The following assessments can be combined with Snellen acuity test to help you understand where your patients are, and where they’d like to be with their near and distance vision.
- Near smart phone assessment: Smart phones have become the universal functional vision assessment. If a patient can see what’s on their phone, it’s likely they can see 95% of what they need to throughout the day.
- Distance office assessment: Have your patient take a walk around your practice after your initial examination. If they have taken a lap and are happy with what they are seeing distance-wise, you’ve reached your goal.
- Binocular Over-Refraction Test: In an open space with a binocular, have your patient look at the 20/25 distance chart and:
- Put the +1.00 trial lens in front of their left eye
- Using ± flippers over the right eye, have your patient star out with +0.25 lens to see if it makes their vision better or worse
- Then, have them try the +0.50 lens to see if that makes their vision better or worse
- If neither the +0.25 or +0.50 improves their vision, then you can consider using the -0.25. Just be careful not to introduce too much minus
- Next, switch eyes and with the +1.00 lens over the right eye, repeat the same process
Reversed Lens Check: Sometimes, patients’ vision problems are the result of a reversed lens. Using the inversion indicator, take a quick peek to make sure the lens is in proper orientation before doing any problem solving.
