Trifocals: Wishing for 3 Eyes
I finally understand why [some] people arrive at the unfortunate point where trifocal eye wear becomes a necessity. Trifocals provide three distinct focal lengths to allow for accurate navigation through daily routines involving close up paper work, mid-range computer work and far off distance vision.
Once upon a time I had eyes that managed to maneuver between all three ranges perfectly (sigh) but somewhere in my mid to late 30's (yes, it started early for me) I noticed the dreaded blurring of objects close to my field of vision. Reading glasses were the short term solution but after going through oodles of pairs and constantly losing them (on/off/on/off), I went for a contact lens, in just one eye. One eye for close up vision, one eye for distance vision; it was great while it lasted. Gradually though, I began to need stronger and stronger magnification on my close up eye and then my distance eye started getting blurry. Yikes! So, for awhile it was a lens in each eye, just different strengths; still one eye for up close and one for distance. And that worked for another few years.
Finally the dry eyes and relentless escalation in need for more powerful lenses necessitated a switch to glasses. So, out with the contacts and in with the eye wear! At least with progressive lenses, bifocals no longer sport those dreaded lines. I've been quite happy with my glasses for the last two years until.......
I started noticing ever so slowly (isn't it always this way?) the mid range vision used for desk top computer work becoming fuzzy around the edges. Suddenly my neck was in a spasm of flexion as I strained to focus on the screen through the lower half of my glasses. Do this day after day and it becomes clear that bifocals alone are not going to cut it. Trifocals? Really?
If I had 3 eyes, I could get a 2.5 power for my reading eye, a 2.0 for my computer eye and a 1.5 for my driving eye. Sweet.
In the meantime, I stick with my progressive bifocals and use my cutsie pair of leopard print 2.5's for my as needed computer use. Oh, and I use my 1.5 sunglasses for the highway (I literally have to wear readers to drive). On/Off/On/Off. Here. We. Go. Again.
To those of you who've had to deal with myopia and corrective lenses/contacts all your lives, I know I'm whining about small potatoes. Forgive me. For those of you who've enjoyed pristine vision all your life....it's coming. And for those who have had good vision and are now in my boat, I know you get it. It bites.
