You need to be extra careful when going to high altitude areas, such as when you may be hiking or what not.  The reason being is because as often is the case in areas with high altitude, the rays of the sun are more powerful with the thinner atmosphere.  I am always surprised that I will get burned more by going into the mountains than by going to the beach.  At the beach I will often wear the appropriate eyewear, whereas in the mountains I am often not wearing the appropriate eyewear necessary to cover up, and essentially to prevent sunburn.  

I don’t know if you guys have ever had a sunburn on your eyes, but they seriously are the worst you could ever imagine.  They affect the whole areas around the eyes, and they can certainly make your life miserable.  I know that the last time I had a sunburn, my eyeballs itched like crazy, and it seemed even with the addition of eye drops, my eyes were still unbearable, and it seemed like it lasted forever until the healing process began.  I can’t believe how sensitive the eye can be, and it makes me appreciate having my sight in general.  I hope and pray that I always have great eyesight.
