Prescription sunglasses represent a combination of regular glasses with a dark lens design. Prescription sunglasses use different types of lenses, and here we can count polarized lenses, anti-reflective lenses, blue blockers, photochromic lenses and gradient lenses. It is important to mention here, before going on with the description of prescription sunglasses, that you can only order this kind of eyewear based on an ophthalmologist’s recommendation and after careful medical examination. Some health condition such as eye surgery may require total prevention of sun exposure. This is why most often doctors prescribe sunglasses with  99 or 100% protection against UVA and UVB.

Some prescription sunglasses rely on a wraparound design that prevents the UV rays from entering from the sides. The frame makes such protection possible, because a too thin or small frame design will be insufficient. As for the anti-reflective properties, all quality sunglasses should incorporated the polarized coating for a superior protection of the eyes. Mirror-coated lenses are sometimes used for the same purpose of reducing glare. The stage of the eye condition will also have an influence on the design of the prescription sunglasses.

It is sometimes difficult to create functional prescription sunglasses for advanced forms of myopia where the thickness of the lenses is very high. The presence of two or more health problems at the same time could also become an obstacle for the design of prescription sunglasses. The doctor should be able to recommend an adequate course of action, with the mention that the design of highly specialized prescription sunglasses is more difficult. Moreover, price awareness is another important element given the fact that prescription sunglasses will always be more expensive, as the number of specialists who can design them is smaller too.

Glass is a good lens material because of durability and visual acuity, but it is considered too heavy by many users. The most popular lens choice is polycarbonate that makes the fishing sunglasses lightweight and resistant to impact, although rather prone to scratch if compared to glass resistance. A good word of advice here is to avoid fishing sunglasses with acrylic lenses because they can cause viewing distortions despite their anti-glare properties. Another element that should influence your choice of fishing sunglasses is lens color; gray, copper, brown and amber are the most frequent of all.

There is no color distortion with gray lenses, and the light absorption rate is high. These fishing sunglasses go great for open water fishing on bright sunny days. Copper fishing sunglasses have a soothing impact on the eyes, and if you need higher sighting abilities, then, this is the perfect lens color for fishing sunglasses. Brown works great for all circumstances too because of the great contrast and the real color perception. You can use brown fishing sunglasses on more or less bright days in streams or on lakes alike, and you will be satisfied with the quality they provide.

When it is forecast or when you go fishing at dawn or at dusk, the best fishing sunglasses are those with amber lenses. Then, besides the lens color, you should also be careful with the anti-glare properties because the polarized coating is the only protection against reflected light. Plus, without polarized lenses, flat or bonefish will be impossible to catch. Last but not least, good sunglasses will also prevent wind and insects from entering your eyes, increasing the comfort and making fishing even more enjoyable.

Shattering and chipping result from the contact of poor quality motorcycle sunglasses with small pebbles for instance. Glass lenses are a no-no for bike riding because of the risk to break and injure the biker. The best lenses for motorcycle sunglasses are made of polycarbonate that is resistant and very lightweight matching extreme travel conditions. All the companies that design eyewear for motorcycle use have special testing procedures to check the resistance of motorcycle sunglasses to impact and temperature variations.

Moreover, motorcycle sunglasses include special anti-glare coating that is a form of polarization for the elimination of the contact between eye and reflected light. The vibration of light waves is an element that poses no kind of problem with other types of eyewear, but in the case of motorcycle sunglasses the shock has to be absorbed by the polarized coating. The relevance of such features is very high given the fact that it is unacceptable to ride the bike when the road is too bright or you have to squint against the sun. From this point of view motorcycle sunglasses are important for road safety and health protection if we consider the impact of reflected light on vision.

Last but not least, motorcycle sunglasses need maximum ultraviolet protection for the entire light spectrum. This means that there should be a balanced combination of UV protection and polarization. You don’t really need anti-glare features on overcast days, but the presence of clouds does not exclude the action of the ultraviolets. Consequently, eye protection require the use of motorcycle sunglasses even on low brightness. Macular degenerations, cataract and lots of other eye disorders are less likely to develop if the eyewear is adequate and of good quality.

Polycarbonate lenses also provide a full protection against all the radiations in the UV spectrum thus eliminating the risk of dry, irritated eyes and blurred vision. Furthermore, military sunglasses require well designed frames too, as they have to be able to absorb shocks and show durability for harsh usage conditions. Field operations, the impossibility to care for the eyewear constantly and the action of the elements can put a lot of stress on military sunglasses, and unless they are well designed they will not last for extended wear. Here are some more elements that make military sunglasses stand apart.

First of all, military sunglasses include all sorts of elements meant to insure a good comfort level. All sunglasses are designed to be comfortable, and match physiognomy but military sunglasses have supplementary temple tips and nose pieces for extended wearing. Moreover, in special movement conditions, the wraparound shape ensures that the sunglasses remain in place. Some military sunglasses also have straps that allow good anatomical adjustment for eye protection and physiognomy match. Lots of consumer categories presently rely on military sunglasses for casual wear, and they certainly see the difference in quality.

The resistance of the items and the superiority of protection make such items eligible for almost anyone. Nevertheless, you could be tricked into buying very inspired imitations or copies of real military sunglasses, and the protection provided by such fakes will certainly be inferior. You need to check all the details about such products, and be suspicious if they are cheap. The type of filters incorporated and the reputation of the producers could also be conclusive. Make good choices, but don’t waste your money on military sunglasses to wear as headbands.

