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.

If you own an RV, you are probably always looking for ways to make life easier. One of the areas you may struggle with is providing consistent electricity to an RV. When you are staying in an RV park, there is often a power source—however, if you want to use your RV’s power system at home (to utilize it as a guest house, for instance) you may feel at loss as to what you need to do. Follow this advice from an electrician in Los Angeles and see what you need to do to “borrow” electricity from your home for your RV.

First, you must realize it is not as simple as just plugging your RV into your home’s electrical system. This will overload your power system, trip the circuit breaker and leave you scratching your head. If you see this as something you may do very often, you want to get in touch with Electric Connection—the electrician Los Angeles residents turn to—and let these experts set you up with an RV to home connection.

There are adaptors available but they will not provide enough electricity to do much other than operate the lighting in your home. You will need to install a long term solution. This is a project that can be done yourself; however, it is strongly recommended that you turn to a professional. It requires extensive wiring work that is not recommended for those not skilled in working with electricity. Essentially, you need a specific circuit that is dedicated to powering your RV.

If you are interested in powering your RV from the electricity in your home, contact Electric Connection today and let us work with you on this project. You will appreciate the experience, expertise and top-notch customer service you receive every time you call Electric Connection.

A power surge is an increase in voltage flowing through your electrical units that rise above the standard voltage levels (120 Volts). These surges can be caused by lightning, high-powered electrical devices (elevators, air conditioners, refrigerators, etc), faulty wiring or even problems with your utility company’s equipment. Inevitably, these are all occurrences that we cannot prevent ourselves, so how can you protect your home and equipment from these damaging power surges?

Surge Protector

A simple solution is plugging in your electronics into a surge protector. A surge protector is a device used to protect your electronics from damaging power surges. However, many people use this tool for a much more obvious function, to plug in multiple components into one outlet, not knowing its protective capabilities. You most likely use at least one surge protector in your home already. But how does it work? How do you know that you are providing the top quality protection for your important devices?

How it Works

As you know, your surge protector pulls electrical currents from one outlet and passes them through all the electrical devices plugged into the surge protector. This aside, the more important feature of this device is its metal oxide varistor (MOV) component, which diverts extra voltage and preventing it from damaging your electronics. This MOV acts in different ways depending on the voltage flow to provide your devices consistent access to adequate levels of power. If the MOV indicates high levels of voltage, it will reduce the resistance and if the voltages are low it will create a higher resistance. However, it is important to be aware that these MOV’s can also burn out. By investing in a power surge with an indicator light you will always be able to determine whether or not it’s functioning appropriately.

In our next blog, Power Surge Protection: What to Look For, we will be discussing how and where to use your surge protector and purchasing tips for finding a quality protector.
