What symptoms differentiate degenerative myopia from normal childhood myopia?

Degenerative myopia is a severe form of nearsightedness that damages the retina. The retina is what lets you ‘capture’ images in order to send them to your brain. This is important as an eye doctor can check for retinal damage during an eye exam. Your doctor will widen (dilate) your eyes in order to see your retinas. Both types of myopia result in your eyeball being stretched, but degenerative myopia means there is damage to the tissues in the eye. Tissue damage does increase the possibility of sight loss. Degenerative myopia can lead to macula issues.

Will reading while lying down worsen myopia?

Actually, reading while lying down by itself has no effect on eyesight. This is provided that you do keep a good reading distance and have adequate light. A good reading distance is about 20 to 30cm. Any form of close reading in any type of position can be considered near-work, which should be avoided. However, reading while lying down is discouraged because gravity pulls your book towards you. That said, it is more likely you will not keep a good reading distance.
