We use our Vision to perceive information about the world. Reading and writing require being able to see the detailed features of text clearly and being able to track text on paper and a website. Students with uncorrected Vision issues can have difficulty distinguishing letters and reading and writing at the same rate as peers with normal or corrected Vision.
Several different Vision components and skills are important in learning to read and write:
Early identification of Vision problems is critical for preventing academic difficulties later. Some behaviors that can indicate a student has uncorrected Vision issues are covering or closing one eye, rubbing their eyes frequently, complaining of double vision, losing their place while reading or writing, or experiencing Attention difficulties.
Vision screenings at school typically only assess visual acuity, so it is possible for a student to have a Vision problem in other areas even though they pass the screening. So if a student is at risk for having Vision problems, they should receive an extensive eye examination regardless of screening results.
