Did you know that the aviator sunglasses which are also know as pilot shades, have been around for quite some time now? In fact, they have been around ever since the 1930’s. The evidence for the same can be seen in some of the movies of olden days.

These aviator shades were very comfortable to wear and also protected the pilots from the dangerous rays of the sun especially during their high-air flight missions. These lenses were very durable and impact proof as well.
The basic design of these pilot shades haven’t changed a great deal which is evidently seen even today. The design of the pilot shades were fundamentally based off goggles that were used by the U.S. Military during the early days. In fact, even today, pilots from world over are been recommended to use a pair of aviator sunglasses for men, not merely for its comfortability, but also for its ability to guard the pilots’ eyes from the dangerous rays of the sun.

If you dream of freedom from glasses or contact lenses laser vision correction may be the solution for you. LASIK is the most well-known vision correction procedure, but there are several other types of laser vision correction. By reshaping your cornea, your ophthalmologist can correct nearsightedness, farsightedness, and astigmatism, giving you clear vision without the hassle of corrective lenses.
Refractive Error
Nearsightedness (myopia), farsightedness (hyperopia), and astigmatism are all forms of refractive error. Your cornea bends, or refracts, light to focus on the retina. When your cornea is misshapen the light does not focus properly. Refractive surgery reshapes your cornea, correcting how the light is bent and therefore correcting the focus of the light on the retina.
Types of Laser Vision Correction
You have probably heard of LASIK, but might not be aware that there are two types of LASIK, traditional and custom, and that there are several other forms of laser vision correction including:
- Epi-LASIK
- iLASIK
- LASEK
- InterLase
- PRK
All are performed using an excimer laser. The technique is different for each type of laser surgery, making laser vision correction possible for people who are not good candidates for LASIK.
The Precision of Today’s Laser Vision Correction
Refractive surgery is not new, but it is being constantly improved. Traditional LASIK has been used to safely and effectively correct vision for over twenty years. Custom LASIK is far more precise, and can give you even clearer vision.
In custom LASIK, Wavefront technology is used to map your eyes and guide the laser. Wavefront is also used to guide other types of laser vision correction. Wavefront diagnosis helps your ophthalmologist determine which type of laser surgery is right for you, and can detect high order aberrations that can be made worse by LASIK surgery.
Improving Your Vision and Your Life
Laser vision correction can mean freedom from corrective lenses for many patients. Those with very poor vision can achieve better corrected vision. Improving your eyesight can open up opportunities that you never had before. It may simply make things like swimming and other hobbies easier and more fun. For some, it can make essential activities, such as driving, possible. Getting rid of your glasses or contacts means waking up each morning with clear vision and never again having to worry about losing or damaging your lenses.

There’s a reason why school desks used to be slanted back in the old days. Unfortunately, most of today’s classrooms seem to have forgotten what that reason is. Educators recognized a long time ago the benefits of using a slanted surface to read and write. Slanted surfaces make both activities easier for students, facilitating learning and preventing posture and vision problems. It is all based on ergonomics, the science of designing work and learning equipment and environments so that they fit human beings in a way that is optimal both to the health of the worker/student as well as his or her productivity/learning ability.
In terms of reading and writing, the ergonomics of slanted surfaces is based on the simple fact that, when we are reading, we have a natural tendency to tilt the material towards us. It is more comfortable to have material slanted towards you. Using a slanted writing and reading surface automatically lets the letters on the page come into focus better without needing to strain you eyes. It also lets you track lines with greater ease and keeps letters and numbers in a consistent perspective as you make your way down the page.
The result of all these factors is that your brain doesn’t have to work as hard at interpreting the written symbols, thus leaving it with more resources to actually comprehend, learn and analyze what it has just read. This also means you are less mentally fatigued by the end of a reading/study/writing session.
Buy a whiteboard. Reading and writing slant boards being sold today are created with the intent of providing students and people in general with an optimal environment in which to work and study. Pioneering studies, the results of which have been published in scientific journals like the American Journal of Optometry Archive, have shown that there is a strong relationship between a person’s learning/working efficiency and his/her posture, work distance and work surface.
Learning performance improves especially when the right conditions are established during near-point visual activities, i.e. reading and writing. To this end, the optimal angle for reading and writing surfaces has been found to be between 20 and 23 degrees, with the person sitting at a fist-to-elbow distance from the working surface.
Adjustable slant boards let you find your optimal angle. Many slant boards also come with additional built-in features like a whiteboard, so that you won’t need to buy a whiteboards separately. A proper reading and writing set-up will help reduce your heart rate, help you maintain a better breathing pattern and reduce neck and body tension by compelling you to sit using proper posture.

