Optometrist
Protect and restore vision — examining eyes, diagnosing visual disorders, prescribing corrective lenses, and detecting systemic diseases reflected in the eye.
Optometrists are primary eye care practitioners who examine eyes for visual defects and diseases, prescribe and dispense corrective lenses (spectacles and contact lenses), diagnose and manage common eye conditions, and detect systemic conditions — diabetes, hypertension, multiple sclerosis — that manifest in the eye. Optometrists differ from Ophthalmologists (medical doctors specialising in eye surgery) and Opticians (who dispense lenses but do not examine or diagnose). In Sri Lanka, the University of Peradeniya offers the BSc Optometry degree and the National Eye Hospital (Colombo) is the national centre for eye care. With an estimated 40–50% of Sri Lankans needing some form of vision correction, and diabetic retinopathy rates rising with the national diabetes epidemic, optometry is a critically important and significantly underserved profession. Internationally, optometrists are independent primary eye care practitioners with strong demand in the UK, Australia, Canada, USA, and the Gulf States — and consistently high patient satisfaction rates.
What a Optometrist does daily
- Conduct comprehensive eye examinations — visual acuity, refraction, binocular vision assessment, ocular health check
- Prescribe and manage corrective lenses — spectacles and contact lenses for myopia, hyperopia, astigmatism, presbyopia
- Diagnose and manage common eye conditions — dry eye, conjunctivitis, blepharitis, allergic eye disease
- Screen for and refer serious eye conditions — glaucoma, macular degeneration, diabetic retinopathy, cataracts
- Detect systemic diseases through the eye — diabetes, hypertension, raised intracranial pressure, thyroid disease
- Perform low vision assessment and rehabilitation — maximising vision for patients with permanent visual impairment
- Conduct pre- and post-operative assessment for cataract, LASIK, and other ophthalmic surgical procedures
- Prescribe and manage therapeutic contact lenses — orthokeratology, bandage lenses, scleral lenses
- Conduct paediatric vision screening and amblyopia management
- Work in community eye health programmes — school vision screening, diabetic retinopathy screening camps
Step-by-Step Career Roadmap
- Develop curiosity about vision and optics — how do glasses work? What is short-sightedness? How does a camera lens mimic the eye?
- Build strong Biology, Physics, and Mathematics foundations
- Understand the difference between an Optometrist (examines and prescribes), an Ophthalmologist (eye surgeon), and an Optician (dispenses lenses)
- Visit an optometry clinic or optical shop — observe what a refraction test looks like
- Learn basic optics — lenses, focal length, refraction, light — these are directly applicable to clinical optometry
- Optometry clinic visit
- Optics experiments (lenses, prisms)
- National Eye Hospital website research
- Physics Olympiad / science fair optics project
- Optometry combines biology AND physics — students who are strong in biology but very weak in physics will struggle with the refraction and optics content of the degree
