Prescription Sunglasses – Worth The Money?

Thursday, February 18th, 2010

Although very often we tend to consider eyewear as a form of decoration, sunglasses are first and foremost a protection of the delicate eye system from the impact of the ultraviolets. Special vision problems prevent lots of people from being able to wear sunglasses, which makes them even more exposed to various other eye health problems. Hyperopia, myopia and astigmatism are just a few examples here. Prescription sunglasses could be a solution for improving sight and protecting eyes from the action of the UV radiation at the same time. The UVB rays cause sunburn while the UVA rays get absorbed by the human eye lens.

Prescription sunglasses represent a combination of regular glasses with a dark lens design. There are different kinds of lenses used for prescription sunglasses, and here we can count polarized lenses, anti-reflective lenses, blue blockers, photochromic lenses and gradient lenses. Prescription sunglasses are designed only according to the ophthalmologist’s recommendations, and sometimes design is not possible because of the specificity of the eye problems. Total protection against the UVAs and the UVBs should be covered at optimal parameters, due to the fact that people with eye surgery should not be exposed to powerful radiation.

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 glare, 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. One special mention here is that the design of the prescription glasses also depends on the stage of the eye health condition.

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. Very few companies can provide such designs for low prices; the more complex the prescription sunglasses, the higher the price.

Sunglasses for Sports

Thursday, February 18th, 2010

Sports sunglasses are a bit different from the casual eye wear not only by features but by purpose and nature. While fancy sunglasses make a combination of protection and style features, sports sunglasses emphasize their functional size over the trendy one. Usually designed to also match fashion trends, such items impress by the way they serve the user outdoors. There has to be maximum visibility, full blockage of harmful radiation and protection against debris as the main expectations you can formulate in relation with sports sunglasses. Golf, cycling, extreme sports and even hiking require the use of special protective sunglasses to stop the eye contact with the UV rays.

 

The extreme sports features and the casual street style often meet in some sports sunglasses models. You will fully appreciate the anti-glare features and the quality of the polarization when snowboarding, skiing or practicing any outdoor sport. Self-locking screws, face hugging contours and high precision hinges, these are indeed features that you’ll only encounter with certain high quality sports sunglasses. For increased durability and resistance to impact, sports sunglasses normally rely on polycarbonate lenses and nylon frames. The breakage hazard makes glass incompatible with sports activities.

 

Besides the blockage of the ultraviolets, sports sunglasses could also prevent the contact will all sorts of debris or insects that get in the eyes at high speeds. Good sports sunglasses allow the wearer to focus exclusively on the activity without having to squint the eyes or rub them in order to improve visibility and get the dust out. Therefore, when and if you shop for sports sunglasses, it is probably a good idea to get some wraparounds because they protect the eyes on the sides as well thanks to the frame design.

 

It is difficult to make a choice sometimes give the large variety of designs and models available with sports sunglasses. An optician’s shop and not the Internet makes the best place to shop for such items. The problem with the online orders is that you cannot try the sports sunglasses before the purchase and there are fair chances that the items will not fit you. Even when you get the right size, the entire physiognomy could be responsible for the mismatch. Maybe the design is not good for your nose, eyes and face shape, and you need to search a bit more; this is the reason why Internet orders may fail to satisfy your needs.

Golfing Sunglasses

Tuesday, December 29th, 2009

Precision is one of the main demands of golfing and without the right equipment the strikes don’t have the same efficiency. And a golfer’s apparel is not complete without golf sunglasses. Besides personal comfort, such items allow for good club choices and strike efficiency. Without eye protection, you’d be squinting at the sun incapable to see where the ball reaches on the course. No matter the weather, golf sunglasses should be worn constantly: from bright sunshine to overcast days, the action of the ultraviolets will be less harmful.

 

Golf sunglasses have some special features incorporated. Both lenses and frames have to be well chosen in order to provide efficiency. Any golfer depends on a snug fit of the glasses for a good face comfort. Therefore, the frames ought to be flexible and light. Try several pairs on before deciding which is the better fit. Another important issue to consider here is the peripheral vision and the eye protection. Wind and debris could affect visual capacity, therefore, choose some frames that reduce the impact of such factors.

 

Lenses are more important than frames. Maximum protection against the UVA and the UVB: this is what you should find in a good pair of golf sunglasses. Try polarized lenses because they provide protection and reduce the glare. Depending on the weather, professional players will often alternate the golf sunglasses. For instance, a superior visible light transmission makes a difference on very overcast or partly cloudy days, which is a great advantage that some lenses can provide.

 

Special features can also be incorporated in very professional golf sunglasses. Thus, the lens features prevent sweat or dirt from sticking on the lens surface, not to mention that shadows get highlighted too. This considerably improves visibility and maintains it for a longer period of time. Read the instructions of golf sunglasses carefully to learn about any special cleaning tip. Unless you are pro or someone who plays golf very often, you should carefully consider the budget, your needs and the extent at which you will wear the glasses. When playing golf only occasionally, there is no point in buying several pairs of golf sunglasses for alternate wear.

How To Pick Sunglasses

Monday, December 21st, 2009

Poor quality, that is what comes with cheap sunglasses. Low standards are not a problem with reputed brand names because their best sunglasses represent a continuation of tradition and the preservation of good reputation. Lots of harm can be caused to the eye if low quality sunglasses are used. The pupil dilates because of the dark lenses, if there are no anti-UV protective features, then the ultraviolets and the infrareds become very dangerous for the eye. The radiations could impair sight and cause a wide range of ophthalmic dysfunctions such as affections of the crystalline or cataract.

 

Image distortion is one other flaw of poor quality sunglasses. This is often caused by plastic lenses that have faulty dioptric values which have not been established by medical prescription. Face match and comfort make other criteria for appreciating the features of the best sunglasses. Physiognomy plays an important role in the choice of sunglasses, and you will understand the difference between matching and not-matching glasses by trying several pairs on. Then, besides UV protection, the best sunglasses also reduce the glare by the anti-polarizing coating that covers the lenses.

 

Can lens color influence a classification of the best sunglasses? Well, opinions differ here. The capacity to reduce light intensity and absorb the colors of the visible spectrum varies with the color. Not anyone can wear dark lenses for instance because they can reduce visibility: this is the reason why drivers, pilots and many other wearers prefer gray. The best efficiency in terms of radiation absorption features is that of green lenses, but green makes it hard to distinguish between colors. Greeninterferes with the perception of blue, red, orange and violet. For tropical locations, green lenses make the best sunglasses, not to mention the relaxing effect of the color.

 

Warm and cold environments are perfect for both cold and warm environments as well, and radiations are very well absorbed. As for yellow lenses, wear them at sunset, at dawn or on foggy weather, because they are not efficient against intense brightness. Protection and comfort, these is what the best sunglasses should provide. Wraparounds are among the most advanced of items because they protect the sides of the eyes too against the impact of the ultraviolets. And keep in mind that the price should not reflect the special design of the frames or their glamorous look but the properties of the lenses. Eye protection is the most important!
