Are these supposedly ';false advices'; regarding proper eye care really untrue? What do you think?

As I was reading Joyce M. Black’s Medical Surgical Nursing, 7th Edition, I read a boxed article which caught my attention. The article read as follows:





Common Misconception about vision and the Eyes





The following statements are often passed along as “advice.” All of the following are false:





1. Reading in the dark is harmful to the eyes


2. Children will outgrow crossed eyes.


3. A cataract is a film growing over the surface of the eye.


4. Cataracts must ripen before they are removed.


5. The surgeon takes out the eye to operate it.


6. A person with failing eyesight should avoid reading to save the eyes.


7. Children must be cautioned not to sit too close to the television.


8. Wearing someone else’s eyeglasses may damage your eyes.


9. Misuse of the eyes in childhood results in the need for eyeglasses later in life.


10. Cataracts can be removed by a laser.


11. Emotional stress increases intraocular pressure.





I know that some of the items presented are actually fallacious… but I’ve always though of items number 1, 7, 8 and 9 as facts. How come these items are actually false?





Please tell me what you think. As much as possible, please give scientific rationales.





Thank you and good day!Are these supposedly ';false advices'; regarding proper eye care really untrue? What do you think?
I think all of these being false would reflect the current establishment views on things. There is still some question about how myopia (near sightedness) develops. Some still believe there is an aspect of focusing up close that contributes to it. If that is the case than, 1 could be true of children and 9 may be true. Children don't sit close enough to the TV to have to focus very much. At one time there was fear about radiation from TVs damaging your eyes. Chances are right now you are sitting closer to a screen like what is used in TVs than you ever tried to as a child. Wearing other peoples glasses tends to get them out of adjustment.Are these supposedly ';false advices'; regarding proper eye care really untrue? What do you think?
I absolutely agree with all statements except for number 5, the eye is often sort of lifted from it's socket during some eye surgeries, not taken out but sort of lifted up.
