Reading Check — I See You All

Before we start

This is a comfort check, not a medical exam. It suggests a starting range of reading strength that may work for comfortable reading — it cannot measure eye health, and it is not a prescription.
For adults, and for children only with a parent or guardian alongside.
Not for driving. This checks near (reading) vision only — how you see at distance, including for driving, needs a full eye exam.
Have a bank or credit card ready. Every card is the same size, and matching one to the screen sets the scale for the reading lines.

Safety check — mark anything that's true right now or was very recent

Sudden vision loss, or a sudden big change in how clearly you see New flashes of light, or a sudden shower of new floaters A dark curtain or shadow moving across your vision Significant eye pain, or an injury to the eye New double vision

Please don't use this check — seek care promptly. Any of these can be a sign of something that needs attention the same day. Contact an eye doctor, an urgent care clinic, or an emergency department today. I See You All can still help you get somewhere to be seen — request help and Marie will follow up — but the comfort check itself will not run.

Nothing is stored until you finish the check.

Step 1 · Calibrate the screen with a bank card

Hold any bank or credit card flat against the screen, over the rectangle below, and drag the slider until the rectangle's edges sit exactly under the card's edges. Every card is the same size — 85.60 × 53.98 mm — so matching one sets the scale everything else is measured at.

Step 2 · The reading check

Hold the page about 40 cm from your eyes — one forearm, elbow to fingertips. Read down the lines and tick every one you can read comfortably, all the way across, without straining. The lines get smaller; we use the smallest one you tick.
