- Make sure the switch at the top of the device is turned ON! Talk to the patient to ensure that they are still seeing the red light clearly coming from the auto refractor. They should see the red light filling the center and ask them to look at the red light and then look PAST it. Then ask them to FOCUS ON THE TARGET with BOTH eyes.
Take a moment before tapping on the screen to capture the images.
Is the red grid centered?
Is the patient comfortable?
Do you need to adjust the stand?
Is their head parallel to the device?
Is the eyecup adjusted correctly as to prevent ambient lighting from entering the device?
2. Make sure they are seeing a good target!!
The best targets are mirrors! If you don't have a Smart Vision Labs focus target, please reach out to the team at email@example.com
Patients eyesight are not adjusting to a canvas or eye chart that may be too high or too low for their line of vision. We want them to look straight ahead from 10 feet!
Repeat for them to focus on their target about 10 x before tapping on the screen to ensure they are getting a good AR.
Some examples of a good target is a mirror or canvas picture.
Are they only able to see from 3 to 5 feet?
- Check their lensometer readings/contacts if they have really bad eyesight.
- Wave your hand as a target at 3 to 5 feet, if they can only see that far.
- Then accommodate for their target at that distance.
