【Presbyopia, eye strain, blurred vision, etc.】A new proposal for those who want to maintain eye health. Text-to-speech software

Hello, thank you for always using Ondoku.

  • As you get older, it has become harder to see nearby text due to presbyopia.
  • Worried about whether your eyesight will deteriorate from looking at PC or smartphone screens too much.
  • By the evening, your eyes are tired and blurry, making it painful to look at small text.

There are many people who think, "I want to maintain my eye health" in such situations.

However,

  • It is necessary to read a lot of text every day
  • It is necessary to use a PC for work

For reasons such as these, it is common to find it difficult to rest your eyes.

To those who want to maintain their eye health, or find it difficult to read text due to eyestrain, blurred vision, or presbyopia, the solution we would like to propose is "using text-to-speech software."

Text-to-speech software is recommended for maintaining eye health

Burden on eyes from PC

By simply having "someone else read aloud for you" the small text you encounter daily, such as PC text, smartphones, newspapers, and documents, you can significantly reduce the burden on your eyes.

Even if you feel, "I feel bad about bothering others...", it's okay!

By using text-to-speech software, you can have text read aloud to you without bothering anyone.

Text-to-speech software refers to software or services that convert characters, text, and documents into audio and read them aloud.

The function of reading text on your behalf is more convenient than you might think.

Not only does it rest your eyes, but it also has the effect of increasing the brain's comprehension.

Combining with silent reading is also recommended

When reading text, instead of just reading silently with your eyes, you can understand the content more deeply by following the text with your eyes while listening to the audio being read aloud.

This is known as an effective study method, and it is said that using both eyes and ears increases comprehension and memory compared to using only one.