Many recent studies are showing how omega 3 and retina health can be maximized by a daily fish oil supplement containing high amounts of DHA fatty acids. Age related eye disease can be slowed or even halted by this natural substance, as long as you select carefully.
It is known that omega 3 fatty acids, and particularly DHA, play an important role in the layer of nerve cells in the retina, being a significant part of the human brain and central nervous system as well.
The US National Eye Institute says that omega 3 reduces the risk of age related blindness by over 30% in a recent study and found that that it helps the eyes by acting as an anti-inflammatory, one of the key features of any good fish oil.
The problem is how to get the most DHA as most oils today contain far more of the less useful EPA. To get the maximum omega 3 and retina benefits you need to know how to find the right fish oil supplements as many offer little or no benefits.
The DHA level is crucial as this fatty acid provides most of the benefits, not only for your vision but for many other ailments too like heart disease and brain health.
Look to get at least 250mg of DHA per capsule with a 2:1 ratio of DHA to EPA to reap the maximum rewards.
The purity of any oil will also determine how successful it is and any oil you select should have undergone molecular distillation to remove the harmful toxins like mercury and lead. Pure oil will also eradicate any of those fishy burps you may have experienced before!
One of the best fish for this purpose is the New Zealand Hoki as it’s very high naturally in DHA and low in contamination, coming from one of the cleanest oceans on earth.
Now you know the best omega 3 for retina health you can help to protect your vision from future problems or substantially reduce the symptoms if you currently have any vision issues.

There are ways to improve your vision naturally, simple techniques and exercises that you can learn easily enough, that can be added to your everyday routines. Fortunately they are easy to do and can have a very positive effect on your overall well being as your eyesight improves.
Too many people today are depending on glasses or contact lenses to improve their vision to see clearly and there are a large number of people who are resorting to Lasik surgery to permanently improve their vision. It wasn’t always that way; One hundred years ago about 10 percent of the population in the USA wore glasses, today the number is over 50 percent.
We know a lot has changed over the past 100 years, everyday life in general has become more stressful and eye strain is more common because of the close up and detail work that we do. Even the invention of electricity and advanced technology plays a part as we read and use our computers all hours of the day and night, and street lights make the roads safe to drive at night but the glare from them and oncoming headlights can cause fatigue and eyestrain.
The eye functions in part because of the actions of the eye muscles’ and like all muscles of the body they can be strained and damaged by overuse and repetitive actions. This is why it is important that we relax and exercise the eyes and their muscles.
Some Techniques to See Better Naturally
First is the DOT exercise. You can do this one now. Find a period or comma in the text you are reading and bring it into focus as clearly as possible. It will probably become blurry as you do this.
Next close your eyes and let them relax. Deep breathing can help here as you concentrate on relaxing your eyes. After a minute open your eyes and look again at the period without straining and let your eyes move around the page, over and around the period. Blink occasionally to keep your eyes moist.
Next close your eyes and picture the dot and then look again at it. As the eyes become relaxed it should be easier to see the dot.
Second is the WORD exercise. Find a word on the page that is five or more letters long and without moving your eyes stare at the word so that all letters are in view. Focus on the entire word and create an image in your head. Again it will become blurry as you concentrate.
Now relax your eyes and let them move over the page naturally, all around the word and not forcing them to look at what you want. When you do look at the word it should be clearer. Letting the eyes move around will help them to work better without the strain.
Third exercise is the DOUBLE VISION exercise. Most people have a dominant eye and use it to look at an object while the other eye does its own thing. This exercise will help them to work together as a team.
Relax your eyes and focus on the object in a calm way. By crossing the eyes you will see two images, try to focus in on each and slowly bring them together and focus on the one image. The trick here is to be relaxed and to do this calmly.
These are just a few of the many exercises that you can begin doing daily to help you to see better naturally. It is not impossible to see significant improvement in your vision after taking part in a daily program of exercise and relaxation techniques. You can lose your glasses forever.
