Eye Ruler helps you track your myopia over time by recording how far you can see clearly without glasses or contact lenses. By measuring regularly and logging your results, you can observe trends and see whether your eyesight is improving, stable, or getting worse.
What do I need to measure my eyes?
Very little — a tape measure is the only thing you truly need, and text you already own works fine as the target.
- A retractable fabric tape measure — the essential tool. A soft, retractable one is easier to hold at eye level than a rigid builder's tape, and centimeters are the unit Eye Ruler records.
- A Snellen eye chart — optional. Useful for checking distance visual acuity alongside your blur distance, but not required to start.
What matters far more than the gear is using the same text, lighting, and time of day every session, so your measurements are comparable to each other.
Find a book, magazine, or website that you can consistely use. Hold a tape measure at eye level and find the furthest point at which small text stays clear or starts to become SLIGHTLY blurry. Record that distance in centimeters. For "both eyes," keep both eyes open. For individual measurements, cover one eye at a time.
How often should I measure?
Daily measurements give the most useful data. Try to measure at the same time of day and under the same conditions (e.g., same lighting, same text size) so results are comparable. You can also measure more regularly, for example: once in the morning when you take up, once during day after lunch, and once in the evening before going to sleep
What affects my measurements?
Sleep, stress, eye strain, screen time, and diet can all affect your blur distance on a given day. Use the Notes field when recording a measurement to track these factors over time.
How can I improve my eyesight?
The first step is to measure! Then try to find what affects those measurements both in a positive way and a negative way. Some important things are to avoid screen time as much as possible and maximize time outside looking into the distance.
What are common mistakes?
Rushing the process, not logging consistently, and ignoring lifestyle factors are the most common pitfalls. For a breakdown, see
