Are you holding the newspaper farther away from your eyes than you used to? Join the crowd—age can bring changes that affect your eyesight. Some changes are more serious than others, but for many problems, there are things you can do to protect your vision. The key is to have regular eye exams so you can spot problems early.SEE VIDEO BY TOPIC: The Highly Sensitive Man

A few years ago, the artist Concetta Antico discovered that she was carrying a genetic mutation that gave her astonishingly sensitive perception of colour — seeing a spectrum of distinct shades where we only see one.
As she told BBC Future in , even the dullest pebble on the road shimmered like a kaleidoscope. A seemingly plain green leaf may burst with vivid red shades, while a punnet of tomatoes is a multi-coloured palette of tones — Antico claims she can pick out the ripest fruit at a glance, thanks to subtle differences in its shade that would be invisible to most of us.
In the same way that a colour blind person cannot imagine the variety of reds and greens that most people can see, most of us may not be able to picture the rainbow she is describing. The detailed colour in Concetta Antico's artwork may help us to imagine what she sees Credit: Concetta Antico.
It had long been known that people with extraordinary vision like Antico should in theory exist, thanks to an unusual difference in the way their eye is constructed. Imagine the retina as a kind of mosaic, composed of different kinds of light-sensitive cells known as cones.
The light from each part of a scene will activate these cells to different degrees, with the exact combination of signals determining the colour we perceive. Thanks to two different mutations on each of the X chromosomes, they have four cones — increasing the combination of colours they should be able to see. Then Antico came along, passing a string of tests that showed her vision was different.
Studies proved that her tetrachromacy gave her enhanced vision in low lighting — allowing her to see astonishingly vivid scenes at dusk, for instance. Even if you carry the right versions of the genes involved in colour perception, training may be crucial to cash in on your genetic potential Credit: Getty Images. Even so, many questions remained. Given that many women may be carrying the mutation, why do so few people prove to have such astonishing vision, for instance?
Antico is an artist, who has paid close attention to subtle variations in colour for almost all of her life. Sure enough, Antico proved to be more sensitive than the average person, particularly when looking at reddish tones — a finding that perfectly matched the predictions from her genetic test. As Jameson had suspected, Antico also performed much better than the other potential tetrachromat who was not an artist — supporting the idea that her colour training had been crucial for the development of her abilities.
Jameson's experiments allow her to simulate Antico's vision. The black dots reveal the areas affected by her extra "cone" - about a third of the image Credit: Kimberly Jameson. Using these results, Jameson then reconstructed some photos to give us a better idea of the way the world may look to Antico. Although it would be impossible to recreate the exact picture she sees, the photos highlight which areas would be most sensitive to Antico; in the scene above, for instance, the highlighted patches show the areas most affected by her tetrachromacy.
When I ask her what the scene would look like in her eyes, she says the hillsides are orangey pink, while there tends to be a lot of violet in the deadwood. So far, it looks like Antico's paintings show the same kinds of details that might be predicted by Jameson and Winkler's simulations.

Age sometimes brings changes that weaken your vision and eyes, but there are things you can do to maintain lifelong eye and overall health. The solution may be as simple as using brighter lights around the house to help prevent accidents caused by weak eyesight or seeing your doctor more frequently to screen for age-related diseases. While eye problems and eye diseases become more prevalent with age, many can be prevented or corrected if you:. These are several eye problems that are more common as people age, but they can affect anyone.
Adult Vision: 19 to 40 Years of Age
Rare, inherited vision disorder in which a person has little or no ability to see color. People with achromatopsia also commonly experience some vision loss, especially in bright light, to which they are extremely sensitive. The severity of achromatopsia varies. Although there is no cure or treatment for this disorder, people with achromatopsia can manage its symptoms. For example, they can wear sunglasses or tinted contact lenses to cope with bright light. They can use magnifiers and other devices for low vision to help them read, and telescopes to help them see distant objects. Acute zonal occult outer retinopathy AZOOR is a retinal disease characterized by sudden onset of flashing lights and visual field changes in an individual with a normal retinal exam. It affects women 3 times more frequently than men; most people affected are Caucasian, middle-aged, and myopic.

Guys' eyes are more sensitive to small details and moving objects, while women are more perceptive to color changes, according to a new vision study that suggests men and women actually do see things differently. Research has shown women have more sensitive ears and sniffers than men. In one part of the study, the researchers asked the volunteers to describe different colors shown to them. They found that the guys required a slightly longer wavelength of a color to experience the same shade as women and the men were less able to tell the difference between hues. The researchers also showed the participants images made up of light and dark bars that varied in width and alternated in color so that they appeared to flicker, a measure of participants' sensitivity to contrast. Compared with the women, the male volunteers were better able to identify the more rapidly changing images made up of thinner bars, the researchers said.
Vision changes occur as you get older, but these changes don't have to affect your lifestyle. Knowing what to expect and when to seek professional care can help you safeguard your vision. As you reach your 60s and beyond, you need to be aware of the warning signs of age-related eye health problems that could cause vision loss.
Light sensitivity is also called photophobia. It is a common experience with many underlying causes. The broad term covers many kinds of discomfort in bright light, ranging from trouble adjusting to brighter light to pain in the eyes. Learn More.
