This caught my eye:
How temporarily, you might wonder, as I did. Very temporarily, it turns out:
Kedar told Forbes that the drops, which are made out of chemicals that are already found in common eye medications, were shown to immediately reverse farsightedness for a number of hours.
Wow, a number of hours. The article also says:
“CSF-1 can potentially alleviate the burden of reading glasses and offer a meaningful solution for billions of people living with age-related farsightedness worldwide.”
Speaking as someone who just got reading glasses less than a year ago, and is not thrilled about it … I cannot imagine voluntarily putting eyedrops into my eyes multiple times a day, when I could just pick up reading glasses multiple times a day.
Obvious problems with the eyedrops:
–You can take off reading glasses at a moment’s notice. Once the eyedrops are in, you are stuck with their effects for hours.
–You have to, I guess, carry them with you, as the effect is so temporary.
–You have to put them in your eyes.
Now, I fully realize that some people put eyedrops into their eyes all the time. But I could hardly tolerate eyedrops that one day last winter when I was at the ophthalmologist’s, having my eyes checked.
It seems to me we already have a meaningful solution for billions of people — that is probably an overstatement, since I assume that not every single person over fifty needs reading glasses — but anyway we have a solution for people living with age-related farsightedness. This solution is called “reading glasses.”
Get back to me when you have eyedrops that offer a permanent fix for age-related farsightedness. Until then, no thanks.
