Prescription glasses for presbyopia
If you wore glasses before you started noticing the effects of presbyopia and you want to keep wearing glasses, prescription glasses for presbyopia could be a good fit for you. They might also be prescribed to you if over-the-counter glasses aren’t correcting your close-up vision well enough. Here are a few of the most common prescription glasses options
Prescription reading glasses
These are exactly as they sound—reading glasses that your Optician must prescribe to you. You may need these if, for example, both your eyes are not the same prescription or if you have uncorrected astigmatism. Prescription reading glasses should only be used when you’re reading, as they only correct near vision and will not correct your other vision issues.
Bifocals
An invention widely credited to Benjamin Franklin, bifocals correct close-up and far vision by using two different lens powers in the same pair of glasses. The bottom of the lens corrects presbyopia, while the top can incorporate your current prescription for distance vision. The two powers are divided by a line (which may or may not be visible).
Trifocals
These use the same idea as bifocals but add an extra area to correct for mid-range vision, so you have three areas of vision correction with three different lens prescriptions. Trifocals work best for people who need their vision corrected whether they’re looking at something close up, far away, or in between. But note, since they have different powers depending on where you look, they do take some getting used to.
Varifocal lenses
These glasses work similarly to bifocals and trifocals, but instead of having a distinct division between the different powers of the lenses, the vision correction gradually changes in the lens from top to bottom.
