Spring has sprung. The weather is getting nicer. Time for a new pair of sunglasses?  It was time for me. Even though sunglasses are not a regular topic of our lighting blog, I felt that my recent experience picking out new sunglasses warranted this post. I was disappointed at the number of myths about sunglasses that were told to me by multiple, yes, multiple, supposedly knowledgeable sales people. So, I figured that it might prove useful to others if I shared my experience and busted these myths with this sunglasses buying guide. 

Myth #1: UV Protection In Sunglasses Not Important

Fact: The sun’s ultraviolet (UV) rays can do several very bad things to your eyes and the area around your eyes: harm the lens, retina, and whites of your eyes, cause corneal sunburn and blisters, increase your chances of getting cataracts, have been linked to macular degeneration (vision loss due to damage due to a small spot near the center of the retina called the macula), cause skin cancer around your eyes including your eyelids, and help cause unwanted wrinkles and skin thickening around your eyes. WOW!  There’s a lot more but it would take more than this short response to get even more technical.

Myth #2: Sunglasses With Glass Lenses Remove All UV Radiation

I visited a small boutique optometry store and spoke to someone with 40 years of experience. He told me that if a pair of sunglasses has glass lenses, then they remove all UV radiation. Not true.

Fact: Glass of almost any kind (building windows, car windows, a pair of clear glasses) can remove some but not all of the UV radiation that reaches your eye. Ultraviolet (UV) radiation is made up of three segments: UVA, UVB, and UVC. Fortunately for all of us UVC radiation is blocked by the earth’s atmosphere, ordinary glass blocks out UVB radiation (the main sunburn ray that causes skin cancer and sun damage) but allows UVA to pass right through (UVA rays penetrate the skin more deeply and can also cause skin cancer, wrinkles, and premature skin aging). However, it is possible to add a special UV-blocking film to ordinary glass or use specially formulated glass (or plastic) to block out 99.9% of UVB and UVA radiation.

Myth #3: Polarized Lenses Also Mean UV Protection

Two representatives in the optical department of a national chain of retail stores told me that if a pair of sunglasses has polarized lenses, then they also provide UV protection. Not true.

Fact: These two features of sunglasses are entirely different from one another; one feature does not imply the presence of the other feature. Polarized lenses minimize direct and indirect glare from the sun; they allow you to see more clearly when the sun’s rays are reflected off flat, smooth surfaces like water, road pavement, and car hoods. Polarized lenses are not designed to reduce the ultraviolet radiation that reaches your eye.

Myth #4: More Expensive Sunglasses Have The Best UV protection

Fact: This is not always true. Relatively inexpensive sunglasses can sometimes block 99%-100% of UV radiation but they are not easy to find. However, you should be careful about still another problem – inexpensive sunglasses sometimes are non-uniform in thickness and have poor optical quality. This can mean that they sometimes distort the shape or clarity of an object, depending on what portion of the lenses that you look through.

Myth #5: Sunglass Tint Is Not Important

Many people think that the tint of the sunglass lenses is not that important. That it is purely an aesthetic decision based on your personal preferences and the “cool factor” you’re looking for.

Fact: The tint or hue of the sunglass lenses plays an important role in the perception of colors. Yellow or rose tinted lenses generally can make it difficult to distinguish different colored traffic lights. Gray, green, and brown lenses, however, minimize color distortion and are a better choice when you’re driving a vehicle. Some specialized sunglasses can have a special tint that are designed to enhance your performance of a specific task or sport; e.g., at least one sunglasses manufacturer has created a whole array of lens hues, one of which can possibly improve your tennis game by enhancing the color of the tennis ball.

Myth #6: Size Of Sunglasses Not Important

Most people choose the size of their sunglasses on whether or not they think they look “cool.” Thus, they think that size is not important.

Fact: Size, at least when it comes to sunglasses, does matter. It’s this simple: The larger the sunglasses, the broader the protection of your eyes, eyelids, and the skin around your eyes against UV damage. However, you can have all of that and still look “cool.”

Enjoy your spring and summer and enjoy your new sunglasses.

