Contact lenses and dry eyes

Often contact lenses can cause dry eye syndrome. Itchy eyes and feel irritated and wear contact lenses is very unpleasant. However, the true subject of this article is on the opposite side. Contact lenses can also help prevent the eye from drying out. Why is it that you ask. If you have severe dry eye, some contact marks to) help the eyes to the issue of drying b) of some gel from its inner surface until it stopsWatching, and then refreshes the eye and wet. Wet perhaps the wrong word, since we are talking about dry eyes, but in comparison, wants to feel like the eye, without being useless, wet is a good view.

I wear contact lenses since 1997 and recently I discovered the hard way that I actually suffer from dry eye syndrome. I had this character before, but never put the dots together until now. What had happened was that I really lost my left eye contusion. After 10Day started the eye is still very red and itch. I made an appointment with my eye doctor to have occurred, according to the eye. I had my glasses and that day my eyes were really bad when I arrived for my appointment in late afternoon. The ophthalmologist checked my eyes and saw the severe drought. He came to my table and asked me some questions. Then he returned with the following statement.

First, my left eye was OK. Was full of bruises, butotherwise OK () next to the drought. But it also has severe dry eye and certainly explained to me how the contacts that I use to effectively protect the eyes from drying out too much. And when he explained the details to me is suddenly made everything much more sense. So I went home and although it was late in the afternoon I replaced the contacts and glasses in an hour my eyes were actually much better.

So if you suffer from dry eyes, which I recommend you speak, your ophthalmologist.A combination of special contact lenses and eye connectors, you can significantly reduce symptoms of dry eye. It may take a couple of weeks before seeing results - depending on the situation. Kindled in my case if I contact I saw an improvement within 7 days.

Anti-reflective Lens Coatings - Pros and Cons

Anti-reflective coating: Not a clearer picture?

Anti-reflective coatings to reduce unwanted reflections from surfaces and are often at stake, photographic and optical lenses used instrument. Reflections are a problem for those wearing glasses. Power-rings, which are particularly evident in lower targets by multiple reflections on the lens surface. If these are reduced by external and internal reflection, light transmission isincreased, becoming clearer. Reflection reduced also reduces glare and 'ghosting', with night driving or working at the computer screen, greatly reduces eye fatigue will be observed. Aesthetically speaking, an anti-reflective coating allows a wearer's eye and face are most clearly seen by an observer.

In the Beginning

The basic principle of an anti-reflective layer is called "destructive interference". Antiglareare possible because the light as a wave, and we rely on the use of the technique of destructive interference. If the coating thickness is a quarter wavelength, the reflection from the front and rear of the coating is out of phase with each other cancel each other out, then, and there is no reflection visible.

For an anti-reflective coating to work, the index of refraction of the coating material must be equal to the square root of the lens refractiveMaterial. Anti-reflective coatings are particularly suited to high index lenses.

Cons

One of the main complaints of wearing glasses on the anti-reflective coatings is that they are difficult to keep clean. However, they are not aware that without the coating, which effectively masks unwanted reflections dirt, stains or smudges on the lens.

This is also the case of scratches that become clearer on an anti-reflective lens coating. The scratch is naturallybe cleaned frequently or, so it is important not to dry with a paper towel or shirt to clean the lenses, especially if it is in shadow.

Pro

Reflective coatings today for the most part, an additional hydrophobic coating that repels water and grease. This marking will be spraying water, and avoid a reduction in the static structure, makes them easier to clean.

The advantages of the "new" anti-reflective coatings are:

Easy to clean
Scratchresistant
Durability
HEAT RESISTANCE
Visual Clarity
Cosmetics (lenses look invisible - such as TV presenters)
Better transmission of light during night driving aids

Color lens manufacturers are aware of the problem and try to find contacts of living color, but of course.

Acuvue 2 color opaque
FreshLook ColorBlends

If this is your first time with colored contact lenses and are not sure what effect you want, start with the lenses to improve. In this way, yourFriends will notice that you look more attractive, but probably will not notice what it is that draws your attention to himself.

