hand is right side, but dominant eye is left side. The purpose of the Magic Eye Dot, when applied to the lens of the shooting glasses over the non-shooting eye, is to subtly prevent the eye from focusing, while maintaining depth perception and peripheral vision.
Dot diameter: 20mm
In package: One sheet of 20 colored dots, 4 grey dots plus 2 grey rectangular strips - see product image.
Made in the USA!
Standing in front of a mirror, put your shooting glasses on and look straight ahead. Simply place a dot on your lens, to cover your iris and pupil area. If your right hand is your strong shooting hand, you will place the dot on your left lens, and vice versa. If you are cross-dominant, place the dot on the non-shooting eye. ie. right handed and left-eye dominant, place dot on left lens to force a switched focus to your right eye (shooting eye).
Several color dots are included, to get as close a match as possible to your lens color.
The dots are thin, sticky vinyl that can be lifted off the lens and moved or reused. If this is done multiple times, the edges of the sticker will start to crease. But it's definitely possible to move/re-use/re-position.
TIP: If you would rather have your dot on the inside of your lens, go through the steps above using a dot in a color you will not need. Once you have that dot in the correct position on the outside of the lens, remove the glasses, place the correct dot color at the same spot on the inside, and remove the outside dot. Test to fine-tune placement, to ensure your vision is slightly fuzzy in the non-shooting eye.
Which is your dominant eye? Here’s a simple test:
Extend your hands in front of your face. Place them together to form a small, triangular opening with your thumbs at the bottom. Using both eyes, look through the opening and focus on a distant object. Maintain your focus on that distant object. Now close one eye. If the object disappears from the opening, your closed eye is dominant. If it remains, your open eye is dominant.
Great product easily and cheaply results in immediate reversal of eye dominance to allow both eyes to remain open while shooting shotgun.
This product did not work for me but I'm sure it helps other shooters. Just thought I'd give it a try.
Color matches perfectly
I have Decot HY-WID prescription shooting glasses with 3 different colors of lenses. I was able to match each color perfectly. Have only used them once so far, but very satisfied with my purchase.
Best shotgun accessory ever
I have a strong cross dominance and tried the dots for the first time today. The results were amazing. Score greatly improved. I was going to give it a four due to cost but so far the improvement was worth it.
works for me
what I like if you are a little careful with your lens cleaning, the dot will stay in place. Just used mine first time in a hot, sweaty shoot. even though the glasses got sweaty, the dot stuck in place fine. Does seem to help with dominance issue. good product.
these dot's are fantastic , easy to use and no more ghosting of the barrel from my left eye
