Can Contact Lenses Fall Out Your Eye?


Can Contact Lenses fall out of your eyes?


With normal use, contact lenses will stay firmly in position. Soft contact lenses are particularly stable, and are unlikely to dislodge, even doing active sports.


However, they can come out under certain conditions. High winds can cause the eyes to water and cause the lens to move more, increasing the chance of lens loss. A sharp blow to the head may dislodge rigid gas permeable lenses. And rubbing your eye carelessly may result in a lost lens.


Describe to your eye care practitioner all of the circumstances in which you are likely to wear your contact lenses. This will help him or her prescribe a type of lens that is less likely to be dislodged given your activities.

Another Win For Science And Eyesight

Another Win For Science And Eyesight


People who have suffered damage to their eyesight due to exposure to bright lights may be able to have their vision restored using infrared light.

Research carried out in Australia on rats found that eye damage was reduced with exposure to infrared light.

But clinical trials will be needed to find out whether the treatment would also work on humans, ScienceAlert reported.

Dr Krisztina Valter of the ARC Centre of Excellence in Vision Science (ACEVS) and the Australian National University said that such damage could be caused to anyone who lives in areas with bright light or whose work exposes them to it.

The theory, explained by Dr Valter, is that infrared prompts more activity from enzymes in cells which enable the production of more energy.

As a result, oxygen stress caused by overexposure to bright light can be countered.

The ACEVS co-ordinates research going on in several Australian universities.

These are the universities of Sydney, Queensland and Western Australia, as well as the Australian National University.

Link between eye problems and lack of sleep, says study


Link between eye problems and lack of sleep, says study


A sleep disorder could not only make people tired in mind and body – it can affect their vision too, according to new analysis.

Obstructive sleep apnoea (OSA) is linked to high blood pressure, which in turn can affect the complex vascular system of the eye.

Examination of the results of several studies has led pulmonologist and sleep specialist Dr E Andrew Waller from the Mayo Clinic to draw up a list of eye complaints potentially caused by OSA.

These include floppy eyelid syndrome, glaucoma, non-arteritic anterior ischemic optic neuropathy and papilledema.

Mr Waller said: “The mechanisms that link these disorders is minimal.

“However, the recognition of these associations is important for primary care physicians, ophthalmologists and sleep physicians.”

He went on to say patients suffering from OSA should get regular eye examinations to monitor the potential onset of glaucoma.

People with OSA may find they wake several times during the night. The condition affects twice as many men than women.

How to Protect Kids Eyes This Summer



Ways to make sure children’s eyes are protected during the summer has been given by an American vision clinic.

The advice was given by the Vision Centre at the Children”s Hospital in Los Angeles.

As well as making sure children wear sunglasses, they should also make sure their eyes are protected if they play ball games.

Goggles should be worn if children play games such as tennis or baseball, according to the American Academy of Opthalmology.

In addition, goggles might be worn while swimming and the chlorine level should be checked.

It ought to be high enough to kill bacteria but not so strong as to irritate eyes.

Furthermore, if sand enters a child”s eyes, it should be washed out immediately with clean running water and the more tears produced, the better.

The child should not rub his or her eyes if this happens.

Close-Up Pictures of Eye’s


When you think of an eyeball, you probably think of a smooth marble-like sphere.

But these remarkable pictures seem less like a part of human anatomy and more like pitted cratered landscapes.

They show the complex and intricate textures hidden within the iris that give our eyes our unique and enchanting character

Computer games may improve sight

Computer games may improve sight


Adults who play action computer games may be able to improve a part of their vision known as contrast sensitivity, it has been found.
Researchers at the University of Rochester in the US looked at experts playing computer games that involved firing at targets.

According to the findings, which were published in Nature Neuroscience, the players had superior contract sensitivity to those who played other sorts of video games.
When the latter group played action games, their contrast sensitivity also got better, with improvements maintained for several months and, for some people, a matter of years.

Playing the action games made people better able to detect changes in shades of grey, even very subtle ones.
Another recent US study, reported by the Daily Express, found a link between use of mobile phones and computer games and visual-spatial skills in 12-year-olds.

Michigan State University”s research was part of a three-year scheme to look at how technology affects children in areas such as school and socialising.
