Colour Blindness

Red-green and blue-yellow colour blindness is actually more accurately known as “colour vision deficiency” because you are not actually blind.

About the information on a prescription and how to understand it

Eye prescriptions look like this

A prescription for both glasses and contact lenses must include:

  • the prescriber’s name, practice address, telephone number and signature,
  • your name,
  • the date of the eye exam, and
  • all information that a licensed dispenser needs to make your glasses or fit the contacts.

A prescription will also include the power of each lens based on your specific condition: nearsightedness (myopia), farsightedness (hyperopia), blurred vision (astigmatism), or age-related need for reading glasses (presbyopia) – and may include additional information, such as magnifying power.

Contact lens prescriptions may also include information about a specific brand, material, size, or curvature of the lens depending on what you find most comfortable or is best suited to your condition.
