PRESCRIPTIONS

WHAT ARE PRESCRIPTIONS?
━━━

Prescriptions refer to written authorizations for a patient to purchase medications to treat specific conditions. For a prescription to be legally accepted, it needs to be written by an authorized physician, dentist, psychiatrist, ophthalmologist, optometrist, and any other doctors officially recognized by law.

Every medical profession has its own rules and limits with what kind of prescriptions they can provide.

PRESCRIPTIONS IN OPTOMETRY
━━━

Optometrists are state-licensed medical professionals who specialize in eye health. Optometrists examine, diagnose, and treat various eye conditions such as diseases, injuries, and disorders. They can prescribe eyeglasses and contact lenses when necessary. For example, they are the ones who diagnose refractive errors (nearsightedness, farsightedness, presbyopia, astigmatism etc.) and prescribe corrective contact lenses and eyeglasses. 

They are also authorized to prescribe ophthalmic drops to treat conditions such as glaucoma.

THE OPTICIANS’ ROLE
━━━

Once your optometrist has written your prescription, the opticians manage what happens next. Opticians work in a lab and use manufacturing machines to cut lenses based on optometrists’ prescriptions. At Eyepic, we use the most advanced technology and best lens brands to ensure that all our patients receive the best eyeglasses possible. Using the best optical machines ensure quality control over the final product and allow us to achieve superior vision care.

Cylinder – This represents the lens power that will be needed to correct astigmatism

Axis – The axis is the orientation of astigmatism. It is measured from 1 to 180.

Prism – The prism number indicates the prismatic power needed to compensate for any alignment problems in your eyes. It is measured in diopters.
