Don’t Let Snow Blindness Ruin Your Winter Vacation

While most people have sunglasses high on their packing list for a tropical vacation, many people don’t consider it as much of a priority for colder climate getaways. But they should, and here’s why:

Wintertime vacations often include activities that involve snow and ice and in general, conditions that can lead to overexposure to UV rays from the sun. Without proper eye protection, this can lead to photokeratitis or snow blindness, a condition that results in pain and temporary vision loss.

Photokeratitis is essentially a sunburn on the eye which occurs when the eye is exposed to invisible ultraviolet or UV rays, from the sun or other sources such as sun lamps or tanning beds. It mainly affects the cornea, the curved outermost surface of the eye that plays a role in your ability to focus, and the conjunctiva, the membrane that covers the front of the eye and lines the inside of the eyelid. It causes inflammation, pain and sometimes a temporary loss of vision.

Despite its name, snow blindness doesn’t occur exclusively in the snow. It can happen in any environment in which UV rays are strongly reflected including water, sand or ice as well. It is also more common in high altitudes where the sun’s ultraviolet rays are stronger and the air is thinner, which is why skiing and mountain climbing can even be more risky than summertime activities on a lower altitude. Snow and ice reflect more UV light than almost any other surface, but you don’t always feel or notice the strong glare, making snow blindness a silent winter hazard that can only be prevented by awareness.

Symptoms of Snow Blindness

Unfortunately, just like any sunburn, you usually don’t notice the symptoms of snow blindness until the damage has already been done. Symptoms usually occur several hours after the activity, so one may not realize that they were caused from snow blindness.

Symptoms include:

  • Pain
  • Burning
  • Redness
  • Grittiness
  • Tearing
  • Light Sensitivity
  • Glare or Halos
  • Blurry Vision
  • Watery Eyes
  • Swollen Eyes or Eyelids
  • Headaches
  • Temporary Vision Loss

Any vision loss that does occur will usually return with in a day or two, but the greater the exposure to the UV rays, the worse the damage that is done.

How Is Snow Blindness Treated?

There is little to do to treat photokeratitis. Just like a sunburn elsewhere on the body, it eventually heals on its own. There are however, some steps you can take to find relief from the symptoms which include:

  • Stay indoors, in a dark area until the eyes become less sensitive.
  • Wear sunglasses if it helps.
  • Avoid rubbing your eyes.
  • Remove contact lenses.
  • Apply preservative-free artificial tears to add moisture.
  • Use a cold compress to soothe your eyes.
  • Try over-the-counter pain relief or antibiotic eye drops according to your eye doctor’s advice.

If your symptoms worsen or don’t improve within 24 -48 hours, contact your eye doctor immediately.

Tips to Prevent Snow Blindness

Snow blindness is actually very preventable and all it takes is a good pair of sunglasses or sports goggles. Any time you are outside, rain or shine, you should wear 100% UV blocking sunglasses. That’s right, the sun’s powerful UV rays can even penetrate clouds on an overcast day.

If you are involved in sports such as skiing, snowboarding, mountain climbing or water activities consider a pair of wrap-around sunglasses or sports goggles with shields to prevent the rays from entering from above and through the sides. Wearing a hat or helmet with a brim will also help to increase protection.

Whether you are going North, South or somewhere in between, make sure to pack your shades and protect your eyes so you have an eye-safe, fun and enjoyable vacation.

PROTECTING OUR COMMUNITY

We have been working very hard to prepare to re-open for normal "routine" preventive eye care, taking every precaution to ensure the safety of everyone involved. We are pleased to announce as of Monday May 18th we'll be seeing patients for all types of eye care, including routine annual eye exams.

But, things will be very different than they were prior to the pandemic.

1. Our front door will be locked at all times. We will be allowing only 1 person at a time in the office and by appointment only, so please enter alone, or with no more than l other person accompanying you. Others may wait in the car.

2. Masks will be required for both patients and us while in our office.

3. Upon entering, we will be checking your temperature and screen you for COVID symptoms or possible exposure. If your temperature is 100 F or higher, or you have symptoms or may have recently been exposed to COVID, we will reschedule you.

4. We will need you to respect the 6 feet personal distancing while outside the exam room

5. We will have you wash your hands for 20 seconds or use hand sanitizer when you enter. We will be using hand washing and hand sanitizer constantly and will be disinfecting everything you and we touch. Please don't touch anything that isn't absolutely necessary.

6. For frame selection or picking out glasses, please let us help you, and don't just browse and try on frames by yourself. We have to disinfect the frames every time they are touched or worn, and we need to know which frames need to be disinfected.

We are doing all these things to protect you and all of our other patients as best we can. We will need and depend on your cooperation on this during this very difficult time. Doing so will protect your fellow patients-many of whom are at extremely high risk if they contract COVID - and to protect us. All healthcare providers are putting themselves in harm's way every day during this pandemic - the more we all cooperate and take appropriate precautions, the better off we all will be.

We are all in this together. Thank you for your patience, understanding, and cooperation.

Please stay safe.
