DEAR ABBY: The letters that have appeared in your column about safe driving prompt this one. I hope you will consider my experience worth sharing.
I have poor depth perception. I make adjustments for this problem and check the distance between me and the car in front of me by looking at the distance on the road and not at the car.
I began to notice that the cars coming at me were "fuzzy" and that I had to close one eye to have a clear image of them. Then I realized I was doing the same thing while watching television. I mentioned it to my optometrist, and she checked my eyes and found that I had double vision. The adjustment to my prescription was so slight that you would not notice it, but I can now see clearly with my new glasses. -- CLEARLY FOCUSED IN MINNESOTA
DEAR CLEARLY FOCUSED: Your letter was an eye-opener. Thank you for giving me the opportunity to remind readers to have their vision checked every year -- and to report any changes in vision to the doctor immediately.
