Sunglasses

In general, children are more vulnerable to eye injuries compared to adults, partially because they spend more time playing outdoors. Another reason is probably that children’s eyes are immature and more fragile. For instance, ultraviolet (UV) rays and excessive sunlight bouncing off water and sand can lead to a painful sunburn of the eyes in both children and adults. Kids are more likely to receive excessive UV exposure because they stay more frequently in outdoor environments. Wearing sunglasses during outdoor sports is important, especially for children. Children who like sports such as basketball or football still need to protect the eyes by choosing protective sunglasses.

What styles do children like?

There are various sunglasses for children to choose from. Children can get all kinds of sunglass shapes, such as oval, round, rectangular, and geometric shapes which are very popular. These shapes also have cool colors such as black and red. Children who wear plastic frames look like miniatures of the adult style. A trend is that children want to wear sunglasses just as their parents or the elder siblings do and many sunglass companies have seen this opportunity and provided great products. You can buy children’s sunglasses from optical chain stores like Pearle Vision, local optician shops, and sunglass specialty stores like Sunglass Hut. Some large stores usually display children’s glasses and sunglasses in exclusive areas.

Children nowadays are more and more fashionable. They prefer styles that mimic that of adult sunglasses. Some sunglass designs that are inspired by recognizable cartoon or television programs are very popular among children. This icon effect has been applied by many eyewear brands and manufacturers. Harry Potter glasses are just a successful example. Clip-on sunglasses that are reasonably priced can also be a good choice for children. Since there are so many sunglasses styles for children, you should choose an appropriate frame for your kids under the consideration of their health and safety.

Protection for children’s eyes

Although regular sunglass lenses are not shatterproof, parents can choose polycarbonate lenses for their kids for impact-resistance. Sunwear lenses made of polycarbonate are the most popular for children. Due to their extreme impact resistance, polycarbonate lenses help protect the eyes of children who participate in sports frequently. Eye care professionals call these products specialty eyewear or sports eyewear. Of course, these sunglasses should first ensure UV protection. In fact, most sunglasses including those for sports use can offer 99 percent or 100 percent protection against harmful ultraviolet rays.

Other Sunwear accessories

Typically, there are some accessories when you choose sunglasses. You can get detailed information about sunglasses from an optician who will teach you how to care for your sunglasses with their products including cleaning cloths, and sunglass cords (also called retainers). In addition, opticians may give some suggestions on the way to place sunglasses.

I have a friend who likes to collect all types of eyeglasses designed for different people. I don’t know why she has such a different habit but I must say some of the glasses she buys from other countries are very beautiful. I am also an eyeglasses wearer but I don’t have time to make a careful selection. More than often, I enter an entity store in the downtown area and take the shop assistant’s advice. I pursue efficiency and I trust their professional suggestions based on their experience and knowledge.  I seldom study the different functions of prescription glasses and I don’t care much about the appearance of glasses either. I just regard it as a medical device to protect my eyes and make me lead a normal life. Since the basic function is to make wearers see objectives more clearly, I don’t think the fashionable outlook matters a lot. But my friend thinks it is a symbol of personal taste and we should learn to make a good match. In addition, different glasses have their unique function, which calls for consumers’ carefulness to make a wise decision. So my friend often searches the Internet to see whether there are some new styles of glasses.

She has a fixed online shopping place and she recommends it to all the people she knows because she believes it is a good resource to share with others. She has been an online shopper for so many years but she really began to buy eyeglasses from online stores not a long time ago. Even so, she has a sharp sense when making a choice and she knows which type of glasses suits what kind of person. So when we need to buy glasses, we naturally turn to her for help. She is very generous to tell us some useful tips and even directly helps us to make a choice and fill in the order. What a great friend!

She often notices the news on the page site of www.cheapprescriptionglasses.net to catch up with the times. She chats with the service personnel through the live support and plays the virtual fitting room to see the effects of different types of prescription glasses on different people. Another reason to explain her preference for that store is because of the reasonable price of glasses. She speaks highly of the good quality as well as the satisfactory prices.

Choose only quality Sunwear

Some people wonder whether using inferior sunglasses with poor UV protection is more damaging than wearing no sunglasses at all. Although there are no confirming cases, it is to some extent reasonable to say that low-quality sunglasses are more harmful. Customers should always select quality sunglasses for best comfort and vision as well as eye protection. Besides sunglasses, large hats are also helpful in offering sunlight protection outdoors.

Different materials offer varying degrees of UV protection

Sunglasses with CR-39R plastic can absorb about 88% of UV light and this number for polycarbonate lenses is 100%. However, sunglass lenses made of triacetate only absorb approximately 40% of UV rays. Lenses made from other acrylic materials have varying UV absorption abilities. Sunwear buyers are highly encouraged to check the degree of UV protection with the seller. For children and people who need protective eyewear, polycarbonate lenses are a perfect choice, because their 100% UV protection is inherent. To gain 100% UV protection, it is quite necessary to get sunglasses from trustworthy sources such as reputable companies, specialty sunglass stores, or optical professionals.

