Benefits of Eye Exams

Healthy vision is a necessity for success in many areas of life. Children depend on accurate vision for learning, activities and sports. Daily elemental aggressors from digital device over use, environmental exposure and lifestyle can compromise eye health. You will gain beneficial information during your eye exam to help maintain healthy vision and detect eye disease.

At 20/20 Eyecare of London, we utilize the latest technology to provide both routine and medical eye care. Our eye care specialist will examine all aspects of eye health, externally and internally down to the optic nerves in a comprehensive eye exam. Your eyes are also a portal to internal physiological conditions. Eye exams can offer advanced detection of health issues. Some eye conditions can occur without symptoms or sensation, causing progressed issues over time if not detected early.

Basic Comprehensive Eye Exam Tests

Visual Acuity (Sharpness of vision)
Your vision sharpness is measured using an eye chart for distance acuity and a smaller manually held acuity chart for near vision.
Glaucoma Test (Measures internal eye pressure)
A non-painful “air puff test.” A light puff of air is projected onto the eye to determine eye pressure.
Color Blindness (Screening to check color vision)
An Ishihara color chart measures your ability to differentiate colors. Our eye care expert can also detect hereditary color vision deficiencies and potential health issues affecting color vision.
Cover Test (Eye alignment)
Focus on a targeted object at a distance and close-up while covering alternate eyes.
Ocular Motility (Eye movement)
Testing for eye movement accuracy at varied speeds and fixation on separate targets.
Stereopsis Test (Depth perception)
3D glasses are worn for viewing circular test patterns to identify closer or distant circles.
Retinoscopy (Eyeglasses prescription and cataract test)
A small beam of bright light is projected into the eye to detect cataracts, or cornea distortion. Eyeglass prescription is determined by light reflection shifts as our eye care expert changes powered lenses placed in front of the eyes.
Refraction (Eyeglass prescription and presence of farsightedness, nearsightedness, or astigmatism)
A small instrument featuring various lens prescriptions is placed in front of the eyes. You will select which lens power offers the clearest vision. Refraction testing also determines “hyperopia” (farsightedness), “myopia” (nearsightedness), and “astigmatism,” a refractive error resulting from cornea irregularities.
Visual Field Test (Checks for blind spots or peripheral vision issues)
Focus on a target with one eye covered and additional objects introduced in your peripheral. Certain blind spots can be a precursor to glaucoma or indicate damage to the brain resulting from stroke or tumor.

What Can I Expect During an Eye Exam?

Anticipate an hour to an hour and a half for your appointment from start to finish. Once you have completed your initial eye exam, our specialist may schedule a diagnostic follow-up examination if any issues are discovered. Additionally, you may need to return to the office to pick up your glasses, which can take extra processing time.

When planning consistent medical appointments, it is recommended to always include an eye exam! One annual eye exam can bring beneficial and preventative results for you and your family. Sensational vision supports a thriving life, improved learning skills, resilience to environmental stressors and confidence in complete health. We strive to provide our services in a comfortable and friendly environment for patients of all ages. We look forward to serving you!
