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.

Why Alcohol Affects Vision

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.

Pre-existing Vision Conditions

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 Charleston 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 Charleston LASIK and find out if you might be a good candidate for the procedure, contact Charleston Cornea & Refractive Surgery at 843-856-5275 or charlestoncornea.com. And whether or not you have LASIK, please never drink and drive.

·      And more…

      At Charleston Cornea & Refractive Surgery, we would never recommend a person have LASIK just because a certain celebrity has done it. This is not a decision you should enter into lightly, and you should only pursue it with a highly qualified and trained ophthalmologist. In fact, not every person is a good candidate for LASIK. Dr. O'Day performs a comprehensive LASIK exam in Charleston to assess every potential LASIK patient’s corneal thickness, overall eye health and medical condition before giving the green light for LASIK. The process begins with a free LASIK Consultation where you can learn more about your eye anatomy and ask questions about the procedure, the LASIK technology that will be used and the surgeon’s track record of success.

If you want to pursue a life with the possibility of lens-free vision like so many celebrities have, contact Charleston Cornea & Refractive Surgery today to arrange your free LASIK Consultation. Call 843-856-5275 or visit charlestoncornea.com to schedule your appointment online anytime. We can’t promise you’ll end up on the big screen, but you may be able to watch your favorite celebrities without the hassles of glasses or contacts!

Will School Make You Nearsighted?

Researchers in Germany have uncovered a possible link between spending more years in school and the prevalence and severity of nearsightedness. In the Gutenberg Health Study, they looked at 4,658 Germans ages 35-74 who had myopia (nearsightedness), which causes distant objects to appear blurry while close-up objects are clear. The study did not include participants with cataracts or anyone who had refractive surgery.

The Findings

• 53% of university graduates had myopia
• 39% of high school graduates had myopia
• 24% of participants without a high school education had myopia

The myopia became more severe with each additional year of school.

Don’t Sacrifice Education for Vision

We are not recommending that people drop out of school to possibly protect their vision. Instead, while you are pursuing your education, be aware of your environment and how it is affecting your eyesight. For example, take frequent breaks from your computer and give your eyes a rest.

Another Reason Why Recess is Important

If these findings are valid, it makes sense for students to increase their time outdoors…making recess an important part of the school day (regardless of your level of education).

Already Nearsighted? You Have Options

Of course, people can have myopia regardless of the amount of schooling – you can be born with this condition where your eye is too long or too steep, causing light rays to focus in front of your retina rather than on the surface. If you are already nearsighted, you have options to correct your vision, including LASIKvision correction in Charleston. This quick and virtually painless procedure uses a laser to microscopically reshape the cornea so light will focus on the retina (the back of the eye) and clear vision can be obtained.

To learn more about your own vision characteristics and find out if LASIK technology in Charleston may help you see with 20/20 vision, contact Charleston Cornea & Refractive Surgery by scheduling your free LASIK Consultation at charlestoncornea.com or by calling 843-856-5275. 

Choose Sunglasses Wisely

One of the top benefits that LASIK vision correction provides is the opportunity to wear any type of sunglasses you want. Patients who achieve 20/20 vision after LASIK are usually excited to get rid of their expensive prescription sunglasses and start choosing a variety of fashionable sunglasses off-the-rack.

While most people know that it’s important to wear sunscreen with a high SPF to protect their skin from sun damage, few worry about UV protection in their sunglasses. The fact is that UV radiation can lead to serious eye problems, including cancer, cataracts, macular degeneration, painful sunburns of the cornea (photokeratitis) and damage to the eye lens and other parts of the eye. You should wear sunglasses any time you are outdoors – even in the shade, even in winter, even if you wear contact lenses that block UV rays.

At Charleston Cornea & Refractive Surgery, we not only help people achieve better vision through our advanced LASIK technologies in Charleston, we also want our patients to keep their eye health a priority after LASIK. When choosing sunglasses after LASIK, it’s important to look for UV protection details on the labels and choose shades that provide 100% UVA and UVB protection. The color and darkness of the lenses has no impact on the amount of protection. Frames that wrap around and cover the sides of the eyes are also beneficial in protecting your eyes from harmful rays. 

This subject is so important that scientists in Brazil have developed and installed a free self-serve sunglass UV testing kiosk in San Carlos so people can test how well their sunglasses block UV rays. In a test of 800 users of the kiosk, 20% found their sunglasses provided inadequate protection. If you are unsure about your own sunglasses, talk to your optician, optometrist or ophthalmologist or invest in a new pair of sunglasses that meet the right requirements.

Get More Enjoyment from 3D Movies

Movies, televisions and even theme park rides in 3D really help to bring the action to life. Of course, in order to get the full effect of 3D experiences, the viewer must wear special 3D glasses. In fact, if you view a 3D movie without the glasses, the blurry image on the screen can be very uncomfortable on your eyes.

     If you currently wear regular eyeglasses for nearsightedness (myopia) in Charleston to see distant objects clearly, going to a 3D movie can be a real hassle. You have the options of:

• Wearing 3D glasses over your regular eyeglasses (this is also uncomfortable)
• Wearing contact lenses instead of your regular eyeglasses (although not everyone can wear contacts)
• Purchasing special 3D clip on glasses that you wear over your regular eyeglasses to watch 3D movies (you have to remember to bring them with you)
• Watching the alternate 2D version of movies instead of the 3D version (and miss out on some special effects) 
• Having LASIK vision correction to possibly correct your myopia and eliminate your need for glasses 

Dr. O'Day at Charleston Cornea & Refractive Surgery has performed thousands of LASIK procedures on myopic patients. While not all of them have been fans of 3D movies, they all wanted to find out what life could be like if they didn’t have to wear glasses or contacts. Most of them didn’t enter into the decision to have LASIK lightly. They researched the LASIK process in Charleston. Then they learned if their eyes were right for LASIK (through a free LASIK Consultation at Charleston Cornea & Refractive Surgery) and interviewed Dr.O' Dayextensively to make sure he had the best experience, the best LASIK technologies and best “chair-side” manner. 

There are a lot of 3D movies coming out in spring/summer 2014: How to Train Your Dragon 2, Transformers: Age of Extinction; Maleficent, Godzilla, Teenage Mutant Ninja Turtles, Guardians of the Galaxy and more. If you would like to have a more enjoyable 3D summer, find out if Charleston LASIK vision correction is right for you.
