Your optician will probably let you try soft disposable lenses
to see if you can adapt to contact lenses. The degree does not make
a difference to the price of the soft lenses. But if you have high
astigmatism, then will need to wear permanent hard lenses which are
harder to adapt to (more irritating to the eyes, and may not be
suitable for some). There is no disposable version bec they are
expensive to make.
How old is the TS? You could have started on contact lenses earlier
as they can help to stabilise the degree (depends on individual).
In fact, over the years, my degree has decreased gradually bec of
wearing contact lenses.
