Until recently, I hadn’t given much thought to what it actually means to have 20/20 vision. Like most people, I assumed that 20/20 vision was just a synonym for “perfect” eyesight. But when I recently spoke with optometrist Graham Erickson, a sports vision specialist, I realized that there is an entire medical field devoted to optimizing vision for athletes – so that they can see better than 20/20, perhaps even 20/8! In fact, 20/20 vision just means that you can see an object 20 feet away as well as the “average” person.
In my interview with Dr. Erickson, I learned that some professional baseball players have vision that is two times better than average, allowing them to judge pitches further away by seeing how the baseball’s stitches and seams turn in mid-air. This kind of vision is not necessarily something that you’re born with – it can come with training and good vision-correcting lenses. There are exercises that professional do to improve their contrast sensitivity, peripheral visual acuity, and reaction times. And we regular folks (weekend warriors, kids, and aspiring athletes) can also “pump up our peepers” with exercises that we can do at home. Please listen in to the full Healthy Vision segment to find out how to do these exercises:
I also learned that different athletes (such as basketball players, archers, and offensive linemen) have unique visual demands, and they train for those demands quite differently. While a basketball player may focus on improving his “court vision” (dividing his attention between guarding “his man” and being aware of what’s going on in the periphery), an archer may rely almost exclusively on her central vision,
while an offensive lineman may need to split his attention between central near vision (controlling his man) and peripheral vision to pick up shifts by the defense. Since it’s estimated that 80% of the information we take in (while playing sports) comes from our eyes, even slightly blurry vision can dramatically affect performance.
Even though there is a lot that athletes can do to improve their visual skills, very few competitive athletes get annual comprehensive eye exams. In my latest Healthy Vision episode, NBA star Tyreke Evans* offered a call-to-action to his peers regarding regular check ups, and World-Champion female sprinter Allyson Felix spoke to me about the role that good vision has had in her success.

In summary, I learned from Dr. Erickson and Allyson Felix, that eye fitness is a critical part of competitive sports, but unfortunately something we often don’t think about. There are new training programs that help to develop peripheral vision skills that may reduce the risk of being blind sided in football or hockey games, and can therefore reduce concussion risk. Athletes should seek out an eye care professional who specializes in sports vision in order to optimize their visual potential. The American Optometric Association’s Sports Vision Section offers a doctor locator to help patients find sports vision experts in their area.

When I asked Meaghan Martin (star of Mean Girls 2, 10 Things I Hate About You and Camp Rock among others) what was the most difficult thing about being a teen these days, she didn’t hesitate: “Being a teen has always been difficult, but today there are so many ways to be rejected. Between Facebook, Twitter, and other online sites, it seems as if every day there’s a new way to be un-friended, excluded, or picked on.”
I interviewed Meaghan about her perspectives on teen self-esteem issues and the impact that physical appearance can have on young men and women. You can listen to the edited interview here (starts at minute 12:02):
The most striking thing about Meaghan is that she is a genuinely nice person. Down-to-earth, confident, empathic – she exudes an inner peace that is downright wholesome. How did she escape her teen years relatively unscathed by hormonal angst, I wondered? The secret, she said, was loving parents.
“I was a typical nerd as a kid. I had glasses, braces, and an asthma inhaler. But I didn’t care what others thought of me, because my parents told me that I was a good person who could do anything I wanted in life. They taught me self-confidence, and supported me 100% in anything I wanted to do. I was so blessed to have parents like that.”
I chuckled as I remembered my pre-teen and teen years, sharing with Meaghan that I was a lot like her – except that I had traded the asthma inhaler for acne. For me, Read more »
Attention-deficit/hyperactivity disorder (ADHD) is probably overdiagnosed by physicians. In the lay public, the term is often used jokingly to describe the common feeling of distraction we experience in a world filled with interruptions. With a constant stream of text messages, Facebook updates, TV commercials, and fast-paced Twittering, there’s little wonder that we all feel frazzled at times.
But the occasional experience of jangled nerves is not a proper basis for a diagnosis of ADHD. Unfortunately, there has been great confusion between the actual disorder, and its misuse as a label for simply feeling distracted.
So to help set the record straight and to tease out fact from fiction, I’ll be attending a forum on Capitol Hill with my co-bloggers Dr. Kevin Pho and Dr. Rob Lamberts.
If you’re in the DC area, please come and join us in person. If you’d like to view some of the event via the Internet, we’ll be conducting live interviews with the speakers on Ustream. You can join the conversation by asking your questionsin real time in the chat room starting at 2:00PM (EST) on Thursday, September 16, 2010.

It’s not every day that a physician is invited to be screened for chronic obstructive pulmonary disease (COPD) by a comedian. But this event was no joke – actor Jim Belushi is in a contest with Danica Patrick, Bruce Jenner, Patty Loveless, and Michael Strahan to see who can get the most Americans screened for COPD. It’s a tough race for a good cause – though I’m not sure if Jim stands much of a chance in a competition against Danica Patrick. Maybe my blog readers will vote for Jim and give him the bump needed to keep him in the running? Please take the screening test here, or forward it to friends who may be at risk (age over 35, history of smoking).
Like any good blogger, I had my trusty digital recorder with me and got in a few questions with Jim. Special thanks to South African blogger Delre Roberts, who gave me the idea for my leading joke to Jim via Facebook: “How’s a comedian going to screen a doctor for COPD? See how short of breath she gets from his jokes?” Good one, Delre! You got a laugh out of Jim… Check it out:

Susie Essman, aka Susie Greene of Larry David’s HBO program, “Curb Your Enthusiasm,” has written a hilarious book (and yes, I actually read it) called What Would Susie Say?: Bullsh*t Wisdom About Love, Life and Comedy. For this week’s CBS Doc Dot Com, I talked to Susie about some of her health issues covered in the book, including menopause, fear of germs, and hypochondria. “So far this month,” she told me, “I’ve had Lyme disease, hysterical blindness, enlarged prostate….”
If any woman could actually have an enlarged prostate – either her own or snatched in a fit of pique from her beleaguered television husband played by Jeff Garlin – it would be Susie Green. But as we discussed her real and imagined symptoms, it became clear that Susie Essman can be easily talked down from her flashes of hypochondriacal thinking. So she doesn’t actually meet the official psychiatric definition of “hypochondriasis,” in which a misinterpretation of symptoms leads to a preoccupation with having a serious illness that interferes with daily functions and lasts at least six months despite reassurances from a doctor. In fact, her belief that she’s a hypochondriac is hypochondriacal. Read more »
