An eye exam is an assessment done by an optometrist in order to determine the condition of the eye. This is a regular check that people are always advised to undergo to prevent and treat eye problems that may cause vision impairment. The procedure normally lasts about 30-40 minutes and can sometimes go beyond, depending on the needs of the patient. The optometrist will ask a lot of questions relating to your vision, overall health, and medical history to determine if the problem is genetic.
Optometrists are highly trained eye specialists who have vast knowledge and experience to perform these exams. If the result indicates that there is a problem with your vision or eye-health, the expert will come up with a treatment plan to solve the problem or refer you to a qualified physician for treatment. This usually occurs if the problem is beyond his or her professional capacity to handle, or if the patient is not responding well to treatment. The exam is performed to detect cataract, glaucoma, macular degeneration, or diabetic retinopathy. The following take place during eye examination:
– Your doctor will ask questions to determine if you are experiencing any vision problems and your medical history assessed
– Your visual acuity will be measured
– The pressure of the eye is measured
– Optometrist assesses your front eye and inside of both eyes using several lights
– Then the doctor shares whatever results he or she comes up with and addresses all of your questions
What the examination entails
Test for visual acuity
With this test, you will be asked different alphabetical letters shown on a screen that is placed at some distance or printed on a chart (Snellen chart). This will determine how clearly you can see as each eye is tested separately to obtain accurate results.
Testing your eye muscle
This test is done to determine whether there is poor coordination, weaknesses in the muscle, or if muscle control is poor. The eye muscle controls your eye movement; therefore, the doctor will watch your eye movements when your eyes follow a moving object.
Examining refraction of light
When light waves are not focused correctly at the back of your eye, then it means you have a refractive error. Light rays are supposed to bend when they pass through the cornea and lens. If this is not possible, the doctor will prescribe corrective lenses or glasses. You can get the right Calgary glasses in the Alberta area.
The doctor uses a microscope with an intense line of light to magnify and illuminate the front of your eyes. The light is used to examine your cornea, eyelids, lens, lashes, fluid chamber between the cornea and iris, as well as the iris itself.
Aberrometers and autorefractors
These devices are used to determine the type of lenses needed in order for light to be focused on the retina. With these devices doctors spend less time examining the eye and recommending eyewear that suits your eyes.
Calgary glasses are prescribed to patients by doctors, as they are affordable and work effectively for eye problems. You can rest assured that these glasses will not damage your eye, as they are best on the results of your eye test and are meant to improve your vision.
Therefore, for the best eye exam and treatment, you should visit a qualified optometrist for early detection and treatment.
