The lens hardens as you get older, thus it cannot change focus so easily, you can keep it exersised by regularly focussing on different distances.
Unfortunately as soon as you get glasses, that makes the situation worse as the eye gets even lazier.
However, when you reach your fifties, your eyesight can can actually improve slightly.
I don't think there is much you can do to prevent it |

Two of the most common reasons why the eyes deteriate are :
Liftin heavy objects : (Pressure).
This puts pressure on the eyes as well as the heart. You have to remember to breath deeply while lifting .... don't stop breathing.
Diabeties : .... (I've been one for 35 years).
Which causes haemorraging in the eyes (I have laser treatment for that), glaucoma (just had tubes inserted in my left eye which reduces the pressure in the eye), lens replacement (had one of those as well).
You can't really do much to prevent deteriation, just look after them, and go them them checked once a year.
Good luck (again). |

Lots of things things, You would have to get a Consultant Ophthalmologist to diagnosed you Properly as your GP could not do it. I have had lots of eye operations and if you are worried the sooner you get them seen to the better.Good Luck. |

Excessive stress to your eyes is the most common cause of deterioration in vision.
In this era of Computers and Cable TV, try to give a rest of five minutes to your eyes after each half an hour or forty five minutes on computers or while watching TV. |

High blood pressure is one of the main causes of eye degeneration (macular) and it is important to aim for a normal blood pressure. Luten supplements provide the right nutrients for the eye. However, most eyes deteriorate through age with short/long sight being the main problem.
It is important to have your eyes tested regularly especially if you notice any changes in your vision.
Contrary to belief eye execrcises do not prevent eye deteriation but help to stop eye strain.
It is also important to wear UV sun glasses when out in the sun as UV rays are very harmful to the eyes. The lens of your sun glasses should preferably come round the side of your eyes as well.
There are lots of well designed sun glasses around to choose from but do not be tempted by the asthetics alone you need good quality lenses.
Blueberrys are also good for the eyes. |

Unfortunately there is nothing that can be done about anyones eye sight as they grow older.
In age your eyes become lazy and we dont use them to there full potential therefore the muscles harden, this causes a deteriation in the eye hence generally from around 50 onwards you will require reading glasses. There is nothing other than surgery that can be done.
As in surgery what i mean is there is a procedure called Restor lens which are inserted into the eye, They are basically a contact lens which is inserted through a small flap in the cornea. IT is a relatively easy procedure but very costly

I hope this information helps, oh the joys of getting older!!!

Mainly age. The muscles of the eyes weaken the same as the other muscles of your body as you get older.There is not much you can do about it.Have your eyes tested at least every two years,and wear glasses or contact lenses to correct any sight deficiencies.This will probably be an ongoing thing from middle to old age.There are some illnesses that can cause eye problems.Diabetes for example,but again regular testing will enable most problems to be overcome.Apart from the quality of your vision, testing will also highlight the incidence of cataracts or glaucoma,.both of which can be treated to avoid serious sight loss. |

your eyes can get weaker over your lifetime, if your close up vision is getting blurred all of a sudden, get yourself checked as it may be diabetes.... check with optician/doctor |

In addition to the other answers, despite what we have been led to believe, tanning [natural or artificial] is dangerous to the skin and the eyes in different ways.
It is important to have proper sun-glasses and/or a wide-brimmed hat, when out on a sunny day. Reflected light also poses a danger. |

Diet. Eat plenty of fresh fruits and green vegetables. Also drink at least a glass of milk (unboiled/unheated) a day without any additives like sugar or ovaltine.
Finally, avoid smokey areas such as pubs or other similar public places where smoking is rampant!
Also, I would butter my toast despite what some say it is bad for heart. Butter contains vitamins A, D, and E naturally.
Hope this helps. |

