It's good to rest your eyes--at least try to take them out in the evenings.  I don't think it makes your vision worse, but it can affect your eye health as far as the cornea and infections etc. I haven't heard of the Renu problem, but there was a Bausch & Loumb recall.

if you become blind, you find darkness everywhere

I had a dream last night…\nPeople who become blind after the age of 6 can see in their dreams, whereas people who are born blind cannot.\n\nAlthough, people who lose their sight at 7+ have very vivid visual imagery in their dreams 20 or 30 years down the track. The content of their dreams is more often about familiar situations, rather than new ones.\n\nDreaming in sound…\nPeople who are born blind however, still dream. Their dreams, containing as much content as sighted people, are experienced by auditory imagery.\n\nThis is due to their lack of Rapid Eye Movement (or REM), which occurs in sighted dreamers, as if they are watching something in their dream. People who become blind, however have REMs of the same intensity as of sighted people.\n\n\nReferences:\nWebb, Jeremy 1995 The Last Word [Internet] London Reed Business Information Limited Available from http://www.newscientist.com/ [Accessed 22 June 2001]\n\nOrey, H (1999) Medi Info Source [Internet] Irvine, California CME Incorporated Available from http://www.medinfosource.com/expert/exp3092799c.html [Accessed 22 June 2001]\n\n\nWriter: Timothy, Camberwell Grammar\nEditor: Caryn Hamburger

I believe its because the photoreceptors and optic nerve are still being stimulated, similar to how your eyes get from a camera flash. The question is, how long does it last and can you still see these flashes at night or in a dark room?

They can attempt to inprove sight with a laser but there's no guarantee. What matters is the amount of damage that's already done. DON'T delay. Go to your doctor today! And good luck to you.

Poor night vision or poor adaptation to darkness is often a clinical sign of vitamin A deficiency and/or zinc deficiency.  How well are you eating?  Are you eating the recommended 5-9 servings of fresh fruits and vegetables and 3 servings of WHOLE grains each day?  Do you have any digestion or malabsorption problems?  Do you have obvious other health problems with your skin, hair, immune system, energy, etc.?\n\nVitamin A and Zinc deficiencies are fairly common because so many people today try to live on junk food diets.  If any of this 'sounds like you' it may be a good idea to see a nutrition-oriented health care professional for proper assessment and guidance.\n\nBest wishes.

I see them too in the dark.. and I have 20/20 vision so I don't think there is anything wrong with you unless it becomes prominate.\n\n\nAsk your family doctor it couldn't hurt. \n\nI always thought it was for this reason...... your eyes are made up of rods and cones that pick up light and color\n\nI see this as being similar to pixles on a tv\n\nour eyes have pixles so to say, and in the dark for our eyes to create the image, you get light and dark pixilation... just my opinion...\n\nwhen it's really dark I see static, not just black..... I know exactly what your talking about\n\n\nyour the first person who has ever said this

these particles are not really present in the light that you see. They are actually the nerves in your eye which are illuminated by the intensity of light. the same effects are not noticed when you look directly at a low intensity light(eg. Tubelight, zero watt bulb etc.)

i know Lazar eye surgery, but i don't know your full situation. go to other optometrists to get another opinion. ummm, carrots help your eyesight in the dark.. have fun, don't know much about this subject but good luck

It's all the carrots you've been eating.  Your night vision is getting better.  Don't worry if you turn orange, it is a harmless side effect. \n\nHave you seen my nocturnal friend?

Yes, it leads to blindness.  I can only see out of one eye now due to excessive consumption during my youth.  If only Yahoo Answers had existed then!

I have had that problem.  I asked my optometrist about it once.  They told me that it is normal.  It's a combination of a couple of factors:\n1.  Your eyes are trying to accomodate for the lack of light by adjusting to the dark.  This causes your pupils to dialate, which causes blood to flow more rapidly through your eyes, which over-stimulates the optic nerves.\n\n2.  Minor visual hallucination:  Your brain is trying to fill the void with images, trying to make sense of the newly-limited input filtering in.

No. Some people are color blind, meaning they see only black/white. Some people are blind, meaning they don't see anything at all. Some are synesthesic, seeing random colors/shapes for letters...etc.

You reminded me of my childhood days. I used to ask my father the same Questions.\n\nClouds don't go any where during night. They are still there it only that there is not enough light for us to see them. Remember when you see moon light we see those clouds around or sometimes the moon hiding behind the clouds.
