Coffee has been shown to help in the prevention of deteriorating eyesight and possible blindness from retinal degeneration due to glaucoma, aging and diabetes. According to a study by Cornell University, coffee contains 7% to 9% chlorogenic acid, a strong antioxidant that prevents retinal degeneration in mice.
The study, published in the Journal of Agricultural and Food Chemistry states, “The retina is a thin tissue layer on the inside, back wall of the eye with millions of light-sensitive cells and other nerve cells that receive and organize visual information. It is also one of the most metabolically active tissues, demanding high levels of oxygen and making it prone to oxidative stress. The lack of oxygen and production of free radicals leads to tissue damage and loss of sight.”
In the study, mice eyes were treated with nitric oxide, which creates oxidative stress and free radicals, leading to retinal degeneration, but mice pretreated with CLA developed no retinal damage.
The study is "important in understanding functional foods, that is, natural foods that provide beneficial health effects," Chang Lee, professor of food science and the study's senior author, said in a statement. "Coffee is the most popular drink in the world, and we are understanding what benefit we can get from that."
Coffee has also been shown to cut the risk of such chronic diseases as Parkinson's, prostate cancer, diabetes, Alzheimer's and age-related cognitive declines. So go out and visit one of the many amazing locally owned coffee shops in Reno Tahoe, and enjoy a cup of Joe!
Dr. Rowan was on KRXI Fox 11 Reno this week talking about the Military Hero of the Game initiative we support. We're looking for nominees that we can honor during Nevada Wolf Pack home football games. If you know of an active or retired member of the armed forces that you'd like to see recognized during a game, please nominate them today! Nominations are accepted at: http://nevadawolfpack.com/militaryhero.
Unless you’ve been living on the moon, you’ve likely heard that this coming Monday morning, August 21st, there will be a solar eclipse, a rare event when the moon passes between the sun and the Earth blocking Earth’s view of the sun. The last time we had a total solar eclipse in North America was in 1979 and the next expected eclipse will be in 2024.
While the solar eclipse is super exciting and here in Northern Nevada we’ll see about 83% of the sun blocked, we need to keep in mind that viewing eclipses can be damaging to our eyes. We urge you to obtain a pair of viewers designed specifically for viewing an eclipse. Looking at the eclipse without the viewers, or even standard sunglasses, can cause significant damage to the eyes.
While in Reno/Sparks we’ll only be able to see about 15% of the sun, that is enough to cause permanent eye damage. Even taking quick glances at the sun can still be harmful.
The damage that can occur is called solar retinopathy and it occurs when the bright light from the sun floods the retina on the back of the eyeball. Essentially, the sun can burn a hole in your retinal tissues which can be permanent or temporary. The damage is often painless so people don’t realize what they’ve done.
It can often take a few hours or a few days after viewing the eclipse to realize you’ve done damage. Symptoms can include; loss of central vision, distorted vision, or altered color vision. If you notice any of these after Monday’s eclipse, be sure to give us a call.
So, of course, the safest best is to use the safety viewers created for this event. But, we know that these are hard to come by now. Other options for safely viewing the eclipse include looking through Number 14 welder’s glass, making a pinhole projector (check out this video on how to make a projector using a pizza box), or attend one of these local eclipse viewing parties in Reno, Tahoe and Carson City.

How often have you grabbed a tissue or used the bottom of your shirt to clean your glasses? I think we've all been guilty of one of those if we wear glasses.
Let Donna, one of our Opticians in our Northwest Reno office, show you the correct way to clean your glasses. Don't have any eyeglass cleaner or need a cloth? No problem! Stop by one of our offices in Reno, Carson City or Tahoe and we'll gladly give you some.
One of the most common questions our eye doctors are asked is “When should I bring my child in for their first appointment with you?” Many parents think the first eye exam should take place when their child starts school, but it’s actually recommended to come in for a first appointment before your child turns 1, and then annual exams after that.
Eye exams for infants are very important, and we make sure they’re both quick and easy for you and your child. During this visit, our doctors will check the basic working order and structure of the eyes to make sure they’re developing properly. They’ll also check that the eyes are working well together and that they’re free of rare but serious problems, such as cataracts and tumors that could hinder vision. We recommend scheduling your appointment before your child turns 1, however, if after age 3 months you notice any of the following, we recommend calling us to get in as soon as possible:
Between the ages of 2 and 3 our doctors will check for signs of developmental eye problems, like “lazy eye,” crossed eyes, nearsightedness, farsightedness and astigmatism. If we find a problem we can recommend corrective therapies. We also work closely with local pediatric eye care specialists if more aggressive treatments, such as surgery, are required.
Just before Kindergarten we will check for visual acuity and prescribe glasses if needed.
Once your child starts school, a yearly eye exam continues to be a must - kids who don’t see well, don’t learn well. Children’s eyes can change quickly, and before you know it, their schoolwork can suffer. The good news is that most conditions can be easily corrected, once they’re detected.
If you haven’t brought your child in for their first exam, give us a call at any of our four locations; West Reno, South Reno; Carson City or South Lake Tahoe, and we’ll get you in soon to see one of our great doctors. We’ll even have a treat for your little one when we’re done!
When it comes to glasses and kids we often see three scenarios in our offices. The first is a child who is complaining about blurry vision either when reading books or looking at the whiteboard in their class. Through testing, we can determine that your child does in fact have a vision problem and we can prescribe appropriate glasses, or contacts for older children.
The second is a child who is also complaining about not being able to see in class and is certain they “need” glasses. In this case, we sometimes determine he or she doesn't need glasses, and instead diagnose a case of “I just really want to wear glasses because I think they’re cool.” In this case, we carefully talk to the parents and let them know that their child’s vision is fine and that glasses aren’t needed. We then present this to the child in a way as to not upset them.
The third scenario is the child who comes in and says that everything is fine with their vision, but during our testing we realize that glasses are definitely needed.
So how do you know if your child needs eyeglasses? The only way to know for sure is to make schedule a yearly eye exam for them. Like everything else going on with their little bodies, their eyes can change seemingly overnight. Thanks to annual eye exams, our doctors can keep tabs on vision changes.
In between those yearly eye exams, here are some things to watch for:
If you believe your child may need glasses, or you haven’t brought them in during the past year, please give us a call so we can get an appointment scheduled for them. We offer a large selection of glasses for children of all ages, from infants to teens. And, our experienced opticians can help you decide if you’d like to add protective coatings or transitional lenses that convert the glasses to sunglasses.