Contact lenses for dark eyes

If you have very dark eyes and tried color contact lenses a few years ago, probably were not very enthusiastic, with the effect. Contacts of the previous generation did not look right. However, recently developed color lenses like Freshlook ColorBlends can do wonders for dark eyes.

One thingDo not forget, however, is that enhancers do not work on brown eyes, so that is the only choice of opaque lenses. Acuvue 2 Colors opaques and Freshlook ColorBlends work best for dark eyes.

Also, you should be careful in choosing colors. Should be a color that would look right with your skin and hair. See table color contact lenses with tips and photos.

If you just want to make your eyes appear brighter and more alive, not their color, go for brown or tanSlow. In this way, your eyes will not see a different color, but people is that they are bright and vivid.

At the same person, blue from Acuvue would look very different from Freshlook blue. A lot depends on your eyes and face,It is almost impossible to predict the outcome until you wear your color contacts.

Do not pay too much attention to how the lens appears in the picture, because on you will probably look different. This usually happens with lenses Enhancer - enhancers blue on blue eyes look very different from enhancers more gray eyes. Opaque colored contact lenses may look very different on different people, this is not because of your natural eye color, but because of the shape of the eyes, skin and hairTypes.

If your small selection of produce a color, I would recommend that you ask your doctor for two prescriptions: one for Acuvue 2 colors, and another for Freshlook. So for both. They taste much the same way, so if you would spend no more than 2 boxes of each order.

Then, after wearing your new color contacts for a while ', you can decide for yourself what looks best.

Furthermore, doctors usually give you color contacts free trial. You can not really bring in publicStudy, lenses, because the word "test" imprinted on it, but it gives you an idea of color. Ask for two free pairs, one from Freshlook and one from Acuvue, and see which looks better.

As for prices, FreshLook Colors Acuvue 2 and costs about the same for a 6-lens. However, all Freshlook Monthly Disposable Lenses, and Acuvue 2 Colors is a 2-week disposable contact lenses. So it turns out that Freshlook is twice cheaper.

Types of lenses used by Ray-Ban

Ray-Ban uses four different types of lenses for sunglasses. The lens that B15 XLT) G15 XLT lenses, polarized lenses and normal lenses, which do not discuss here because it's nothing special about them (but only in different colors.

B15 XLT Lens

Ray-Ban B15 XLT lenses are brown, blocking 100% of UV rays and allow only 15% of visible light to pass through them (which is a discount of 85% is!). Brown lenses offer a bit 'moreContrast by reducing the amount of blue light, like a lens G15 (which is described in next section). The blue light is easily seen through the eyes and has the effect of softening the other colors that are harder to make our vision. In other words, reducing the amount of blue light, the differences between the colors and brightness of objects more pronounced.

G15 XLT Lens

G15 XLT lenses have the same quality as the B15 XLT lenses, butThey are gray / greenish color. The G15 lens is to develop the original lens, the military pilot who asked Ray-Ban. The challenge was to provide a lens that "it was a neutral color, in other words, a lens that filters the light, such as drawing the human eye. If you have a lens that gives you a little 'less than the contrast between colors, then the G15 XLT lens is for you, because it provides a similar sensitivity to color the human eye. With an aim lower, however, the difference in color and brightnessItems will be dampened. This means that the colors viewed through these lenses are natural and soft on the eyes.

Both B15 and G15 XLT lenses are made of impact-resistant optical glass, which is resistant to scratches course. Quality and stability are important and, over time it will fade in virtually any color.

Polarized Lens

Polarized lenses reduce significantly the amount of glare produced by reflective surfaces such as water orother objects semi-transparent, and even some metal surfaces. Glare refers to the difficulty of light.

Sunlight, for example, the surfaces bounces in all directions (), which is vertical, horizontal or diagonal. For those who are active on a "horizontal" means that means that the sunlight bounced horizontally across the eyes in a similar way. This causes constriction of the pupils and reduce the contrast significantly. Therefore, drivers have difficulty seeing theWay to go, when they go under very sunny (the sun) before them.

