Howdy all. Will a slight change in an eye prescription have an effect on parallax and ranging or am I nuts? ( rhetorical question, all airgunners are nuts on some level) Recently I went to the eye doctor and had an eye exam. It was a required visit to get contacts even though my prescription hasnt budged in years. To my surprise my shooting eye was weak by a quarter point. Not enough for me to notice it really, been just fine wearing contacts and using reading glasses. Doctor said my left eye was compensating for it. New multifocal contacts ( ditched the readers) and went a shooting. ( fwiw they are amazing, best vision ive ever had) BUT Apparently my parallax ranged and marked marked scopes need to be adjusted now. Reticle obviously needs to be focused again from the multifocal lenses and ditching the readers, but the quarter point prescription change seems to have also offset my distance markings as well, not much, maybe a couple of yards. Anyone else experienced this or similar?
The rifle still shoots the same too, no chrony drop, same ammo, same ballistics, basically the same weather too. I confirmed drop to 55 yds and nothing changed with the rifle. I can say there must have been eye strain i never noticed, its much easier to shoot long sessions now and practicing with open sights is much easier too. I can speculate to why only my shooting eye changed, maybe staring at an ATN scope screen for hours at night or just age, but thats not the point or the question here. Has anyone else noticed a parallax ranging shift or offset from a eye prescription change? Thanks in advance and thanks for reading.
