Hello, thank you for always using Ondoku.
At times like these, there are many people who think, "I want to maintain my eye health."
However,
it is common to be unable to rest your eyes for reasons such as these.
For those who want to maintain eye health or find it difficult to read text due to eye strain, blurred vision, or presbyopia, I would like to suggest the solution of "using text-to-speech software."
Just having "someone read aloud for you" the small characters you encounter daily on computer screens, smartphones, newspapers, or documents can significantly reduce the burden on your eyes.
Even if you feel "guilty about troubling others...", it's okay!
By using text-to-speech software, you can have text read aloud without troubling anyone.
Text-to-speech software refers to software or services that convert characters, text, documents, etc., 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 enhancing your brain's comprehension.
When reading a text, following the text with your eyes while listening to the audio being read aloud allows you to understand the content more deeply than just performing silent reading with your eyes alone.
This is known as an effective study method, and it is said that using both eyes and ears improves comprehension and memory more than using only one or the other.
