Eyelid Cancers – Get Our Those UV Sunglasses!

people_sunglassesWe all know the damage that the sun’s UV exposure can do to our bodies.  Repeated research studies demonstrate a clear association between eye damage (cataracts and macular degeneration) and excess UV high energy light.  Wearing UV sunglasses help with protecting our eyes in those areas.  However,  many people do not realize the damage UV exposure can do to the delicate eyelid tissue around the eye.  Sunscreen around our eyes generally stings as it heats up and runs into our eyes. As a result, our delicate eyelid skin and the areas adjacent to the eye are left unprotected.

Its an amazing statistic  – – 10 percent of ALL skin cancers are on the eyelids!

caner6This is another major reason to make sure you wear not only UV sunglasses for your eye but that your sunglasses are large enough to cover the unprotected area around your eyes where sunscreen is not applied.  Also,  wrap around sunglasses are most effective in blocking UV rays from entering the eye

cancer5C. William Hanke, MD, senior vice president of The Skin Cancer Foundation. “With their thin, delicate structures, the eyes and surrounding areas are particularly prone to cancers. And it’s an area people often forget to protect from the sun.”

While only a small number of basal cell carcinomas,  squamous cell carcinomas, and melanomas are lethal, eyelid skin cancers can cause significant tissue damage and blindness, and can spread into the nasal and orbital cavities (the area behind the eye).

cancer2More than 90% of eyelid cancers are basal cell carcinomas (cancer) of the skin. The lower eyelids are involved in more than 70% of cases.  These tumors usually do not spread to other areas of our body fortunately.  However, squamous cell carcinomas and melanomas can easily spread elsewhere into vital organs of our body.

cancer4Early warning signs include:

  • a lump or bump that frequently bleeds or does not disappear
  • persistent red eye or inflammation of the eyelids that does not respond to medication
  • newly acquired flat or elevated pigmented lesions that have irregular borders and growth
  • unexplained loss of eyelashes

Experts recommend wearing hats, sunglasses, and sunscreen to protect the eyes and eyelids from damaging rays.  Some makeups have UV protection and may be safe for around the eyes also. Sunscreen is also recommended where it can safely be applied.

If you wear a prescription in your eyeglasses for distance, then its important to get a good UV protecting pair of sunglasses in your prescription not only to protect your eyes but protect the delicate tissue around the eyes.

New First Choice Treament for Glaucoma

SLT Laser GlaucomaFor many years, people who have been diagnosed with glaucoma have had to use drops to reduce their eye pressure to preserve their vision.  Sometimes, not only 1 drop but 2 or 3 different types of eye drops used 3 or 4 times a day.  Not only is this time consuming, but often in our busy day, people forget or perhaps not a complete drop gets into their eye.

Now, a new variation of laser treatment for glaucoma has arrived.  Though lasers have been used to try and open up the drainage canal where fluid inside the eye can flow (trabecula meshwork), these lasers have had side effects and sometimes unpredictable.  Now there is a new treatment called  selective laser trabeculoplasty (SLT) as primary therapy for glaucoma.

According to Lawrence F. Jindra, MD.  “SLT has less energy than the average laser used to scan groceries at the checkout”.  So it treats the trabecular meshwork without causing thermal or coagulative damage but allowing for clinically effective repeatability.”

This is a fantastic new therapy which will help preserve vision in people with glaucoma or people who are suspected of high probability of developing glaucoma in the future.

Science Baffled By Optical Illusion

illusionThere are many optical illusions .. and I think we’ve all seen some pretty amazing ones at times.  Most illusions can be explained by the retinal neurology and known algorithm that the retina deals with information it receives.  However, this illusion has yet to be explained.  Notice that ‘black dots’ appear randomly as you look around.  Those ‘black dots’ are really not there.  Have fun!

Our Car Addictions – ‘Un’-Plugging Along

Formula E QualcommElectric cars have been around for since the 1830’s.  Yes, that’s not a typo … over 180 years ago electric  vehicles were cruising down the streets, or hay fields.electric vechicle  Now in 2013, we are once again revisiting the electric car as energy conservation becomes more important.  Formula 1 car racing is the fastest and most technical of all auto racing.  Next year, the F1 organization will have Formula E .. all electric race cars.  

By putting electric race cars on the track, its is hoped that public opinion and desire for electric cars will increase.  Certainly electric vehicles are seen as less powerful and limiting.  Tesla Automotive  has risen to the occasion to also demonstrate that electric vehicles can be exciting.Hopefully, things like Tesla and F1 – Electric racing will promote change and stimulate companies to keep pursuing new innovations which ultimately may greatly change the face of our automotive energy world.
