Home eye tests offer a practical way to monitor vision changes when professional services are inaccessible. These tests, while not a replacement for comprehensive exams, provide preliminary insights into eye health. From conducting simple tests at home to utilizing online screenings, understanding these methods empowers individuals to take proactive steps in maintaining their vision health.
Understanding Home Eye Tests
Home eye tests have become a practical solution for individuals looking to monitor their eyesight without visiting an eye care professional. These tests are particularly useful during times when access to professional services is limited, such as during the coronavirus pandemic (source). While home tests can provide a preliminary assessment of vision changes, they are not a substitute for comprehensive eye exams conducted by ophthalmologists, which are essential for detecting underlying health issues early (source).
Conducting a Home Vision Test
To perform a home vision test, certain supplies are necessary, including a printed eye chart, a well-lit room, and basic items like a paper cup or tissue to cover the eye, scissors, tape, a pen, a yardstick, and a flashlight. The setup involves placing a chair 10 feet from a wall where the chart is hung at eye level (source). For children, a “pointing game” using a practice E card can be employed, while adults and older children should read the letters aloud with one eye covered. The smallest line read correctly should be recorded for each eye (source).
Types of Home Vision Tests
Several types of home vision tests are available, including the Amsler grid, distance vision, and near vision tests. The Amsler grid is particularly useful for detecting macular degeneration by identifying distorted or missing lines on a grid (source). Distance vision tests involve reading an eye chart from 10 feet away, which can indicate issues like nearsightedness or astigmatism if the 20/20 line is not read correctly. Near vision tests are similar but conducted with the chart held 14 inches away, helping to identify issues like presbyopia (source).
Online Vision Screening
Online vision screenings, such as those offered by ZEISS, provide a convenient way to check eyesight from home. These screenings include tests for visual acuity, contrast vision, color vision, and astigmatism, simulating traditional eye tests to give users an initial impression of their vision quality (source). While these screenings can offer useful insights, they are not a replacement for professional eye care and should be used to determine if a comprehensive eye exam is necessary (source).
When to Seek Professional Help
Abnormal results from home vision tests suggest the need for a professional eye examination to diagnose potential vision problems or eye diseases. Symptoms such as difficulty focusing, double vision, or blurred vision warrant a professional eye examination, as do specific symptoms in children like crossed eyes or excessive blinking (source). Recording the results of a home vision exam can be useful for an ophthalmologist if further examination is needed (source).
