Snowblind—it's a frightening word. Thankfully, it's a condition that is totally preventable.
Snow blindness is a painful, temporary loss of vision due to overexposure to the sun's UV rays. Essentially, snow blindness is caused by a sunburned eye.
Though it is commonly called snow blindness, the condition can (and often does) occur in the absence of snow.
The terms “snowblind” and “snow blindness” have become popular because snow is highly reflective of ultraviolet radiation. Also, skiing, mountain climbing and snowboarding usually take place at relatively high altitudes, where the sun's UV rays are stronger. Combined, these factors can double your risk of getting sunburned eyes, compared with being outdoors at lower altitudes in the summertime.
Television journalist Anderson Cooper experienced snow-free snow blindness first-hand a few years ago when he spent a couple hours on a boat in Portugal without sunglasses and ended up “blind for 36 hours,” according to his report of the incident.
Not only can you become snowblind without snow—it can happen without sunlight, too! For example, sun lamps can cause temporary “snow” blindness if proper eye protection is not used.
To relieve pain or discomfort from snow blindness, stay indoors and wear sunglasses. Keep your eyes well-moistened with artificial tears. For additional relief, use over-the-counter pain relievers. Be sure to use only pain relievers you know you can take without worry of an allergic reaction. You also may find that placing a cool, dampened washcloth over your closed eyelids is comforting.
A. You don't need snow to become snowblind.
B. It will likely affect those traveling in snowy conditions.
C. To prevent snow blindness on the slopes, wear sunglasses.
D. Sometimes it occurs from mail-made sources of ultraviolet radiation
E. In fact, snow can reflect over 80 percent of the UV rays that fall upon it.
F. Snow blindness is scary, but usually it's temporary, and there are ways to relieve the discomfort.
G. But water and white sand also are highly reflective of the sun's UV rays, thus increasing the risk.
I love Fridays. And so I celebrate Fridays.
After dropping my son off at school I head to Starbucks to pick up a coffee treat or another. Then instead of driving straight home I take a long route through the most beautiful roads I can find. I see footballs being passed on lawns, hamburgers being thrown on grill(烤架), and parties everywhere swinging into action.{#blank#}1{#/blank#}
The o0ther day I came out from the doctor's office happy over a positive prognosis(预断). Seeing the signs of spring around me-flowers, birds, sunshine, I was suddenly ready to celebrate. {#blank#}2{#/blank#}
My mind rebelled. “What are you doing? It's Tuesday! Coffee treats are reserved for Fridays!”{#blank#}3{#/blank#} Why should Fridays be any more special than any other day of the week? Why waste six days while waiting to celebrate the seventh? Minutes later I was walking back to my car with a big smile on my face and a coffee in my hand.
A small victory, to be sure, but it's also an accurate example of how many of us live our lives. We're waiting for conditions to be right before we allow ourselves to enjoy our time here on earth. Maybe when we finally graduate from college and get a job, it will be time to celebrate, or perhaps when our babies are old enough to be in school all day. We'll celebrate when the car is paid off, or enjoy life when we're finally able to retire. {#blank#}4{#/blank#} What if we moved a little of that “Friday feeling” into our rainy-day Mondays, our dull Tuesday and our mid-week Wednesdays? {#blank#}5{#/blank#}
A. You must spend more time achieving it. B. Surely our lives would be much happier as a result. C. It seems as if the whole world is celebrating Friday! D. But suddenly I realize how ridiculous that line of thinking was! E. Find an excuse to celebrate and start sending out hose invitations. F. I headed for the coffee bar that was located just around the corner. G. And in that waiting we waste so much of life and happiness that can be found in our Todays. |
