I want to try DISPOSABLE contacts.
I have been wearing glasses since I was 4, daily wear contacts since I was 12
(I’m a 34 year old female) with severe nearsightedness at:
Left Eye: BC: 8.3 - DIA: 13.8 - POWER: -8.00
Right Eye: BC: 8.3 - DIA: 13.8 - POWER: -8.50

I have only been able to find my base curve and diameter in daily wear
contacts. But now I have seen online that there are disposable contacts now
at BC: 8.3 and DIA: 14.0 in my power strength. Question is the diameter
increase from 13.8 to 14.0 significant enough to be uncomfortable or is it so
close a fit I won’t notice the difference? How relevant are diameters in
fitting when dealing with numbers that close? Thanks

You do need to get a valid prescription from an eye care provider.
The change in diameter should be neglible.

Generally speaking, because you definitely need a written prescription
from your eyecare provider, 8.3/13.8 (BC/Diam) is roughly equivalent to
8.6/14.0. This will, however, change depending on the available lenses
you will be receiving. Some of the new silicon hydrogel lenses are
designed to be fit tighter. This is why your doctor needs to make the
assessment.