Optional lens colors

UV absorption capability deserves the top priority during sunglasses selection. But lens color is also an important factor for some customers. Some colors such as neutral density gray will darken the surrounding environment but will not affect the wearer’s color perception. Some lens colors may change color perception. Remember that lens color does not only determine lens darkness. For example, orange lenses are lighter than brown lenses. Most lens tints are still closely related to optical features or properties. Some lens tints can help heighten contrast in certain conditions, while some others preserve normal light perception.

Polarized Sunwear lenses

Polarized sunglass lenses block horizontal light and allow vertical rays, which is helpful during outdoor activities such as fishing, diving, and so on. This type of lenses reduces glare by blocking light reflection from smooth surfaces. The principle is that polarized lenses are able to filter out those horizontally reflected rays, which are the major source of glare perceived by people. Unlike anti-reflective coatings that can be applied to lenses for both outdoor and indoor uses, polarization is always added only to sunglass lenses for use outdoors.

Traditional sunglasses have very wide applications covering even all groups of people. UV protection provided by sunglasses has benefited millions of folks around the world. Taking a simple example, sunshine may make drivers uncomfortable during driving, so that most motorists resort to sunglasses for help. Sunwear with tinted lenses will effectively help filter out excessive sunlight as well as harmful rays included. These conventional sunglasses perform quite well in people with 20/20 eyesight. But for drivers with a refractive vision problem, non-prescription sunglasses are ineffective in providing clear vision. In this case, prescription sunglasses can a convenient and satisfying solution.

Serve as an alternative to a combo of Rx contacts plus clip-on

Some people like to participate in outdoor activities wearing contact lenses. Prescription contact lenses do offer necessary vision aid while eliminating the concern about breakage. But a common complaint is that contact lenses are quite annoying used in an outdoor environment because they have to battle with sand, sun, wind or water. It is widely known that the microorganism may cause potentially serious eye diseases. Currently, prescription sunglasses are a good option for these kinds of conditions. Wearing sunglasses removes nearly all potential risks of developing eye infection or even disease. In addition, prescription sunglasses can also be a good successor to clip-on sunglasses, which traditionally stay over regular prescription eyeglasses.

Single-vision and multifocal types

Prescription sunglasses are right for people who have vision problems such as presbyopia, myopia, or astigmatism. There are several types of prescription sunglasses available using different lenses. Each of these refractive conditions leads to a type of single-vision prescription sunglasses. Within this category, prescription sunglasses will function as competent as myopia glasses and hyperopia glasses. Differently, presbyopic patients can choose bifocal or progressive lenses to help them read a book or magazine. In this case, prescription sunglasses are similar to multifocal glasses in terms of visual aid. Except for prescription sunglasses that offer various vision correction, there are still someones providing eye protection. For instance, prescription swimming goggles are a good choice in a swimming pool.

Wraparound lenses limit vision correction

Prescription sunglasses are available in styles as many as non-prescription sunglasses. But there are limited prescription sunglasses in a wraparound style that curves around the head. Generally, prescription sunglasses with extreme curves may affect vision, so that some manufacturers provide prescription sunglasses in a limited curves range. Most people know that lens curves are closely associated with lens powers. The consequence is that wraparound sunglass lenses can deal with limited degrees of refractive errors. More specifically, severe myopia and hyperopia can not be addressed by wraparound lenses. In most cases, wraparound lenses can only help correct vision errors that are below +/- 5.00. Customers should consult an optician or eye doctor before buying such prescription sunglasses.

Possible lens materials

Prescription sunglasses exert no unusual requirement on the lens material. A variety of lenses is available in the sunglasses market, including high-index, polycarbonate, regular plastic, Trivex, and even glass materials. Lenses with a photochromic tint can change their color automatically according to the intensity of light. But this type of lenses may not change the tint inside a car as the windshield has blocked the UV rays out.

UV protection can equally be guaranteed

Customers who use prescription sunglasses sometimes show concern about whether they can get enough UV protection. UV protection is not directly associated with the color and density of the tint in lenses. As a result, customers can choose any lens which has been verified to have 100 percent UV protection. In addition, prescription sunglasses can also block glare with the use of polarized lenses. Some optical shops may provide discounts on prescription sunglasses.

Clip on sunglasses is quite special in that they are placed over prescription eyeglasses in order to block the glare of the sunlight. Using sunglass clip-on, it is unnecessary to remove the eyeglasses. In fact, these clip-on sunglasses come with no temples and attach to the frame of prescription glasses. Nowadays, this style of sunglasses is very popular among outdoor activity and sports enthusiasts. They usually need vision correction and UV protection at the same time. Currently, there are mainly three types of clip-on sunglasses, namely standard clip-on, flip-up clip-on, and magnetic variants.

