Why can you get farsighted glasses (+ prescriptions) off a rack at the dollar store but near sighted glass (- prescriptions) need an optometrist appointment
In: 11
Around the age of 35, humans’ eye muscles responsible for focusing on near objects deteriorate, so even those born with/live with/got lasik to 20/20 vision will need reading glasses eventually. There doesn’t seem to be an equivalent phenomenon in eye muscles focusing on distant objects.
A new medicine in the form of eye drops has changed this, however, giving many of us over-35s an ability some of us haven’t enjoyed for decades.
