Sight Testing vs Comprehensive Exams

In Canada a number of optical stores offer sight tests performed by a computer. This particular test is rarely performed by a qualified optometrist. A doctor of optometry can examine, diagnose, treat and prevent certain eye diseases. An eye exam by a doctor includes a case history, and analysis of a patient’s visual needs, and a determination the right treatment. The accuracy of the automatic machines is limited, and will not detect and underlying conditions, such as the onset of glaucoma, early stages of diabetes, retinal detachment, high blood pressure, or certain brain and eye tumours.

The doctor checks for refractic errors such as Hyperopia (far sightedness), myopia (near sightedness), presbyopia, astigmatism and many other eye conditions.

What is a high index lens?

A high index minimizes the thickness of a lens, so that they are more lightweight and cosmetically appealing, by reducing the ‘bug eye’ look, while still providing great optical quality.

How good are the inexpensive over-the-counter (OTC) reading glasses?

If you do not require prescription reading glasses, your eye doctor will let you know, but otherwise it is highly recommended that proper prescription glasses are used. Some of the reasons are

  1. Power in OTC readers are the same in both eyes, but your prescription may be different in each eye, therefore looking through OTC readers will make one eye work much harder than the other and will cause eye strain, discomfort and headaches.
  2. OTC readers will not correct astigmatism..prescription readers will.
  3. Custom made prescription glasses are made so that the centre of the pupil and the optical centre of the lens are lined up to give you a perfect vision.
  4. Prescription lenses are made without distortions, OTC’s of low quality may have defects such as waves or bubbles.

What is an anti-scratch or scratch resistant lens?

Lenses that treated with an anti-scratch coating have a much harder surface that is more resistant to scratching. No anti-scratch coated lenses are completely scratch proof and normal wear and tear will develop some scratches.

When driving at night, especially in rain, my eyes are bothered by glare. What can be done?

To reduce or eliminate glare, use anti-reflective coating on your lenses. Anti-reflective coated lenses decrease halos around light, help you see without staring and also improve your appearance by reducing light reflections on your lenses.

Do I need an eye exam to wear contact lenses?

Yes. You must be examined by an eye doctor. Measurements of the eye and overall eye health must be determined to prescribe and evaluate your vision, fit, comfort and type of contacts.

What are Progressive lenses?

Progressive lenses also known as no-line bifocals, are multi-focal lenses that offer clear vision for distance, mid and near vision but without lines.

Can I use my eyeglass prescription to purchase contact lenses?

A contact lens prescription is different from your eyeglass prescription, but our doctor and qualified staff can use the information to convert to correct contact lens prescription.

What is Refractive Error?

Refractive error occurs when the eye doe not bend light as it enters the eye, resulting in a blurred image. Most commons Refractive errors are:
  1. MYOPIA or Nearsightedness is a condition in which nearby objects are seen clearly, but distant objects are blurred. Can be corrected with eyeglasses, contact lenses or corrective surgery.
  2. HYPEROPIA or Farsightedness is a condition in which distant objects are seen clearly, but nearby objects are blurred. Can be corrected with eyeglasses, contacts or corrective surgery.
  3. ASTIGMATISM occurs when the cornea has an irregular curvature, when it is curved more in one direction thus causing blurry vision. Astigmatism can be corrected with eyeglasses, contacts or corrective surgery.
  4. PRESBYOPIA occurs around the age of 40. It is a normal aging process of the lens of the eye, causing difficulty focusing at close range and can be corrected with eyeglasses and contacts.

What foods are good for eye health?

Studies show that people who eat vegetables such as spinach, kale, collards, dark green lettuce, carrots, omega 3 essentials and flax seed oil, are at a lower risk of developing certain eye diseases and conditions. Eat those greens!
