A full eye examination can include specialised eye testing to check the vision and the overall health of the eye.
These tests may include testing and, if necessary, the measurement of:
- Visual acuity (Snellen eye chart)
- Vision (refraction test)
- Eye alignment (single cover test)
- Examination of the front of the eye
- Manual refraction (phoropter)
- Eye pressure (glaucoma test)
- Retinal examination (digital retinal scan)
Eye conditions detected and corrected by eye examinations include the following:
Also referred to as near-sightedness or myopia, this is the most common problem in the eye. Light does not focus properly on the retina, instead it converges slightly in front of it, causing blurred distance vision.
Short-sighted people can often see reasonably well at short distances but cannot focus on objects that are far away.
Longsightedness, or Hyperopia, happens when the optical components of the eye are not strong enough to focus the light onto the retina, causing blurred vision.
Long-sighted people usually have good distance vision but will find that their vision is blurred at short distances.
Also called lazy eye, this occurs when the vision in one eye is reduced because the eye and the brain are not co-ordinating correctly. Often detected in children, this condition can be treated by a variety of methods to balance the brain back to using both eyes equally.
This is a normal condition of ageing where the eye becomes unable to focus by as much as it used to, usually happening over the age of 40.
Most people of this age will find that they cannot focus clearly on near objects any more and will require visual correction for close work.
This condition arises when the optical power of the eye varies depending on the angle of light passing through it, causing refractive error.
This leads to blurred vision at all distances, with varied focus over the range of view.
Diplopia, commonly known as double vision, can have several causes. It happens when the eyes fail to work together to generate a single vision image. It needs to be investigated incase it is a symptom of underlying eye disease or condition.
Children’s vision and school achievement
Visual problems can interfere with a child’s school work and parents should look for signs such as squinting, headaches, rubbing of the eyes and holding a book too close or too far away when reading.
Since visual skills are critical to learning and reading, it is vital that eye tracking is checked as well as general vision.
Insight Optometrists recommends annual Eye Checkups.
