If you don’t currently wear glasses or contact lenses, you might find that when you think of an eye test the picture conjured up in your mind is the card and chart of your school days. While eye tests when you were a child were great for identifying those who might need help in correcting problems with their vision, eye tests have come a long way since.
These days eyes tests combine traditional testing methods with new techniques and technologies to get an in-depth picture of the health of your eye. For those that do wear contacts or glasses, regular eye tests are essential for making sure that their prescription is up to date and best for their eyes. For those that don’t at the moment, tests can identify if there are any signs of weakness in the eyes.
While many people wouldn’t consider having an eye test unless they are having problems with their vision or are experiencing commonly known side effects such as headaches, eye tests are for much more than checking whether you are long or short sighted. Advances in technology mean that these tests can now help spot the warning signs for other aspects of eye health.
For example, an eye test will allow opticians to pick up on the early signs of eye diseases such as glaucoma and cataracts and can also be vital in the early detection of health problems such as diabetes or high blood pressure. This means that eye examinations are far more in-depth than ever before.
When you go for an eye test, you’ll find that your optometrist will be interested in much more than how clearly you can read the infamous letter chart. They will also compile a detailed history and details of your lifestyle, they will also use autorefraction to determine your baseline prescription and they will use tonometry to measure the pressure in your eyes – this is vital as it’s a key factor in identifying glaucoma.
Your optometrist will also conduct a slit lamp exam, allowing them to look at your cornea, conjunctiva, lids, iris and lens under high magnification with the help of a microscope and a small beam of light. They will also be examining the strength and flexibility of your eye muscles and carrying out a full retinal exam, to ensure that they have a broad and comprehensive picture of the health of your eyes.
A modern eye test may sound complicated, but your optometrist will talk you through the process and ensure that you get the best out of your exam.

The hardest part of relaxing is silencing the mind. Your thoughts move at a rapid pace and as your ‘to do’ list grows so do the racing thoughts. Shutting down the mind is tricky, but it is certainly possible. The key is to move all that energy stuck in the head down through the entire body and out through feet. May sound like rubbish, but it really works through a process known as ‘exhaling through the feet’.
Here’s how it works. Lie down on your back in a darkened room, works great just before bed. Imagine your breath moving from your lungs down through the entire body. As you exhale, picture the air moving down toward your toes. Picture your breath passing through every organ, heart, liver, kidneys, and continuing down the thighs, calves, ankles, and toes. Exhale completely, until all the air is out of your lungs and the next breath naturally comes. Inhale naturally, don‚Äôt force anything, and let your body do its own work. Once the lungs are full once again, start the process again of picturing the air moving through the body.
Repeat the process as many times as possible until you fall into a relaxing. The next morning you will feel refreshed and relaxed ready to face the world. A great night’s sleep is essential to decrease stress and strain therefore starting the day out right. Staying up late and waking up early, leaves us feeling dull most of the day. This can heavily impact various areas of your wellbeing. We are not as productive and the eyes are straining throughout the day. Plenty of rest, but not excessive amounts, starts the day out right and in a positive frame of mind. We will feel more productive and happy to get work done.
Learning to relax is an important habit to learn. As soon as you learn good relaxation methods, getting to sleep will come more naturally and you will notice huge changes throughout your life. Your mind, body and eyes will be eternally grateful.

Vision is a powerful technique which relies on the fact that all mental activity is accompanied by corresponding physical rehearsal. Thus if you imagine that you are speaking, or even if you frame your thoughts in terms of words rather than abstractions, there are minute but measurable movements of the vocal apparatus; if you imagine you are clenching or unclenching your fist, all the muscles involved undergo fractional changes of tension. When you see with your mind’s eye, the real eyes respond in a similar way, except that, as the eyes are even more intimately related to the mind than, say, the muscles of the arm, the changes are likely to be more pronounced. The advantage of mental seeing is that the mind’s eye has no refractive error and forms a model for the real eyes to emulate
According to the Bates hypothesis, faulty vision can arise as one result of emotional difficulties, among which may be a subconscious desire not to see. As far as refractive error is concerned, this desire not to see can be compared to the desire not to walk or talk shown in certain kinds of hysterical illness. The brain is able to block the responses of the body so that walking or talking-or focusing-do indeed become more difficult, or even impossible.
The brain can also block the visual process in another way, by erecting a barrier of some sort between the unconscious and the conscious mind, so that, even if the eyes are performing well, the signals are obstructed or degraded before being allowed to reach the consciousness.
It is helpful to think of this barrier in symbolic terms, as being made of some substance which can vary in consistence according to the subconscious wishes of the brain. When vision is perfect the substance of the barrier is perfectly fluid and the signals pass through it freely, but as vision deteriorates the substance becomes more and more glutinous, slowing down the passage of signals or preventing it altogether.
There are two distinct ways in which the brain can block the visual process. The first is by interfering with the mechanics of vision; the second is by altering the ‘consistency’ of the barrier between the unconscious and the conscious mind.
The brain and the eyes work closely as a team. The eyes have to first capture an image and focus on the shape, size, and colors. The mind needs to interpret that information which is seen and then store it for recall later. Images that we see daily take mere seconds to interpret and remember. New images take a little bit longer. The more focused the eyes are on an image the more strong the memory will become. When looking at new object, pay attention to the lines around it, the borders, colors, size, shape, and anything else that will make recall easier later. Of course, the more relaxed the eyes are the quicker the mind can process and memorize new objects.
Concentrating too hard or focusing on images that doesn’t interest us causes unneeded strain and it will be difficult to remember them later. In order to maximize the memory, the image must first be viewed in a calm and relaxed manner. Below is a short exercise to try in order to get the mind and eyes to relax and work together properly.
First find a comfortable position, this could be sitting in your favorite chair or lying on the floor. Whichever your preference, make sure the spine is straight and the hands are relaxed at your side. Next, close your eyes and picture the number 5 down to 0 in your mind. Exhaling, really see the 5 in your mind. Let the eyes follow the black lines of the 5 and really picture the number. Relax and exhale completely by letting all the air out of your lungs until you naturally take the next breath.
Allow the lungs to fill completely with air and then picture the number 4. Again, picture the number completely while you exhale. Really see the lines, the black color, the shape; don’t stop picturing the number until all the air has left your lungs and the next breath comes naturally. Do this all the way down to 0.
In time you should be able to visualize images in the mind more clearly and feel more relaxed in the processed.

