When it comes to caring for your eyes and eyesight, regular visits to a good eye doctor are essential. An eye test every 2 years is a good idea.

During those check-ups, the eye doctor will examine your eyes not only for acuity of vision, but also for early signs of certain eye problems which can creep up on us quietly and steal our eyesight. As we approach the age of 40, it’s time to pay more attention to these possibilities.

Here are some eye diseases to ask about.


Ask your eye doctor for a glaucoma pressure test.

Glaucoma is the name for a group of eye conditions related to the pressure inside the eyeball (intraocular pressure). Our eyes need a certain amount of pressure to work correctly, but in glaucoma, that pressure is increased.

The higher pressure causes no discomfort or pain

Without a pressure test done by an eye doctor, we wouldn’t know the pressure had increased. But it works silently to damage the optic nerve, where it leaves the eyeball to carry visual information to our brain.

What increases the intraocular pressure in glaucoma is blocked drainage.

Normally, the eye fluid (aqueous fluid, unrelated to tears) can drain from the eye back into the bloodstream by seeping through tiny channels in the inside corners of the eyes.

As fluid is created, some drains out, keeping the intraocular pressure even and steady.

When the aqueous fluid is blocked from draining out enough to balance the new fluid being created, the intraocular pressure rises, progressively damaging the optic nerve, and causing us to gradually become blind.

Detached retina

Ask for a full eye examination to check on the condition of the retina.

Our eyes are like little cameras and the retina is like the film. It’s the inside back surface of the eye, where images are formed of what we see, and are then transmitted as electrical activity to the brain, by the optic nerve.

If the retina is at all weakened, for example by a little hole or tear, then gradually the eye fluid (intraocular fluid) can leak underneath it and cause it to peel off.

When it’s not smoothly lining the back of the eyeball, it stops functioning well as the film in this little camera. Images deposited on it are now blurry or dim.

Aside from blurriness, you might notice

A shadow encroaching on your vision on one side;

Occasional bright flashes; and/or

Showers of dark spots (floaters).

If these symptoms become more severe and you notice any diminishing of your vision, see an eye doctor immediately, to avoid progressive damage to your eyesight.

This condition can be treated, either by a laser or a freezing treatment, if it’s caught early enough. If not, surgery under general anesthesia will be needed.


Ask what might be the cause of your visual symptoms.

Just as a camera has a lens which focuses light onto the film, so our eyes have a lens which focuses light onto the retina at the back of the eye.

Sometimes, most often as we age, the lens can become cloudy. This will impair our vision, and cleaning our glasses will be of no help.


Lights may become too bright, dazzling you

Colors may start looking faded

Things may look misty or dim

If you find that you?re having trouble with driving, reading, using the computer, or any other activities that require good visual acuity, see an eye doctor without delay.


Ask what’s causing this inflammation in your eyes and whether it can be cured.

The uvea is the middle layer of tissue around our eyeball, with the outer layer being the sclera (including the cornea), and the inner layer the retina, which is at the back, but also curves around towards the front of the eye.

The uvea can become inflamed in a number of ways that are different in each individual. There are many causes for it, many ways it can affect other parts of the eye, and some other conditions in the body that it can relate to.

The term intraocular inflammation is used to include all the variations. There are many tests that your eye doctor could run, depending on how the uveitis appears in your case.

Treatment goals

If there’s pain or discomfort, to relieve it

Preventing loss of eyesight

To address the cause, if that’s possible

Your eye doctor may prescribe some type of eye drops, or corticosteriods, or some newer drug. Once it occurs, uveitis tends to stay, and must be controlled when it can?t be cured.

Independent driving: new element of driving test- feasibility and information

Independent driving element in driving test will come in effect from Oct 2010.

  • What is an independent <a…


Independent driving element in driving test will come in effect from Oct 2010.

Independent driving is tasking the candidate to drive for approximately 10 mins either following a series of directions, following traffic signs, or a combination of both.

Independent driving is when the learner get out on the road He/She will be driving alone and they need to know how to drive safely. Simultaneously it is very important for a learner to look at the signs at the time of driving because that’s in normal life what the learners are going to do. It actually puts theory test and practical test together. It makes you think about the signs, makes you think independently and makes you feel much more confident.

  • Why independent driving will be introduced:

“The feasibility of introducing independent driving into the GB driving test” was studied and according to it, there are few situations which demand this element in driving test.

Statistics on the accident risk of new drivers shows that after passing their test they are at their peak in terms of their risk of having an accident. A number of reviews have concluded that traditional driver training does not seem to have any positive effect on road safety in terms of accident reductions.

One interpretation of these findings is that the experience gained by drivers after passing their test is completely unlike the experience they gain Pre-Test. Findings from qualitative research on the perceptions of new drivers seems to support this; in focus groups learner drivers expressed their belief that ?real driving’ is fundamentally different from the training required to pass the driving test.

A number of authors have suggested however that driver training should not only focus on vehicle control skills but also on factors that have been shown to be related to accident reductions, according to the research evidence. This includes higher perceptual skills such as

  • Hazard perception
  • Safer attitudes towards risk
  • Better self-awareness of one’s driving ability.

Post-Test experience seems crucial for reducing accident liability, it is theoretically possible that if the relevant elements of post-test experience can be identified and trained pre-test then driver training may be better placed that it is currently to reduce post-test accident risk. An existing example of this approach in GB driver training is the introduction of a video-based measure of hazard perception skill in 2002 as part of the driving theory test.

Once learner passes the test, the thing they struggle to deal with is not having the person sitting next to them to guide them around when they need it. Sudden introduction of the extra elements of having to read traffic signs, road markings, or possibly having passengers or music in the car, made it more difficult for learner.

Possible solutions for safer new drivers may be a ?

  • Tracker fitted to their vehicle to monitor speed
  • Vehicle handling
  • Maybe reducing insurance costs
  • Limit passengers
  • Plates compulsory
  • Limit engine size
  • 40 hours supervised driving
  • Compulsory pass plus or motorway driving.

All for the first 2 years they are insured, not from when the test is passed.

  • Independent driving test examination:

On the independent driving test you have to do two maneuvers. However, when the new test starts, you may only have to do ONE maneuver. The test duration may also be increased to allow extra time for Independent Driving, and this will result in an increase in the test fee. You will still need to practice all the maneuvers because the Examiner on the day will decide which one you should do.

The whole thrust of independent driving is to prepare yourself for the real world.

Spooky Creatures: Something out of ‘Alien’

Something out of ‘Alien’: Rare frilled shark caught off Australian coast
(CNN) It looks like something out of “Alien” but has more in common with “Jurassic Park.”
It’s a rare frilled shark that has been caught by a fisherman in Australia, where no one remembers ever seeing one caught before.
With a mouth packed full of needle-like teeth and a body like an eel’s, the 6-foot-long frilled shark is sometimes described as a fish “fossil” that dates back 80 million years.
David Guillot says that it’s like nothing he or his fellow fisherman have ever seen in the deep waters in Australia’s southwest.
“It was really prehistoric-looking, freaky really,” Guillot said.
He caught the fish while trawling for fish at 1,100 meters a week ago and thought he might have discovered some new type of shark.
“I’ve been fishing 30 years and never saw anything like it. So I brought it in,” he said by phone from his boat Thursday. “Honestly, we thought we had caught a brand new species, maybe discovered something wild.”
