Eyesight is a valued sense that provides us a window through which we can see the world. Most people fear the loss of vision more than any other form of disability. When a person loses sight, he is not able to participate in many activities of ordinary life. The family of the affected person undergoes significant costs of taking care of the individual. Eye health, therefore, concerns everyone, and we should make every effort to prevent avoidable eye loss and improve eye health.
One of the practices aimed at improving eye health is getting regular eye exams. An eye exam is necessary to everyone, regardless of whether or not you have ever experienced eye problems. There is a misconception about eye check-ups or eye exams – that one should go for an eye exam when they experience an eye problem. If you live in Toronto, there are many optometrists downtown Toronto for your convenience and optimal eye health.
When should you start going for eye exams?
It is recommended that you have a comprehensive eye exam every two years if you are over 20 years of age. The exam helps to ensure that your vision remains sharp, and your eyes stay healthy. If you use contact lenses or have a medical condition such as diabetes, eye trauma or surgery, or a family history of glaucoma, you need to have more frequent eye exams. Children too need to go for visual screening once a year after they start going to school. After the age of 65, one needs to have a comprehensive eye exam once a year to rule out eye complications.
How long do eye exams take?
The time taken depends on whether or not it is your first time to visit an eye doctor. It may take around one hour to have a complete eye exam. Regular check-ups do not take this much time.
What is done during an eye exam?
Your downtown Toronto optometrist will ask you to tell of any vision or eye problems and how long you have experienced them. The eye doctor may also require information about your overall health and any medication you are taking. Many eye doctors also seek to know their patient’s family’s medical history.
The following tests are carried out:
1. Visual acuity test: Is a test that checks your vision with a Snellen chart. You will be asked to read random letters and numbers that become smaller line after line as you move down the chart.
2. Keratometry: Is a test that helps to measure the curvature of the cornea. The optometrist focuses light on the cornea and measures its reflection. Keratometry helps the doctor to determine the proper fit for contact lenses.
3. Slit-Lamp Examination: This exam evaluates your eye health. It detects signs of infection or disease. You will be asked to place your chin on the chin rest of a spit lamp. The doctor will shine the lamp’s light at each eye and examine each part of the eye.
The optometrist may perform other tests to check other aspects of your vision. These tests include visual field test (to check your peripheral vision), stereopsis, ophthalmoscopy, and retinal examination.
