Hectic schedules often make it difficult to take time out to focus on our eyes. Regardless, it is important to remember to have yearly eye exams to ensure proper eye health. Only a comprehensive eye exam can truly determine optimal eye health an ensure visual acuity.
The following will help you to better understand the meaning of each test performed during your eye exam.
Measures your eyes’ ability to see details at near and far distances. These measurements are performed using the Snellen chart: the last line that can be read easily indicates your level of visual acuity.
Measures refractive error, an optical condition in which the eye fails to bring light into sharp focus on the retina, resulting in blurred or distorted vision. It determines refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism and/or presbyopia.
Measures the curvature of the cornea. The keratometer is used to fit contact lenses. For eye safety and comfort, contact lenses must follow the curvature of the eye. This instrument also diagnoses certain corneal diseases.
Evaluates the ability for both eyes to work together. Adequate muscle balance is required in order to see three-dimensional shapes.
