Fall in the Rocky Mountains can be less of a season than a state of mind. The days are warm and sunny while the nights are frigid; that’s perfectly normal in a near-desert climate like Denver. When the days get shorter, it becomes evident that winter is creeping up quickly. And although patients might not be thinking about sunglasses in winter, this is the time we educate them on the importance of a quality sunglass prescription. And a big pre-holiday sale always helps the cause.

In Befuddled by Blue, Part One, we learned that blue light filters that can be used indoors don’t provide a significant reduction in the blue light that disrupts normal sleep patterns. We also learned that the science is not yet available to allow us to conclude that the small dose of blue light emitted from digital device screens is a significant risk to eye health. Yet, we believe that recommending lenses that can be used indoors to reduce high energy wavelengths is a good precautionary measure, as long as the patient is educated on the greatest threat for high energy light damage to the eye, the sun.

Blue light is in the spotlight. You’ve heard the claims…it emits from our digital device screens and is harming our eyes, disrupting our sleep patterns, leading to increased risk of: diabetes, obesity, cancer and behavior disorders. We are alarmed. Consumers are alarmed. We should provide good counsel on the hazards and recommend products that will help, but first let’s shed light (pun intended) on a few of the dizzying array of industry implied and stated claims that have us befuddled.

Spring is an ideal time to bring additional sunglasses into your stock. It is the time of year people are planning vacations; they are spending more time outside at sporting events and exercising, and the amount of time people are around water (pools, lakes, and oceans), increases considerably.

This month, we’re going to take a little blast to the past. In my previous blue blocker articles, I’ve discussed the variety of lens treatments available for day-to-day wear, in order to enhance patient vision, diminish stress, and reduce the likelihood of potential illnesses and disorders later in life, such as AMD. What I haven’t discussed is blue light protective lenses for outdoors.

It is, perhaps, the most frustrating obstacle anyone involved in opticianry will encounter: The blank stare.

Acuity is the acuteness or clearness of vision, which is dependent on the sharpness of retinal focus. That means the clarity of all of the ocular components and their media must transmit and receive light without issue.

Independence, demanded by toddlers, tested by teens and coveted by seniors is significantly affected by vision. After all, independence is a part of each of our ability to earn a living, contribute to society and "drive at night." From a 1999 Canadian Social Trends survey (Catalogue No. 11-008), "The single greatest fear of most older people is that of becoming dependent.

In the last post we discussed the adult eye and how the cornea and lens protect the retina from UVC (skin cancers), UVB (sunburn, blisters, skin cancers) and the UVA (skin aging). Check out more effects that are accumulated over a lifetime and become an issue for each of the senior's anatomical parts of the eye.

In an adult eye, the cornea and lens protect the retina from UVC (skin cancers), UVB (sunburn, blisters, skin cancers) and the UVA (skin aging). UVB and UVC are serious agents of skin tissue changes because the DNA directly absorbs them. The cornea and lens protect the retina by absorbing the greatest majority of radiation.

We are coming into heavy sun season and one of the most important products you should be stocking is sunwear for kids. Somewhere I just read that while 73 percent of adults wear sunglasses, they don't think that sunglasses are important for their kids, because only 30-44 percent of kids wear sunglasses.

Blue light is part of the visible spectrum, the wavelengths perceived as the colors violet-blue to light blue or the wavelengths from about 380 to about 500 nm (Fig. 2). There are three important blue light concerns.
