Easy Vision Log

Easily record your vision with your smartphone

+++ App description +++

An application that allows you to easily record your vision simply by flicking the screen on your smartphone. (Tablets are also supported).
Set the distance from your eyes to your smartphone to change the size of the optotype (Landolt ring/E chart) displayed according to the set distance.

Measurement results can be recorded each time, allowing you to easily track your eyesight and differences between your left and right eyes on a monthly basis.

Due to physical device restrictions, it is difficult to ensure a completely accurate vision measurement, so please only use the results as a guideline.

For example, you can use the app when renewing your driver's license or as practice/mental preparation before a vision measurement at your health checkup!

+++ A simple interface +++

Unlike vision measurement apps where you input your response by tapping a button, this app uses flick input, allowing you to maintain a natural posture throughout the test even when measuring with a smartphone.

Response buttons are positioned on both sides of the screen in consideration of the fact that tablets are held with both hands, so you can input responses with your dominant hand.

+++ E-chart and Landolt ring sizes displayed with accuracy

Set the distance between your smartphone and your eyes to display E charts or Landolt rings on your screen in a size according to the distance set.

The same optotype size will be shown on displays with different specifications since dpi and resolution are acquired for each device.

In general, there are no problems with the default settings, but you can also manually adjust the settings using a quarter or ruler.

+++ Keep a record of your vision +++

You can record and track your vision measurement results.
In addition to the date and vision result, other measurement conditions include the eye(s) measured, whether the measurement was taken of your naked eye, and whether or not you were wearing glasses or contacts, allowing for easy review of detailed measurements.

Results can also be reordered and narrowed down to display items such as only the measurement results of the right eye or of the naked eye, or the oldest measurements first.

+++ Choose from E chart/Landolt rings measurement marks +++
