Question 1

how do i improve my vision?

Accepted Answer

Depends: If the vision is diminished by a need for glasses, then get them or contacts.  If there is disease, the it should be treated.  Some things cannot be treated like neglected disease or hereditary problems.  See your ophthalmologist for a diagnosis.

Question 2

what does 20-40 vision mean?

Accepted Answer

Answer: 20/20 means you see at 20 feet what others see at 20 feet. This is normal vision. 20/40 means you see at 20 feet what other can see at 40 feet. Vision is mildly blurred. Hope this helps.

Question 3

what is your non-vision time?

Accepted Answer

?????: I have never heard of this term but i guess it refers to periods without visual input (ie when eye are closed or during sleep).

Question 4

is 20/30 and 20/40 vision bad?

Accepted Answer

Depends: These are levels of vision that still indicate good and useful vision.  If you are used to 20/20 vision and you have a drops to 20/30 or 20/40 (uncorrectable) then it may seem bad to you.  In my state of washington, the break point for a driver's license is a vision level of 20/40, so the state does not consider this 'bad'.

Question 5

how can we protect our vision?

Accepted Answer

Eating right: Eating right is a great start!  reporting any changes in our vision to our primary care physicians is another step in maintain healthy eyes.

Question 6

can a cold affect one's vision?

Accepted Answer

Yes it can: Cold and sinus congestion can affect vision but it only lastsas long as the congestion lasts.

Question 7

i've 20-60 vision. what is that?

Accepted Answer

Lowered vision: If your 20/60 vision is best corrected, then there is some problem with your eye which limits the best acuity.  If it is the best uncorrected, there may be some improvement even to normal with eyeglasses.  The fraction 20/20 indicates the smallest print that can be seen at 20 feet while 20/60 means the normal can see them at 60 feet.

Question 8

can you tell me how vision work?

Accepted Answer

Complicated: An image is focused by the eye on the retina which translates the light into an electrical signal conveying the shape, color and other features of the image to the occipital lobe of the brain.  This part of the brain converts that signal into the picture that we call  vision.  A book has been written on each step in the sequence as it is very complicated.

Question 9

is it possible to improve vision?

Accepted Answer

Yes: There are ways to improve your vision from dietary and vitamin supplements, to corrective lenses, to laser surgery, to implantable lenses. Many options can be specific to your needs or particular problem. Follow with an eye doctor for evaluation.

Question 10

what can cause my vision to blur?

Accepted Answer

More specific: How long does it stay blurry? Any medications?  Very common reasons are dry eyes and nearsighted/farsighted/astigmatism errors.  A good eye exam by an ophthalmologist can provide a more specific solution.
