Why do humans have vision problems?

Hello Friends,

I know not EVERY human has a vision problem, and alot have perfect 20/20 eyesight their whole life, but why is my vision, for example, so bad? My contacts are numbered -6.50 (left) -6.00 (right). Neither my mom or dad have vision problems and neither did their parents. So why are my eyes bad? And their not just a little bad like my vision sucks! My eye doctor told me that my vision is worse than some adults!! Plus, I'm worried, Because my prescription is changing A LOT. So basically it would help me a lot of you could answer these three questions:
1. Why do humans have bad vision?
2. Why do I have such bad vision even though none of my family does?
3. Is it normal/bad/weird that my vision is changing so much? And what can I do to slow down the eye changing?

Thanks In Advance.
Simon Joseph

Re: Why do humans have vision problems?

i am no expert, but did u rub your eye often? squint to see things that is unclear to u / reading in a dark room / continuosly strained your eye like sitting on a computer 8 hrs straight...also if u have night vision problem like starburst / glare / halo, then u might have large pupils..i think those are contributing factors...

Re: Why do humans have vision problems?

Hi there! I don't think you have such a bad vision if all you have is -6.50 and -6.00 myopia!!! Most people with *serious* vision issues have really high myopia (> -9.00). So I'm not sure if myopia is your only problem.
As for genetics, maybe your parents' eyes were fine but how about your grandparents'? Sometimes, genes skip a generation.
Above all, you can help your eye with good nutrition (omega3 helps a lot) and a healthy lifestyle. You must protect your eyes from the sun and visit your eye doctor for regular check-ups.
The most worrying thing IMO is your prescription changing a lot/fast. What is your age? If you're still a teenager, this may explain it.
At some point, myopia gets stabilized.
Always get fitted for the right glasses for your eyes, never use somebody else's glasses or contacts, always follow your prescription from a reputable ophthalmologist and optometrist.