Looking to hire the best electrician you possibly can in MD, DC or VA? We don’t blame you. As the economy faces serious challenges and uncertainties, families are forced to live on a stricter budget. Companies throughout the DC Metropolitan area must also operate on a much tighter budget than years past. It only makes sense for you to wonder exactly how to hire an electrician. You want to hire a reliable, quality electrician who can answer your questions and solve any electrical problems you may be having. Here at Kolb Electric, we thought it would be helpful to create a guide for selecting the best electrician.

There are so many electricians in the MD, DC and VA market that it can be difficult selecting one!. To make a list of prospective contractors, get recommendations from your family and friends. If you cannot get any, search online to compile a list of local electrical contractors. This is an important first step in finding the best electrician to meet your needs.

After you’ve prepared a short list of prospective electrical contractors, you may still be wondering how to hire an electrician. One thing you can do is to check the licensing credentials of these electrical contractors. The best electricians are trained, skilled and experienced. You can use the Internet to determine whether a prospective electrical contractor is licensed or not, and you can also check whether the license is still valid or not. An electrician without a license or with an invalid license should raise big red flags!

You should also use the Internet to read reviews posted by others who have some experience working with the prospective electricians you have on your list. This is an excellent way to determine the best electrician for you. However, you should approach these results with a grain of salt. Someone with a bad experience is more likely to post something negative online than someone who has had a great experience. Always put more stock in what you’ve heard from family and friends.

When you reach the point where you have a list of just a few quality prospective electrical contractors, the next step is to contact them so you can secure and compare quotes. Keep track of exactly what services the contractors claim they will provide when compiling quotes. Since your list now features only quality contractors, cost is the next factor you should focus on.

Finally, in order to really know you’re hiring the best electrician you can, ask a lot of questions to prospective contractors. The quality of their answers can go a long way in helping you hire the best electrician. Ask contractors what experience they have dealing specifically with the electrical problem you have.

We hope this helps you better understand how to hire an electrician. There are several steps involved, but they are all essential to helping you select the best electrician you possibly can!

ElectricMan is committed to helping you make the most out of your electrical system, appliances and usage, which is why your top Frisco electrician is giving homeowners some tips on how to take good care of your electrical systems and how to get the most out of your home.

 #1 Turn off the lights and lower your bill.

Electric bills these days can give you headaches in and of themselves. However, there are a few things you can do to lower your bills and still enjoy your electricity. Turning off the lights when you’re not in a room; consider installing a motion sensor switch for the outdoor lights you may forget to turn off.  Unplugging an appliance that you’re not using, or even installing alternative power sources like wind turbines and solar panels can significantly reduce your power consumption without infringing on your everyday usage. You can also use indoor generators to power your home without needing to be connected to the power grid.

#2 Keep up with electrical maintenance in your home.

Doing regular electrical maintenance in your home every two years can mean the difference between a happy, powered home and a mess of molten wire and old circuit breakers that don’t work. Hire your local electrician to come take a look at the entire electrical system in your home, and act upon his recommendations as soon as possible to give your home’s electrical wiring a long life.

#3 Take care of your smoke detectors and your smoke detectors will take care of you.

Smoke detectors are an invaluable and potentially life-saving part of any home. Keeping them in good working order and supplied with fresh batteries might just save your life. Be sure to swap the batteries of your smoke detectors every year (coinciding with the time changes is a good way to remember), and change out detectors every five to seven years.

#4 Protect your home with the right equipment.

Another important aspect of being safe and secure in your home to ensure your home is properly equipped with surge protectors, AFCI breakers and GFCI outlets wherever they are needed. These pieces of equipment not only can protect and preserve valuable appliances or expensive wiring, but they can keep you out of harm’s way in case of an electrical emergency in your home.

#5 Hire a professional for electrical remodeling jobs.

Whether you love hanging lamps or dimmer lights, homeowners who are fond of ambient lighting and are in need of some remodeling should always remember to call their top Frisco electrician to carry out the lighting installation. Installing lighting is a very intricate process that can get difficult and dangerous if you don’t know what you’re doing.
