How to confirm Myopia?

Myopia = Nearsightedness

This is when a person sees near objects clearly while distant objects appear blurred.

Nearsightedness can be corrected with eyeglasses or contact lenses that extend the point at which light rays focus. Another option for some nearsighted people is laser surgery.


I don't understand this measure, can you explain what these numbers represent?

I am nearsighted with -4 diopters, that keep changing between -4 to -5 diopters,and not stable during test.
-4 diopters (original from glass)


Do you have any suggestions on what is going on within eyes under this situations?
Thank you very much for any suggestions (^v^)

That is no cause for alarm, why is it a concern to you?

Does my eyesight get worse? what is going wrong within eye structures for blurred image ?
Do you have any suggestions?
Thank you very much for any suggestions (^v^)

If you test -4, then -5 a few weeks later, then take the average of the two. If you aren't noticing a change in your eyesight, you shouldn't jump to the conclusion that your eyesight is deteriorating. I'm betting that a third reading will be either -4 or -5.

I suspect that is a false nearsighted , and would like to know on what is the possible cause for this situation within eye's structure.

The cause is still unknown, though people with light-colored eyes or a family history of macular degeneration are more vulnerable. Through research on the mutated gene that causes Stargardt disease, scientists have discovered what they believe to be a genetic trigger for the disease. Researchers have found that 16 percent of macular degeneration patients have alterations in this same gene. Through this growing body of research, many scientists now consider heredity to be a significant risk factor in macular degeneration. Some evidence suggests that smokers - particularly women - and people who spend a great deal of time outdoors without eyewear that offers protection from the sun’s ultraviolet rays may have a higher rate of macular degeneration. Hypertension also appears to increase a person’s risk of developing macular degeneration.



Vision Loss Due to Macular Degeneration

I would like to know on whether there are more Macular Degeneration cases recently or not as comparing 30 years ago, since we spend more time in front of computer or mobile recently.

Is there any related articles about this issue?
Do you have any suggestions?
Thank you very much for any suggestions (^v^)

I can't find  study that suggests macular degeneration having risen over the century. Are you making a blind assumption or is your hypothesis backed by an idea that you heard or read?

There was not much people using computer and LED equipment before 1990 (30 years ago).
I suspect that blue light is the main source to damage retina, which relate to Macular Degeneration.

What do you think?
Thank you very much for any suggestions (^v^)

Hi oemBiology

According to this article, "blue light from electronic devices is not going to increase the risk of macular degeneration or harm any other part of the eye." If blue light is a concern, however, it can be blocked from your mobile devices and computer monitor.