Standard clip-on

The standard form clip-on sunglasses have a clip at the center of the bridge and fasten onto prescription glasses over the same spot. In other words, such a clip-on has a claw that hooks to the regular prescription frame. It is worth reminding that these clip-on are completely separate from regular glasses. It is necessary to put them on when UV protection is needed. And once the vision correction is necessary, they should be taken off. Many people think this is cumbersome. In typical, there are lenses with UV protection, coating, and tints. Prescription eyeglasses come in different frame shapes such as square, oval, and circle so that clip-on sunshades thus have corresponding shapes.

Flip-up clip on

The second form is a flip-up clip-on. In typical, these clips use a magnet to attach to a prescription frame, so that they are sometimes called magnetic flip-ups. They usually require a bit of effort to snap them on. Different from the standard clip-on, flip-ups do not require frequent insertion and removal. These clip on can be simply flipped up and then will provide unobstructed views when they are not in use. Based on personal tastes, this kind of clip-on sunglasses comes in different shades. Similar to standard ones, flip-up clips have UV protected and coated lenses.

Magnetic clip-on

The third type is magnetic clip-on sunglasses. This form has invisible magnetic clips that can fasten along the sides of prescription eyeglasses. With the magnetic feature, these clip-on are easy to use and they just "click" into the right place. Also due to its magnetic feature, this type of clip-on is often made of a titanium frame. Other aspects such as shapes and shades are similar to the standard type and flip-up type.

Tips for selection

With the wide availability of three forms of clip-on sunglasses, it is also important to know something about how to choose an appropriate one. A must-know point is that magnets may interfere with pacemakers. Users involving related tasks should make an intended consultation before buying a magnetic clip-on. In addition, the shape of a clip-on should exactly coincide with the shape of prescription glasses. Compared with prescription sunglasses, clip-on is much more affordable for ordinary people.

Most people resort to sunglasses for UV protection. This is the commonest practice. But for people who need visual aid from prescription eyeglasses, using regular sunglasses outdoors may cause a conflict. Clip-on sunglasses and prescription sunglasses have been innovatively created to eliminate this concern. While these two solutions are gaining recognition, fewer people know another option that is generally more effective and advanced. They are called photochromic lenses and Transitions Optical is the most famous manufacturer.

Transitions lenses and sunglasses benefit of Transitions lenses

In detail, Transitions lenses can change their colors according to surrounding light conditions. The company claims that Transitions lenses can darken in bright conditions so as to provide enough UV protection as well as sunglasses do. This advocated feature of Transitions lenses actually attracts a large group of customers, because they think that a separate pair of sunglasses is bothersome. In the remaining part, this article instead states some drawbacks of Transitions lenses, with an expectation enable customers interested in these lenses to get a comprehensive evaluation.

HEV protection is beyond Transitions lenses

Transitions lenses can provide UV 400 protection, which is sufficient in most states of the USA. But these lenses can not replace sunglasses in some aspects. For example, Transitions lenses do not fight against high energy visible (HEV) light. Situated in the violet band from 380 to 530 nm in the visible spectrum, high energy visible light is high-frequent and commonly referred to as the near UV range. There is a high occurrence of HEV light from pools, sidewalks, and sand.

HEV protection from sunglasses is important for ordinary people, especially for younger children because their eye lenses are thought to transmit more HEV light than adults. Without proper protection, HEV light may lead to age-related macular degeneration, which has been proved by quite a few studies. Only special HEV sunglasses can filter out the near UV range. Currently, only polarized sunglasses can offer protection against HEV light.

Transitions lenses are ineffective behind a windshield

In addition, Transitions lenses will not darken when the wearer is in a vehicle with a UV protected windshield. The exact reason is that Transitions lenses will only make respond to the changes in the number of UV rays in the current environment. When UV radiation is blocked by a windshield, Transitions lenses on the wearer’s face inside the car will not be triggered. In this case, Transitions lenses are too clear to provide continual protection against glare and eyestrain. These lenses just maintain a clear status as they do in an indoor environment. Due to this shortcoming, Transitions lenses behind a vehicle windshield are actually less helpful than regular sunglasses.

Transitions lenses offer a small coverage

Always coupled with small frames that only cover the immediate eye area and little of the surrounding area, Transitions lenses only offer normal eye protection against UV light. Most sunglasses provide larger coverage that can protect the fragile skin and still block sunlight from more angles. In this way, regular sunglasses offer extended protection against harmful rays.

Transitions lenses are not for everyone

In conclusion, Transitions lenses are a good choice for people who need to regularly move from indoors to outdoors or vice versa. This group of people will gain great convenience from these glasses. They no longer need to make switches between prescription glasses and UV sunglasses from time to time. But for those spending an extended amount of time outdoors, sunglasses are irreplaceable.
