Easy Vision Log 1.13.2

The application offers a streamlined method for recording visual acuity assessments using a smartphone or tablet. Users can simply flick the screen to initiate the test, with adjustable distance settings to modify the size of the optotype (such as Landolt rings or E charts) based on the user's proximity. This feature allows for consistent testing conditions tailored to individual setups.

Measurement data can be saved after each session, enabling users to monitor their visual acuity over time and compare results between their left and right eyes on a monthly basis. However, due to inherent physical constraints of mobile devices, the results should be regarded as approximate guidelines rather than precise diagnostics.

Designed for ease of use, the app employs a flick input method instead of traditional buttons, facilitating a natural posture during testing, which is especially beneficial when testing with smartphones. Response controls are strategically placed on either side of the screen to accommodate right- or left-handed operation, particularly when using tablets held with both hands.

Display accuracy is maintained by adjusting the size of optotypes according to the set distance, with device-specific calibration ensuring consistency across different screen resolutions and dpi settings. Users can also manually fine-tune these parameters if desired, using common measurement tools such as rulers or quarter rulers.

The app provides comprehensive tracking features. Results include details like measurement date, eye tested, whether the naked eye or corrective lenses were used, and additional conditions. The data can be sorted or filtered—for instance, by eye or date—allowing for detailed review and monitoring of visual changes over time.

In terms of optotype options, the app supports both the internationally recognized E chart and the Landolt ring, reflecting language-specific standards—English and Japanese respectively. Users may choose based on their familiarity or preference, noting that the measurement procedure remains consistent regardless of selection.

Additional customization options are available within settings. Users can personalize themes with four color choices and adjust various preferences, including sound effects for responses and initial difficulty levels. A hidden feature may also exist within the settings menu for exploration.

It must be emphasized that due to variations in display resolution and brightness among devices, results should be viewed as general guidelines rather than definitive assessments. For accurate diagnosis and measurement, professional evaluation at a specialized facility is recommended.
