Wearing glasses and using a rifle scope

 Wearing Glasses and Using a Rifle Scope

BCT Quick Tips:

All sorts has been said about this over the internet.

Here are the starting facts:

Scope in Use is a Vortex Crossfire II 3-9X40,

So this means it has from X3- X9 magnification range and the front optic diameter is 40mm (not a 40mm focal length- just to be clear). 

Using it at over X4 when wearing glasses isn't recommend by me as any slight head movement (hence eye movement) you will not be able to see through the lens quickly as the magnification increases the field of view decreases and this means (in practical terms) the alignment of your eye must be exactly on optical axis. Now this latter aspect is really important if you wear glasses to read* and see stuff at close range.

* I'm only considering glasses for reading here, not for any other kind of optical astigmatism corrections etc.

I got this scope because it isn't too bad in low light so anything like this will help if one wears glasses for reading and or their vision becomes worse in low light cf with strong bright daylight when your iris is stopping down which helps to correct for poor vision due to the age of your eyes but in low light without glasses this can be a problem when the Iris opens up to let more light in.

The importance of a good and repeatable cheek weld is paramount but before this the wearer of glasses can not be as sloppy as someone who doesn't wear glasses when setting up the correct eye relief. 

The reason why this is important is because you want to be able maximise whatever eye relief your scope has for proper vision and of course is all part of shooting skills.

Be sure to correctly focus the reticle and once focused do not change this to see what you are aiming at. Make sure your frames keep your glasses close to your face and are not slopping around because you will be turning your head in a position which is not normal when reading and if your lenses slip.

Depending upon the glasses (eg reading glasses), wearing them will/could give you a slight magnification increase to whatever the scope is set to.
