Purpose: to determine the characteristics of eyesight in frst-year pupils. Material and Methods. Parents were initially interviewed to establish the presence and severity of symptoms of dry eye syndrome in their children. The second stage involved ophthalmologic examination which included non-contact autorefractometry on Plusoptix A09 device and checking visual acuity with and without correction. Results. Autorefractometry revealed emmetropia in the majority of cases (79.16 %), myopia was identifed in 3.34 %, accommodation disturbance — in 11.25 %, hypermetropia — in 3.75 %, astigmatism — in 2.5 %. Visual acuity test in the majority of children revealed the maximum acuity, while visual acuity of less than 0.5 was detected in 5.4 % of frst-year pupils. A survey for symptoms of dry eye syndrome showed minimal manifestations in frst-year pupils from 0 points for the majority, up to 8 points. The most frequent complaint among the respondents was hypersensitivity to light (33.75 %) and frequent eye infammation (23.3 %). Watching TV was the most frequently reported visual workload. Conclusion. The majority of frst-year pupils (78.3 %) had high visual acuity of 1.0; 3.34 % of the children had myopia; 11.25 % had accommodation disturbance.

Purpose: to evaluate the volume of accommodation in students with the help of Tonoref III (Nidek, Japan) apparatus before and after the visual load, and also to identify the correlation of the volume of accommodation with the refraction indices and papilla size. Material and Methods. We investigated 204th year students of BSMU who passed the test of accommodation and refraction on the device Tonoref III (Nidek, Japan) 10 minutes before and immediately after a lecture. Results. We identified that the accumulative response after the exercise was weakened and clinical refraction was increased. The accommodation afterthe load was decreased. By reducing the amount of accommodation revealed an increase in the diameter of a pupil. Students with less severe refractive disorders showed a stronger increase in clinical refraction after exercise than students with moderate to high degrees of myopia. Conclusion. We concluded that the load reduces the absolute volum of accommodation, and this, in turn, leads to an increase in clinical refraction, dilated pupil and reduced visual acuity. Students with emmetropia and mild myopia are particularly susceptible to the above-mentioned changes.
