Alcohol’s Effects on Night Vision

We all know that alcohol impairs judgment and coordination and slows reaction time.
But here is yet another reason to cut back on your alcohol consumption: A study coming out of the University of Grenada has shown that overconsumption can also adversely affect your night vision. The study examined 67 subjects who had consumed various quantities of wine. The researchers used a “halometer” visual test to determine the level of night vision disturbances and optical image quality. What they found was that the greater the breath alcohol content level, the greater the visual disturbance.

Alcohol disturbs the tear film that covers the surface of the eye. The ethanol (intoxicating agent) present in alcoholic drinks disturbs the outer tear film layer, causing the aqueous part of the tear to evaporate. When tear film is disturbed, the image quality that forms on the retina is also negatively affected, leading to the presence of halos and other visual disturbances in night vision.

Now add into the equation a pre-existing vision condition, such as nearsightedness, farsightedness or astigmatism. If your vision is already impaired due to a refractive error and you consume alcohol, the tear film disturbance combined with poor choices (such as not wearing glasses or contacts) can lead to disastrous consequences for yourself and others. LASIK vision correction in Longmont can correct these types of refractive errors, but even having 20/20 vision will not reduce the negative effects of alcohol on your vision.

In the past, some LASIK patients also complained of night vision problems after their procedure; however, today’s LASIK technology has effectively reduced this type of complication of LASIK. To learn more about Longmont LASIK and find out if you might be a good candidate for the procedure, contact Eye Care Center of Northern Colorado at 888-702-1188 or eyecaresite.com. And whether or not you have LASIK, please never drink and drive.

Are You Photo-Happy on Facebook?

A 2013 study out of the UK showed that uploading too many photos of yourself to Facebook, including ‘selfies’, can make people like you less. However, Facebook also made changes in 2013 to its news feed to make room for larger pictures. The fact is that people do like to see photos of their friends, family, co-workers and old school chums on social media. It’s probably the number one reason why so many people flock to Facebook and sites like Instagram (although we can’t scientifically back this statement up).

The question is: Do you like how you look in the photos that you post – or the ones that others post of you? Are your glasses taking center-stage in your photos? Is there always glare coming off your lenses?

While these may seem like insignificant reasons to have a vision correction surgery, consider this: LASIK in Longmont may help you gain more self-confidence in front of the camera or smart phone lens. Our doctors at Eye Care Center of Northern Colorado has helped thousands of patients correct their nearsightedness, farsightedness and astigmatism through LASIK procedures. If you want to find out if you can get rid of your glasses and contacts, our doctors offer free LASIK Consultations in Longmont to tell you more about the procedure and help you find out if your eyes are right for LASIK.

So, if you don’t want to turn off your friends and family on Facebook, post less photos of yourself. However, we will warn you that after LASIK, your appearance without glasses may have your face showing up on Facebook more often. But we feel it’s worth the risk.
