Vision (Definition)

Vision is a feature of a person's brain that allows him to see. He must have normal eyes, optic nerves (that stretch from the eyes to the back of his brain), and visual cortex (the vision center in the brain), in order to see properly. An ophthalmologist is a ...Read more

C.R.T. Is the contact lense you wear at night, then remove in the day to achieve 20/20 vision, does this work?

C.R.T. Is the contact lense you wear at night, then remove in the day to achieve 20/20 vision, does this work?

Sort of: These contacts are designed to change to shape of the eye while asleep. The change then reverts during the day. It is expensive and the vision varies during the day as the eye changes. A better answer is to just wear contact lenses during the day or get laser done. ...Read more

Why is my vision fuzzy when I am looking at the night sky?

Why is my vision fuzzy when I am looking at the night sky?

Less light.: At night your pupil dilates in an attempt to permit more light to enter your eye and impact your retina. The center of our vision is the macula where our more precise "cone" photoreceptors reside and permits us to see well in light. Our peripheral retina has less precise "rod" receptors that are more exposed at night when our pupil dilates. This is why your vision is "fuzzier" at night. ...Read more

Should I consider getting reflective contacts for night vision?

? Reflective: I am not aware of reflective contact lenses. There is also no such thing as contacts for night vision. Most people become a little nearsighted at night. Easier to just get glasses for night which have a mild myopic correction in them. ...Read more

What are the rods and cones functions in terms of night vision?

What are the rods and cones functions in terms of night vision?

Rods are for night: Cones detect color, and work best in bright light. The rods are the cells of the retina that function at night, allowing you so see better in dim light conditions. ...Read more

I wear glasses, sometimes I don't wear them, either way my vision at night time is wrose off then day time, does that mean anything?

I wear glasses, sometimes I don't wear them, either way my vision at night time is wrose off then day time, does that mean anything?

Night vision: Most people see worse at night than by day. This is common for a few reasons. For one, many people are more near-sighted at night, since it is harder to pick a point of focus. Also, at night people rely more on the rods than the cones in their eyes, and rods are not as good at perceiving sharp details. If you cannot see at all during the night, this might indicate a true eye disease... ...Read more

Lasik - night vision.?

Lasik - night vision.?

Some get glare: Some patients will notice glare or "haloes" around lights at night following lasik surgery. In the majority of cases, it is not severe and dissipates over several months following the procedure. Nearly all patients who have lasik are pleased that they did, although the displeased minority is very vocal in online communities. A prudent lasik surgeon will discuss these risks before the procedure. ...Read more

My vision is better at night, is this normal?

How can you improve your night vision?

Depends: For individuals with normal retinal function, there is, unfortunately, no way to develop superhero grade night vision. Conversely, for patients with decreased night vision or “nyctalopia”, as a result of dietary vitamin a deficiency, vitamin a supplementation will hopefully restore normal human grade night vision. Patients with degenerative conditions such as retinitis pigmentosa, unfortunately, lose night vision and peripheral vision from progressive photoreceptor loss. Patients with congenital stationary night blindness, cone/rod dystrophies and other degenerative disorders also have photoreceptor loss with loss of night vision. Although until now there hasn’t been much to offer these patients, research is currently underway investigating a large array of agents which may offer them some hope for the future. ...Read more

Can using sunglasses the whole day improve your vision during night?

Can using sunglasses the whole day improve your vision during night?

No: While wearing sunglasses on sunny days to protect your eyes is an excellent idea and will protect your eyes from uv rays, it will not actually "improve" your night vision. Protecting your eyes on sunny days may help with adapting to low light situations, but after 15-30 minutes you vision will have adapted sunglasses or not. Over the long term, not wearing sunglasses can cause some eye damage. ...Read more

I have very bad night vision, and anything that is lit. I've always been light sensitive. What could cause this?

Many causes!: Without an exam it is difficult to tell you what is going on. It sounds like you have always been this way, in which case it is 'normal for you'. Just like some people are cold sensitive (always need a sweater), some people are light sensitive. At the age of 48, you could also have early cataracts, which would decrease your night vision. ...Read more

Is it true that carrots help your night vision?

Depends: The basis for this "old wive's tale" is that, accurately, carrots as well as other yellow/orange vegetables and gourds (squash, pumpkin) are fantastic sources of vitamin a, an essential vitamin required for photoreceptor (cone/rod) metabolism. While severe vitamin a deficiency may lead to serious, but generally reversible, vision problems, such as night blindness, most people in developed countries meet more than their daily vitamin a requirements from normal diets and there is no need to consume exorbitant amounts of carrots. In fact, vitamin a excess may be toxic to the liver and some clinical studies have demonstrated that excess vitamin a metabolites may actually be potentially toxic to photoreceptors. ...Read more

Are there glasses that can increase your night vision?

Yes: In some patients adding a negative 1/2 diopter improves their night vision. Also night vision goggles can improve your vision at night. Spending several minutes in the dark, adapts your rods so you can see better. Use a red light flashlight to avoid loosing your dark adaptation. Don't forget that wild cats have 6 times better night vision than humans, so be careful out there. :). ...Read more
