What is the role of an Optician?

Eye disorders result from various problems involving any part of the eye. Optometrists offer crucial vision care that includes vision testing and rectification, diagnosis, treatment, and administration of vision alterations. Optometrists generally carry out eye exams and eyesight tests, recommending and allotting corrective lenses, identifying eye diseases, and advising on the required medications for specific eye illnesses.

The most common and known eye care experts are opticians. Very few people understand the tasks assigned to an optician. Opticians are skilled in designing, validating, and fitting eyeglass lenses, frames, and contact lenses to correct vision. Opticians apply treatments given by optometrists. They do not typically test vision or provide prescriptions. By visiting an optician near you, you will get the right design and lenses that fit the correction of your eyes.

How Opticians Help You Choose & Fit Contact Lenses?

Contact lenses are positioned right on the external of the eyes and are used to rectify vision. In choosing the contact lenses, an optician or optometrist will consider various factors: different types of lenses, prescription, shape, features, and perfect fit:

Choosing Correct Lens from Different Types of Lenses

Contact lenses are different according to their main functions, material, wear, and replacement schedule. Correction of refractive error contact lenses, presbyopia contact lenses, cosmetic contact lenses, therapeutic scleral lenses, and therapeutic soft lenses differ according to their primary functions. Rigid, soft, and hybrid lenses are according to their material.

The wear schedule is for a given period. The daily wear contact lens is to be put on for one day and removed while sleeping while the extended wear contact lens is approved to be worn overnight. Depending on the replacement schedule, the contacts should be replaced daily, biweekly, or monthly.

Understanding the Prescription by an Optometrist

Prescription affects the contact lens shape and thickness. An eye exam determines the suitable contact lens wear for an individual. An optician has to consider the prescription given before choosing a contact lens.

Choosing the Right Lens Shape

The correction your vision needs leads to the precise shape of contact lenses. Lenses have spherical and toric designs.

Helps to Perfect Fit Contact Lenses

The contact lenses you choose should align with your pupil. Your eye care provider needs to ensure that the lenses are not too loose or too tight on the eyes.

Helps with Lens Fitting

The optician takes some measurements to correctly fit your contact lenses in fitting the lens since contact lenses are of different sizes. The measurements required by your optician for contact lens fitting include:

  • Corneal curvature – the measurement of the corneal curvature assures that the fit curve of the lens correctly fits the curve of your eye. Keratometer is used to determine the suitable curve for your contact lenses.

  • Pupil size – biomicroscope measures the size of your pupil

  • Tear film evaluation – Eye doctors ensure adequate tear film to keep the lenses moist and contented.

After deciding on a suitable pair of lenses, the optician inserts the lenses and keeps them in for at least fifteen minutes before the optometrist examines the fit, movement, and tearing in your eye. The optician provides care and hygiene instructions. You learn how to insert and take out the lenses, safely clean them, and the proper replacement schedule to wear them.

Benefits of Wearing Contact Lenses

  • Contact Lenses give excellent sight correction.
  • Contacts eradicate the necessity to wear eyeglasses all the time.