Poor diet in particular lack of vitamin a. Age can have an effect.
When i was young i was always told not to read in the dark or sit too close to the television but the optician told me that in teenage years as your body changes the shape of your eye ball can change causing problems with sight. I became short sighted. As i am growing older my eyesight appears to be getting better but i am told by the optician i am actually becoming more long sighted and eventually it will go the other way this happens with age apparently.
I think some of it may also be to do with genetics as i am always asked about family history too.
Eye strain could also be a factor. Using the computer or doing a lot of reading could put more strain on the eyes. Whe i was working i was told to take a short break from the computer every hour partly to rest my back but also perhaps to rest my eyes. |

The most important thing of all is to not take your eyes for granted. Even if you do not wear glasses and your vision is excellent you need to get them checked regularly. Eye disease can creep up on you and by the time you actually get symptoms it can be too late. Believe me, I went from 20/20 vision to blind in one eye in just 6 months, despite constant treatment and a brilliant eye specialist. |

There are various causes for example cataracts or glaucoma, both can be medically treated. Age degeneration, your genetics, diabetes or trauma are other causes of deterioration.
Regular eye tests will help prevent deterioration, protecting your eyes from the suns rays (with proper sunglasses with a high UV protection) will also help. Vitamin A is also essential for healthy eyes. |

There are a myriad reasons for the deterioration of vision. However, everyone one of us, if we lived long enough would go blind.
The aging body is beset with problems - it has lived through what animals would deem its useful period, i.e. to reproduce and protect its young and doesn't seem to give a gnat's chuff about sensory perceptions.
A major problem is cataracts - hihg exposure to UV will heighten this but as you get older the tightly packed and well arranged structures start to lose this, and lose their transparency. THere are various types of cataract but senile onset is inevitable, although you can be born with it or suffer it through trauma. No real way to prevent it but you can treat it by removing cataract and replacing with a plastic lens.
Diabetic retinopathy is a major source of vision loss; this is where those suffering from diabetes eventually start to have areas where a build up of waste products and paucity of oxygen cause the body to build new vessels over the retina (nerve and light receptor filled part of the eye) and thus cause blindness.
Want to prevent it? Keep a healthy diet and keep getting regular check ups with your doctor and optometrist.
Contact lenses can cause blindness in anumber of ways. If you get them dirty, or have something stuck underneath your contact then this can cause corneal (transparent window at front of eye) scarring. Transplants are available but you're left scarred forever.
Also, when wearing contact lenses you're preventing oxygen getting to the cornea. The longer this goes on, the thicker the cornea gets in response, until permanent damage is done.
Prevention: stay within wearing times and look after your CLs!
The major two which I believe you're hinting at are age related macular degeneration (where a layer beneath your retina starts to have a build up of waste products that then damages your light recepting cells) and the lack of accommodation that occurs when you get older and your lens loses the ability to bend as much so you need to hold things further away to be able to focus it. The latter is untreatable, but the former can be waylaid by eating lots of vegetables that are green. The biological chemicals in these help to prevent the build up of the waste products under the retina.
There are loads of other causes of deteriorating vision such as glaucoma which is characterized by a high pressure in the eyeball causing pressure on the optic nerve, but I fear I've rambled enough. Hope I've helped. |

I have just found I am suffering from something called glaucoma. This is where the pressure in the eye is not correct and can cause damage to the optic nerve.
I have started to lose my peripheral vision, but now it has been diagnosed I will at least not go blind.
It is important to have regular eye tests (which include a pressure test (just a little puff of air again the eye)) to ensure that you will not lose your sight. |

many reasons. sounds wierd but one is trying too hard and therefore straining....not just to see things but in other aspects of life. you probably dont understand what the **** i am on about and to be honest i dont really either but try and get hold of this book called "relearning to see" if you are genuinely interested it is an interesting book. by some guy called thomas quackenbush i think. it is about improving your vision naturally but it has a lot of other information about why eyesight gets worse in the first place etc. |

Age, some medical conditions. Visit the opticians and/or doctor regularly if you are worried about deterioration of vision. |
