LIFESTYLE, AGING, AND GENETICS

Uncategorized

More and more studies are showing that the effects of aging can be altered through lifestyle changes in four key areas: diet, exercise, stress management, and social support.  There is now genetic evidence for this and the news is that the genetics can be altered.  Telomeres are parts of our chromosomes that effect aging.  Shorter telelomeres are found in age related diseases but the good news is that by making positive lifestyle changes our telomeres can be lengthened.  Watch the video.

BACK TO SCHOOL; BACK TO THE EYE DOCTOR

Uncategorized

Vision screenings or internet eye exams do not substitute for a comprehensive eye examination.  Visual performance underlies academic performance and a comprehensive eye examination can reveal eye problems that effect reading, comprehension, and learning.  To give your child the best start to a new school year book their eye exam today.

DIGITAL EYE HEALTH

Blog

From childhood through adulthood time spent on digital devices is ever increasing. Computer screens, lap tops, tablets, Nooks, Kindles, and cell-phones all produce a unique visual environment that has many short term and long term effects. Short term problems include eyestrain, headache, visual blur, fatigue, or poor performance as well as physical symptoms such as red, itchy, burny, or dry eyes. Long term problems accumulate over many years of digital device use and include primarily cataracts and macular degeneration.

Fortunately, the risks presented by both long and short term problems created in the digital environment can be reduced with a prescription pair of glasses specifically designed for the digital device distance. This prescription optimizes vision thereby increasing efficiency and reducing eyestrain- the visual system sees and feels better. In addition, special coatings can be added to the lenses that block the damaging HEV (high energy visable) light that is produced by digital devices.

The HEV issue is new, but like SPF for UV protection outdoors, HEV protection will become common knowledge. Even contact lens wearers and people not needing prescription will be wearing protective glasses while on digital devices. My daughter is a food journalist with the Lucky Peach and my son is a molecular biology research tech at the Human Viral Institute at Duke; both spend the entire work day with their face in a digital screen. Neither is dependent on a prescription to see but both wear computer glasses to see better, work more efficiently, and to protect their eyes from damaging HEV light.

The link below provides some interesting insight into the problems created in the digital world.

Digital Eyestrain in Adults

Blog

The Vision Council (thevisioncouncil.org) serves as the global voice for vision care products and services, The Vision Council represents the manufacturers and suppliers of the optical industry. A large part of the council’s service is to educate the public on all aspects of vision. The Vision Council recently released the Digital Eyestrain Report for 2015 wherein it was reported over 90% of adults suffer from digital eyestrain. The report can be found at:

VIDEO OF HOW HUMAN EYE CHANGES FOCUS

Blog

One of the unique features of the human eye is the ability to to change focus from distance to near. The process is called accommodation and was first theorized by Hermann von Helmholtz in 1855. With today’s imaging systems the process can actually be seen. Basically, the lens within the eye becomes more curved and the front of the lens moves forward to create a more powerful lens for near focus. For the science minded, go to http://bit.ly/1rbHuFd. to see the process of accommodation.

THIS IS YOUR SKIN ON SUN
If you’re one of the stragglers who are still ignoring the startling statistics about skin cancer (more than 2 million Americans are diagnosed each year), maybe this video will get you to finally pay attention. Photographer and videographer Thomas Leveritt has revealed what’s lying beneath people’s outer layer of skin. When an ultraviolet camera, which can show not-yet-visible changes to skin, is used, damage that hasn’t yet reached the skin’s surface is suddenly visible.

Likewise retinal imaging allows the doctors to see sun damage inside the eye.
