In this step by step article about Corrective Glasses for Senior Shooters I am specifically referring to shooters who suffer from presbyopia or farsightedness. The methodology employed is to get the front sight as sharp as possible, whilst maintaining a good view of the actual target. This lens arrangement is not going to be suitable for daily use. This arrangement is specifically for shooting glasses,
Step 1. Measure the distance to your Front Sight
Some Optometrists may not be too delighted if you haul out your Glock in the consulting room so I suggest taking this measurement at home. Adopt your normal comfortable shooting stance. Aim at a point about chest height and get an assistant to take the measurement from your brow to the font sight. Then armed with this information – definitely no pun intended – make an appointment with your Optometrist.
Step 2. Minimum corrective script for your Dominant Eye
Explain to your optometrist that you are getting corrective lenses for your shooting activities. You may need to further explain the importance of being able to have a clear front sight to achieve accurate shooting and high scores. Give the optometrist the measurement that your front sight is from your brow, the Optom will then probably hold up a reading card at that distance and give you a selection of lenses. You will tell him which one makes the text look the sharpest. You should then ask the optometrist to give you advice on the minimum corrective script you should use for your dominant eye. What we refer to here is that it may not be necessary to use the lens that makes the text look the sharpest as that may make the target too blurry. So this is a compromise between “good enough” sharpness of the front sight and still maintaining a bit of distance vision.
Step 3. Test The non dominant eye for distance only
Ok now that the difficult part is out of the way ask the optometrist to check and if necessary give you a distance script for your non-dominant eye.
Step 4. Mail us the Script
Make sure the script has a PD or pupil distance on it and take a pic of it and mail it to us at info@theglockshop.co.za. Once we receive the script we send it off to our lab and it takes about 3 days to get the lenses. Your glasses are then packed and couriered to you.
