The Measuring Tape
Once you have a bit of practice, taking a centimeter measurement only takes a few seconds. You will use this for several purposes:
- Get a baseline reading before you begin your improvement journey.
- Measure for variance – How much your eyesight changes throughout a regular day.
- Measure for strain – How much your eyesight is affected by long hours in front of a computer.
- Measure for prescription – How strong your glasses should be.
That is a lot of information to get out of a single measurement!
