The Danger Of Blue Light And Cataracts
For many years, eye care professionals and researchers in the field of opthalmology have warned about the dangers of Blue Light on the eye. It is well documented that exposure to Blue Light is a direct cause of Adult Macular Degeneration (AMD). But it has also been understood that cataracts, which in some ways protect the eyes by lessening Blue Light exposure, reduced the development of AMD. However, new research is making a link between surgery to remove cataracts and an increased risk of AMD.
At a discussion held during the 1st World Congress on Controversies in Ophthalmology (COPHy) in 2010, research results were presented that concluded a direct link between dry AMD progression following cataract surgery. The study, conducted at Kaplan Medical Center at the Hebrew University in Israel, described a rapid progression of AMD post-surgery.
While both cataracts and AMD are common in senior adults, the progression of these diseases is increased by exposure to Blue Light. And in the instance of those who develop AMD post-cataract surgery, the study concluded, it is essential to weigh the pros and cons of exposure to Blue Light, taking into account the increased risk of developing or worsening AMD.
According to Dr. Deepinder K. Dhalieai, MD, associate professor of opthalmology and chief of refractive surgery at the University of Pittsburgh, the data collected from these and other studies concerning the development of AMD, there was a significant link between exposure to Blue Light after cataract surgery and the risk of developing AMD.
Lessening exposure to Blue Light after cataract surgery is essential in lowering the risk of AMD. So what can you do to lessen your risk? Take these three steps:
Blue-Filtering Lens Implants
Patients should consult with their surgeon regarding the implantation of Blue-Filtering IOLs (intraocular lenses) at the time of cataract surgery.
Blue Blocking Sunglasses
Wearing eyeglasses or sunglasses that block Blue Light is also essential in reducing AMD risk. The Uvex S0360X is a great choice for home use because they fit over prescription glasses.
Change Your Lighting
Patients should also remove Blue Light within their home environment. Simply replace CFLs (compact fluorescent lamp) or standard light bulbs with The Good Night Light by Definity Digital, which produces no blue light, but still casts a normal white light.