Damage to the frames could also impair the efficiency of your sunglasses, because the eyewear will no longer fit on your face. Sunglasses cases therefore make the best way to protect the sunglasses, which is why lots of retailers or manufacturers provide matching items: case and sunglasses. Usually, the more expensive the eyewear, the better the sunglasses cases. Thus, for a cheap pair of glasses you are more likely to get a cloth case. The protection range will be lower possibly against minor scratches. Plastic sunglasses cases are more efficient and available in different shapes, sizes or designs.

Plastic sunglasses cases are also considered better than metal ones because of their flexibility and bounce back feature in case of an impact. On the other hand the main inconvenience of metal is that cases could remain dented after impact. Do not go for very expensive sunglasses cases unless you are sure that this is what you want. Exclusive eyewear usually requires more special protection, because perceive the eyewear as something valuable that has cost you a lot of money. In fact the main thing you should be concerned about is that the sunglasses case be practical and easy to carry.

Buy hard, metal or plastic sunglasses cases for more protection. Other materials can be fiber glass, vinyl and even leather. Hard sunglasses cases are more difficult to use because they have to be opened on one edge to get the sunglasses out. Pocket cases on the other hand allow one to get the sunglasses out easily without any difficulty, but they don’t provide the same level of protection. Better go for the cases that match with the sunglasses as closely as possible to reduce the damage risk to nearly zero.

Now that Lasik vision correction surgery has been accepted for a number of years, there are several popular options for the procedure.  One of these is IntraLasik, or Intralase, or bladeless Lasik.  As the name implies, there is no cutting of the eye with a blade involved, instead the flap in the eye is made using a laser.  Since bladeless Lasik is a newer procedure, there are a number of opinions around about how well this procedure works. We will inspect each opinions closely as we go along.

First, more Lasik clients get 20/20 vision or better using IntraLasik.  Any Lasik procedure cannot guarantee perfect vision for every client, though more than 90% get results to at least 20/40 vision.  However, it is true that the new techniques of IntraLasik do get even better statistics for giving clients clear vision.

The second common contention is that LASIK surgery can’t be tailored to conform to individual needs.  This is not true. The Lasik physician has control over the use of the laser for each individual in the same way that he can control the microkeratome blade.

IntraLasik can be used for both a standard and a custom Lasik procedure.  This is true.  Custom Lasik procedures using Wavefront technology (another somewhat recent advances in Lasik vision correction) can easily be used with a laser to make the initial flap. In fact, most doctors recommend LASIK to correct eye problems. It is in this moments where you don’t really want to go cheap and you want to be sure you are investing the right amount in finding the proper doctors that you need.

Some have heard that using the laser is less accurate than the standard Lasik procedure. This is not true since lasers can be controlled to micron level accuracy.  This gives the Lasik Eye Surgery physician extreme control to create exactly the flap needed for this particular individual eye: the precise size, shape, and depth for successful completion of the Lasik procedure.

Another contention is that IntraLase is a new procedure that needs to be studied and refined.  On the contrary, many of the most honored Lasik physicians strongly endorse IntraLase due to the good track record from the Lasik procedures.  In addition, the quality of the machines and the precision that they give these Lasik physicians is very impressive.  So the question is: which are the best LASIK Doctors out there? Well, this is not an easy question to answer. But in my personal point of view, and please remember that this is 100% subjective, I will recommend LASIK Massachusetts, mainly because they have the top doctors for this procedure in the country.

Many of the top notch Lasik doctors recommend this as a procedure of choice, assuming cost is not a significant variable in the decision of which Lasik procedure to use. That’s why the only determinant on whether a patient should undergo LASIK or not is the cost. The procedure is relatively pricey. The procedure, however, is very safe and many surgeons around the world recommend LASIK. So if you want the best, you do need to pitch in some amount.

Similar to the contentions above, some people think that Intralase is not a sufficiently tested Lasik procedure option. On the contrary, more than one million of these procedures have been performed, and the impressive track record for this Lasik procedure has been discussed above.  More and more Lasik physicians are trained in this option, and we will see many more such Lasik procedures in the future.

As a last advice, I can only recommend that you take your time choosing the proper doctor, this is a serious procedure and you should only do it with the medical team you feel comfortable with. Best of luck and thanks for reading.

The doctor and I talked about the surgery; he was persuading at the same time realistic. He stated that one of my eyes would be a good candidate for total vision correction, but the other eye would likely see only some (though possibly major) improvement. He stated that about one of his Lasik procedures per month are with clients with the same level of poor vision of my worst eye.  So that made me feel good!  

I would also like to encourage those people with some problems to go ahead and visit their local Lasik center (in my case I went to the Denver Lasik Eye Surgery clinic and I can’t complain!) to talk to the professionals there. As I mentioned earlier, I have had some occasional problems with dry eyes. I also have problems with my pupil; it dilates fast. Both of these can be reasons to be dissuaded from Lasik, but in neither case were my problems significant enough for the doctor to consider me not a good Lasik client. Do go and discuss your individual case.

I cannot say that the information I was given made me totally relaxed about the whole procedure. Before I had the procedure done, I tried to reason with myself not to get it.  I followed all what the Lasik doctors told me to do  after the procedure, and I am so happy with the results! I could see much better even directly after the operation was over, and things have continued to improve. I personally do not have any of the problems that are often mentioned as effects, such as halos around lights, etc. I would strongly encourage anyone to be brave enough to go down to your Lasik center and at least talk about the Lasik procedure with a knowledgeable professional.
