I have worn glasses nearly all of my life. If I remove my glasses everything shrinks in size (a lot) and things get a little blurry. I have bad eyesight.
Years ago my first experience with scopes was interesting and annoying. I tried setting the scope up for use without glasses as recommended by a friend. That did not work for me, especially since I would be hunting, not sitting at a bench.
I found that with my eyeglass prescription there was a sweet spot just up and to the left of the focal point of my right lens. It to me some time to get the scope where I needed it by trying different mounts, but I did get it to where I could clearly see the scope and fire accurately from different positions.
Then a year went by, I got new glasses because my eyes change, therefore the prescription changed a little. I got new glasses.
These glasses didn’t have that “sweet spot” where the others did. My rifle didn’t hit exactly where it was aimed after using the new glasses. There wasn’t a huge difference in impact points but there was a difference and I had to adjust the scope to meet the new prescription.
I am not telling you this to dissuade you from wearing your glasses. I am telling you this to be aware that your prescription will change over time. Be sure and verify your scope alignment after getting different glasses. This holds true even if your prescription does not change. Labs making glasses may not make lenses exactly the same each time.
An example of that would be i once had a pair of regular glasses made and a pair of sunglasses made at the same time. With iron fights my rifles were all just fine when wearing the sun glasses. They hit true to aim. With my regular glasses they all shot 2-3 inches left at 100 yards. There was a change in my perception due to the contours of the different lenses. With my scoped rifles the difference wasn’t as dramatic, maybe 1” off but there was a difference.
I recommend that if you will wear the glasses all of the time then sight your guns with them on. When you change glasses OR prescriptions I would verify sight zero.
If they are solely for reading or driving and you wouldn’t be wearing them hunting then I would sight your guns without them.
One more piece of advice. Tell your optometrist that you are a shooter. If he or she is a good optometrist and has a good relationship with the lab making your glasses they can request the lab pay particular attention to making your lenses properly and consistently.
If your optometrist balks, displays resistance, makes excuses, acts funny upon the mention of guns, does not respond positively or anything other than saying “We can do that” then get up and leave and find an optometrist that will work with you. Been there done that. I don’t care if they have been your family eye doctor for years. Go elsewhere.
I know these things from experience. Learn from my experience, please and good luck. It is not the end of the world.
There are benefits to wearing glasses.
When a cold breeze is slapping you in the face they help protect your eyes and you can see when others can’t.
You can get them tinted to suit your needs.
They do offer some eye protection in heavy brush and in general.
If you have really bad vision and your lenses magnify you can start campfires when the sun is out. Haha