Polarized lenses have a laminated surface with vertical strips of a filter, which can actually cut horizontally and vertically polarized light, only the polarized light in. In other words, create, if you happen on a clear lake, you'll probably see the surface or driving a car, you can now progress towards the future.

Some limitations for the lenses that are polarized LCD --Display may be distorted, or you can create a notice of "rainbow" effect when you take the car, the windows are tinted.

All 3 items are very useful, particularly the polarization, but expect to pay a premium for sunglasses.

Lens Base

The base lens refers only to the base curve or the curve in front of the lens "diopter" is measured, which is a term that counts only for the optician. You will discover that many of the Ray-Ban aviator have a "base of the lens 6", which essentially means thatare sufficiently curved and designed to function as sunglasses (that is, covering his eyes enough).

Wire diameter

Lens Size is measured in millimeters and refers to the length (or width) of a lens. Keep your eyes when they make a purchase. Many of Ray-Ban models are available in various dimensions of the lens. Make sure you get the size that fits your face, or you can do at the end with a pair of shades that fit air properly.

Some of Ray-Ban Sunglasses have lens sizethat extra small, small, etc. This is for models that do not resemble traditional glasses with two lenses are called common. These sunglasses have a UNI "lens" design, in which the lenses are perfectly connected with the bridge. For this reason, the traditional dimensions apply. These nuances are looking for a way up.

The Skinny on Putting in contact lenses

Many eyeglass wearers are reluctant to the idea of something in their eyes and think that they could never learn to ask how to get in contact lenses. Which is a shame, because today's contact lenses are nothing like the lens of a decade ago. They are thinner and thus more oxygen in the eye and are therefore much more convenient. It 'also very easy to learn to put contact lenses in.

Like almost everything that can be done, sometimes a little 'practice beforebe completed on them. Some skills require more practice than others. She did not move in traffic in highway run 70 miles an hour, zigzagging between the orbits of the first time I've ever been at the wheel of a car. At least we hope everyone will do that for the first time so drivers. If you're like most people, you were a bit 'worried, though probably take one of the few cars on the road and only through peaceful neighborhoods. But do not even think of todayAbout driving. You just do it. Has a natural ability.

Same thing with the setting in contact lenses. Can be a bit 'scared at first. And the idea of a piece of plastic on your eye may seem excessive, but give him a chance. Probably you will be pleasantly surprised. Most people adapt well to the best list contact lenses today and I wonder why they waited so long after they have experienced significant improvements in their eyes.

Now, with the promotion of 30 dayscontact lens extended wear, you can live and sleep in them 24 hours a day. They are so comfortable and safe for your eyes, which become a real alternative to LASIK. And the best part of 30 days of extended use of contact lenses is that you only have to share contact information or to make a once a month. For those of you who do not like the idea of reducing, contact lenses, so that the task formidable. Put your contacts and then not even think about itfor the rest of the month. And get the advantage of being able to enjoy a perfect 20/20 vision any time of day or night. Imagine waking up in the middle of the night and to be able to now is on your bedside clock without glasses to see set up.

Putting in contact lenses is a bit 'of practice, must be completed on them, but not an impossible task. Your physician will guide you through all the steps. And someoneAmbulance to spend time with you and you have to practice in your contact lenses and each other. They are in every step each time you need to go, to feel comfortable with the process. Do not lean the whole idea of contact lenses until you've tried. You may ask why you waited so long.

Nikon 35mm f/1.8G AF-S DX Lens for Nikon Digital SLR Cameras

Nikon 35mm f/1.8G AF-S DX Lens for Nikon Digital SLR Cameras Review

I was going back and forth with the Nikon 50mm f1.8 lens. I ended up with this one, mainly because I have a D5000 that doesn't have the autofocus motor. I was not disappointed with my choice. Since I've gotten the lens, I've rarely taken it off of the camera. There have been some times where the 50mm wouldn't have worked for the shot I was composing.

The image quality is surprising for a lens this inexpensive. The autofocus motor is nice and quiet, and fast.

Anyone looking for a good, inexpensive prime lens for their D40/60/3000/5000, this is for sure the way to go.

