If you are thinking to switch glasses with contact lenses;
the first thing you need to do is to meet your optometrist. Contact lenses
cannot be purchased with the same prescription you might have been using for
your glasses. There is some correlation between the two though. Contact lenses must fit your eyes and sit properly therefore the prescription of contact lens
contains values for base curvature & diameter which the prescription for
your spectacles lack.
Should I get an eye exam even if I need cosmetic contact
lenses?
Yes. Cosmetic contact lenses too are labelled as medical devices. If you need them only for introducing a tint to
your eyes; you might not need a typical eye exam but an eye doctor will test
your eyes to check if they are fit for wearing contact lenses.
A doctor’s prescription for both prescription & plano
contact lenses may contain contact lens specific
terms such as BC, DIA, Limbal ring, water content etc. It also contains
information on brand name & design. Sometimes optometrists suggest private
label circle lenses that can be purchased from nowhere else but them. You can
always request them to prescribe a national brand or you can yourself decide on
the brand in case you have no medical complications.
I need prescription circle contacts. What next?
Short & crisp. Meet an eye doctor & get a fresh
prescription.
Prescription for glasses is somewhat different than that of circle
contacts. It may be stronger if contact lenses are conformed on the same
values of your spectacles prescription because:
- Glasses sit on your nose at a distance of 12mm almost, whereas contact lenses directly float on your eyes.
- Glasses don’t cater to peripheral vision but contact lenses do.
- Getting a fresh prescription every time you decide a switch is of significant value because your prescription might have changed & you wouldn’t want to end up buying your contacts on a wrong prescription.
A prescription also contains an expiry date. It usually
lasts a year. Therefore, you are always suggested to keep a strict contact lens
follow up exam once every year. With a fresh prescription in hand ; you can now
freely purchase your contact lenses either online or from your doctor that is
unfortunately an expensive alternate.
