How to increase reading speed?

I do not refer to speed reading.

Recent research in optics and neuroscience reveals that most people can at least double and perhaps even triple their reading speed if (a) they appreciate the fact that eyes are muscles and (b) eyes can be strengthened with practice exercises.

Most people are trained to read phonetically.

The speed of sound is 243 metres per second.

The speed of light is 299,792,458 metres per second.

Over time, it really is possible to strengthen your eyes with repetition of a few simple exercises.

For example, on average, I can now read and highlight a 300-page business book in about 45 minutes and retain most of what I have read.

If there is sufficient interest in this subject, I will be glad to share what I have learned.
