Facts About Blue Light

Most people have heard the new danger from light is Blue Light.  So here are the facts as we know them currently.

Blue light¬† is deeper penetrating on the eye than UV(ultra violet), thus meaning that while UV damages the front surfaces of the eye, blue light enters the eye and attacks the retina.¬† Sunlight is 25-30% blue light.¬† Blue light is split into blue-violet(415-455nm) and blue turquoise(465-495nm).¬† The blue violet does damage to the eye, while blue turquoise stimulates pupil reflexes , regulates sleep patterns, and promotes good health in general. Blue violet cause retina, choriod¬†, fovea and optic nerve damage. This blue violet light¬†causes¬†the maximum¬†retinal cell damage and cell death.¬† This also increases AMD(age-related macular degeneration).¬† The exposure¬†is accumulative.¬† New energy saving¬†lights such as LED and CFLs¬†increase the amount of blue light we are exposed too.¬† Todays modern gadgets such as LED monitors, tablets, flourescent¬†lights and smart phones all contribute¬†to the elevated risk,¬† the risk is even higher for individuals¬†who smoke.¬† Cutting out all blue light isn’t the answer because you need the blue turquoise like to stimulate brain functions, alertness, memory, emotions and cognitive performance.¬† The optical industry is studying and looking for solutions for this blue violet light problem.¬† Several company’s¬†have come out with coatings that help eliminate¬†our exposure to this bad light and let the good blue turquoise light keep us healthy.

Hot New Eyewear Material

Ultem Eyewear
TR-90, also known as Ultem¬†is a new comer to the eyewear material list. It is a thermoplastic used by many industries because it is light weight, flexible and durable. Extreme temperatures do not affect this material unlike other plastic eyewear options. This temperature feature is very beneficial in the Texas summer heat when you glasses get left in the car. Zyl¬†or acetate eyeglass frames left in the car during the summer get very soft and out of shape easily. This material can be made into many colors and have either a glossy or a matte finish. This eyewear material also doesn’t fade with time like other types of plastic. It also doesn’t absorb chemicals such as make-up or hair dye.

This means that eyewear made of TR-90 is very light weight, very flexible and has a large selection of shape, sizes and colors. All of these features together make this eyewear fun to wear and be seen in, while being durable enough to be active in.

Vinyl Factory – Garside Sunglass

Vinyl Factory Garside Sunglass
Meow… The hot look this summer is a modern twist on an old classic.¬† The cat eye has returned and is trending!¬† Eyeglass stylist are seeing different versions of the cat eye style in sample cases of many eyeglass manufacturers reps.¬† One of my favorite eyeglass pieces is a frame from R&R Eyewear out of their Vinyl Factory collection called the Garside.¬† The frame is named for KatieJane Garside an English rocker in the popular UK group Daisy Chainsaw from the 90’s.

“Spex & mugs & rock n’ roll” is the motto for the eyewear line and is printed on each one of their frames.¬† In fact, I loved it so much I had to have one for myself.¬† It is fashionable, fun and a true wearable art piece that will catch a ton of attention.¬† The frame is metal covered in a rubberized material giving the eyewear piece a truly unique look and velvety texture.¬† The part of the temple that goes behind the ear resembles a guitar handle, which I found comfortable and functional as it kept the sunglasses from becoming loose.¬† I got it in an eye catching hot pink which is bright and vibrant.¬† The Garside comes in other colors including a classic black.¬† The added bonus with this sunglass is that it comes with polarized lenses which means you can walk out of the store with it and head to your favorite poolside or vacation destination.¬† As with any top quality eyewear it is RX able and will hold most prescriptions nicely.