Reflex - What Is A Single Lens Reflex?

The hottest thing in the digital camera market is undoubtedly the digital SLR camera that is better known as a DSLR. While SLR cameras flying shelves dealer, many new users are confused about the terminology. Many people know that SLR stands for single lens reflex. " Since almost all SLR cameras accept interchangeable lenses, it seems, should be known as more SLR (MLR) cameras.

If you understand how the SLR will keep its name, you must immerse yourself in historythe camera. Cameras first were similar to those used today view cameras. The photographer seen through the lens, focusing together and then added to make a single film plate behind the lens of an image. The whole process was crude by modern standards, enjoyed the photographer great control as he looked directly at the lens image effects, compose the shot.

Lifes Although this was good forever, portraits and landscapes, and this process does not lend itself to actionsPhotography. These early cameras could only record one picture at a time. Why do not you ever seen an engine from the cameras.

Recognized the need to predict the effects of risks, begin to experiment with different manufacturers roll camera-film design. With a film in the camera, photographers have been able to shoot lots of photos without recharging. Although this volume is much improved, causes another problem. The roll of film was just behind the cameraOptics, which means that the photographer could not see through the camera to compose and focus.

Cameras Vista seems to keep things in focus

The final consumer was lower rolling cameras typically use low-cost fixed-focus "lens, so that a simple viewfinder enough. Improving the quality of the optics do not seem, however, require the target to be focused, and as a photographer through the lens with a roll-film, this was a big problem. One offirst solutions to this problem was the range finder - a type of camera that offers a distance measuring scale in the viewfinder. By determining the area of the viewfinder, the photographer can match to your attention - usually with very good results.

Twin lens reflex cameras offer a different solution

While the rangefinder type cameras worked well, the camera industry is constantly evolving. A second method allows the photographer to focus and compose appearedThe "twin-lens reflex camera. This camera uses two identical lenses, arranged on the other in the manner of over-and-under shotgun. The film winds through the lower lens, while the photographer can focus through the lens higher. The twin objectives cameras were quite bulky, so that designers have a mirror and glasses, the top of the camera, hence the term "reflex.

Now the user can access the camera at the level of life and continue to see the frosted glass, the image previewMirror behind the lens higher. Because the user adjust the focus lens on top, a transmission moves to the bottom "in accordance with the objective of".

While both rangefinder and twin lens reflex cameras, it offers a credible way to focus and to preview a shot, then neither the photographer who actually look through the lens. The precise composition sometimes difficult.

SLR cameras take a further step forward

In their search, so users do not see the actual "taking" lens,Manufacturer of the camera turned to the periscope - a simple device with two mirrors placed at opposite corners of the light curve. Periscopes are easy to understand - every child can be constructed from some mirrors and some pieces of wood.

In a camera, the lower mirror placed directly in a 45 degree angle behind the goal. Light striking the mirror up to exhibit a glass floor. While a second would mirror the image on the screen to show the user does not seem right,because the mirrors are inclined to reverse things. So designers camera has fixed a system of prisms, according to the image upside down. If you peer through the viewfinder on an SLR, look through a prism, the image on a screen, the image projected by the mirror behind the display lens.

There is only one problem. If you have been attentive, that no doubt have realized that the lower levels of light in the path of the film (or digital sensor, such asbe.) Now, the photographer can see if the lens, but the image can be projected onto the film plane.

Thus, the designers of the camera had to add another wrinkle. They had to move the mirror. Just enough time to do a show, as if the mirror is moved, the photographer did not see what the lens. So conceived return "snapshot" of the mirror. At the time of exposure, the mirror is flying upward, fire shutter and the mirror snaps back. It 'an incredible achievement,If you need to look again at this time flip-top mirror and back in the blink of an eye, again and again for the life of the camera.

Once the immediate return of the mirror has been perfected, photographers can also draw their images from the lens. In contrast to the Twin Lens Reflex, needed this new generation of camera, but a lens to focus and shoot. Thus they became known as ... You guessed it .... Single Lens Reflex.