LASEK which is an acronym for Laser Assisted Sub-Epithelial Keratomileusis is one of the younger techniques for executing eye surgery and rectification of vision.
LASEK as an surgical procedure is worthy for all of those that can not get the more frequent surgery, LASIK, because of several grounds, including to fragile cornea or too straight cornea. External factors, such as line of work may play a role in the selection of surgical process method. For instance, athletes and airplane pilots may fair better without a flap in their cornea.
If you want to do an LASEK surgical procedure on your eyes you are most likely above 18 years old, or that your prescription glasses or contacts hasn’t varied for at least a year. If that is the case, anyone with Myopia (short-sight), Hyperopia (long-sight) or Astigmatism can do the the surgical procedure.
Before we go through the how you eye function. Our eyes are very much dependant on light. If there wasn’t some light you would not be able to visualize at all. When the light rays hit our eyes of the outside cornea it is bend, or refracted so that it becomes adjusted on the inside and back of the eye, the retina. The retina is where the “picture” is created and where the optic nerve pick up the picture and transmit it to the mind where we “see” it.
If you have any kind of the above named vision problems the flexing, or refraction of light is the problem that causes you vision to go bad. The light rays become cracked and the picture on the optical nerve go out of of focus.
Omitting any pre- and post examinations the following will in a great sense deal with how a LASEK process is executed.
To commence you will have anesthetic drops in your eyes to take away any pain during the surgical process. Next, an lid speculum is attached to the eyelids to hold them apart through surgical process and so that the doctor doing the surgery may have full access to the eye during the procedure.
Next, a tiny retinal cone is placed on your eyes outer surface off the cornea. In this retinal cone a few drops of a mild alcohol solution is dropped. This alcohol softens the outer layer of the cornea. Within second the doctor then removes the alcohol and the area is rinsed in good order. The doctor may now take away the outer surface of the cornea and reveal the central cornea layer, called the stroma. As you can read from the description no cutting tools is used around your eye during the procedure. The outer surface of the cornea is just lifted back once the operation is finished.
The next stage of of the operation is when the laser is employed. In nearly every surgery a special laser is applied, called the Excimer laser. This laser will send pulsations of UV-light into the eye. This UV-light is used to evaporate enough of the central cornea layer to remold it as much as needed to rectify the vision.
When the laser has completed its job the cornea surface is put back and a protecting bandage lens is put in to protect the initial healing period. This lens is taken away inside a few days, and inside a workweek, or two you are able to drive and work again.

One of the best ways to improve your eyesight and improve your eye health is to simply relax – relax your body, relax your mind, and relax your eyes and eye muscles. Best times to try to relax your eyes are first thing in the morning when you wakeup, and at night just before you fall sleep in bed. Keep your eyes closed, and try covering your eyes up with a blanket to increase the darkness – the darker it is, the more relaxed you will be. Think pleasant thoughts, and picture pleasant sceneries or things that you like. This helps you relax your mind and relax your eyes.
Concentrate on relaxing your eyes. You’ll immediately feel more relaxed overall – relax your eyes, eye muscles, and the muscles around your eyes. You will feel less tense, and feel more calm when you relax your eyes. Also try taking deep breathes. There are also various exercises that you can do to help you improve your eyesight. When performing eye exercises you should take off your glasses.
Start by limiting your use of your eyeglasses or contact lenses. Only use them when they’re absolutely necessary, such as for reading or for doing essential work, and driving. Glasses and contact lenses are crutches, and if you keep on wearing them, you will not be able to improve your eyesight. You can try using pinhole glasses, which are made from an opaque sheet of plastic lined with pinhole sized openings. These tiny holes on the glasses allow a narrow beam of light to enter the eye, which reduces the circle of confusion on the retina, resulting in clearer images. Using Pinhole glasses can help improve your vision while you are using them, reducing your dependence on corrective lenses.
Avoid squinting your eyes to try to focus better. Squinting your eyes places additional strain on your eyes, and this is something you want to avoid. Remember to blink often and keep your eyes moisturized. A dry and irritated eye does nothing to help your eyesight, and only further increases the strain and stress on your eyes.
The next time you find yourself staring and fixating on your computer screen for too long, remember to take a little time off and relax your eyes. Take away your focus from the monitor and look outside your window; try doing a short period of palming; or simply close your eyes and picture pleasant things.
Learn how you can naturally improve your eyesight, and begin to see better.
