Virtual live facilitator-led courses give you comprehensive training right from your own computer. Virtual Live Classroom (VLC) training provides hands-on learning, interactivity and participant engagement, all with the flexibility of learning from wherever you choose. Practical components are demonstrated whereafter the student completes the training requirements by gaining the necessary practical experience at a face-to-face practical training day that occurs on site in Cape Town, Johannesburg, Durban, George, Port Elizabeth, Nelspruit, Windhoek and Harare.

| Term | Definition |
| Accommodation | The process to keep the focus point on the fovea by adjusting the lens. |
| Binocular vision | Using or testing two eyes simultaneously, also the to fuse the two images into a single image. |
| Blind spot | Sightless area within the visual field of a normal eye. The area where the optic nerve enters the eye where there are no light sensitive photoreceptors. |
| Colour deficiency or colour blindness | Reduced ability to distinguish between colours, most commonly red and green. Usually, inherited, it is caused by a shortage or lack of certain photoreceptors (cones). Although there is no cure, this condition does not significantly impact most day-to-day vision functions. |
| Colour vision | Ability to perceive differences in colour, including hue, saturation, and brightness. |
| Convergence | Inward movement of eyes toward each other, usually to maintain focus on closer objects. |
| Depth perception | Stereopsis - is how a person judges how far away an object is from him/her, combining such factors as the apparent size of the object, its apparent rate of motion, the object's height in the field of vision, the image's clarity, and various shadows. |
| Diplopia | "Double vision," when a person sees two images of an object instead of one, the images may be horizontal, vertical, or diagonal. double vision in only one eye - Monocular diplopia - can be caused by factors including astigmatism, dry eye, and retinal problems. double vision in both eyes - Binocular diplopia -– is caused by a misalignment of the eyes and is often treated with vision therapy. |
| Informed Consent Form | Document disclosing the risks, benefits, and alternatives to a procedure. |
| Ishihara test | A test that screens individuals for colour deficiency / colour blindness. |
| Lacrimal apparatus | The system producing and distributing tears to lubricate the eye. |
| Legal blindness | Best corrected visual acuity of 20/200 or less. |
| Monocular | Pertaining to one eye. |
| Muscle Balance | The ability of the eyes to remain in one position. |
| Muscle Imbalance | The tendency of either eye to turn away from the position of fixation when fusion of images is prevented; esophoria or exophora. |
| Near point of accommodation | Closest point in front of the eyes that an object may be clearly focused. |
| Near point of convergence | Maximum extent the two eyes can be turned inwards. |
| Ophthalmologist | Specialist physician for diagnosis and treatment of all refractive, medical, and surgical problems related to eyes, eye diseases and disorders |
| Optician | Designs, verifies, and dispenses lenses, frames and other fabricated optical devices upon the prescription of an ophthalmologist or an optometrist. |
| Optometrist | Eye care professional, graduate of optometry school, provides non-surgical visual care. Specifically educated and trained to examine the eyes and determine visual acuity as well as other vision problems and ocular abnormalities. An optometrist prescribes glasses and contact lenses to improve visual acuity. |
| Orthoptics | Discipline dealing with diagnosis and treatment of defective eye coordination, binocular vision and functional amblyopia by non-medical and non-surgical means such as glasses, prisms, exercises. |
| Phoria, Lateral | Indicates the accommodative-convergence relationship and if there is a lack of coordination between the eyes |
| Phoria, Vertical | Description of the relative, vertical position assumed by the eye when dissociated. When the tendency is for the right eye to turn upward; the condition is known as right hyperphoria. When the left eye tends to turn up, the condition is left hyperphoria. |
| Refraction | Bending of light waves as the wave move into a different medium, the cornea and lens refracts light to fall directly onto the retina. |
| Suppression | Inability to perceive all or part of objects in the field of vision of one eye. |
