Inside the eye, there is a lens, which changes shape when we look at near distance. This lens is very flexible at birth. Over time this becomes less flexible. This is when reading glasses help to make up for the loss of clarity for in near vision. This is known as Presbyopia.
If you have Presbyopia, you will have a number next to 'ADD' on your prescription supplied to you by your Optometrist. An Intermediate ADD is given sometimes if you need glasses for a specific working distance. If you are unsure as to which 'ADD' to enter in the prescription form, then, take a photo of your prescription and email it to us on email@example.com or firstname.lastname@example.org
The Optometrist will then contact you to confirm your prescription.
If you have a distance and reading correction, then you can either go for two separate pairs of single vision lenses or varifocals.
