Background and Objective: It is well accepted that accommodation system is characterized by steady state error in focus. Usually near addition lenses are prescribed to prepresbyopic individual for treatment of binocular motor problems such as convergence excess and accommodative disorder. The purpose of this study was to evaluate the near addition lenses in accommodative and vergence responses at three viewing distances. Materials and Methods: This semi-experimental study was done on 42 students of 17-25 years old in Zahedan, South-Eastern Iran during 2009. After correction of refractive error, phoria states with APCT and binocular and monocular lag of accommodation by MEM method with and without +2.00 lenses in three difference distances (30, 40, 50 cm) was measured. Data analyzed by ANOVA, t-student and paired t-tests. Results: There was significant difference between average of lag of accommodation and phoria at various distances, with and without lens (P<0.05). Also, there was significant difference between mean of lag in 3 fixation distance (P<0.017). There was no significant difference between average of lag of accommodation and phoria at various distances in three group of refractive error. Conclusion: Our results showed that, near addition lens reduce the lag of accommodation. It is proposed, therefore, according to near emmetropization theory addition lenses may be effective in reducing of the myopia progression.

Background and Objective: Childhood behavioral and emotional problems may be continus to puberty, even extend to elderly. This study was carried out to determine the role of family accommodation of child symptoms, parenting style and parental stress in prediction of anxiety disorder in children with 6 - 10 years old in Golestan province, north of Iran.

Methods: In this descriptive-analytic study 300 children with 6-10 years old and their mothers were selected by randomized cluster sampling method during 2017. The questionnaires of family accommodation scale-anxiety (FAS-A, 2013), parent stress index-sort form (PSI-SF, 2000), Bamerind parenting styles questionnaire 1973 and Spence child anxiety scale-parent form (SCAS-P, 1998) were completed by the mothers.

Results: Increasing family accommodation and parenting stress significantly correlated with increasing children anxiety (P<0.05). The authenticated childbearing style by parents significantly correlated with reducing the anxiety in children (P<0.05), but authoritarian parenting and permissive parenting by parents significantly correlated with increasing the anxiety in children (P<0.05). Authenticated childbearing style along with authoritative parenting style, parental stress and family support could predict 49% of children's anxiety (F=97.91, P<0.0001).

Conclusion: Authoritative and authoritarian parenting, parenting stress, family accommodation has an effective role in predicting children's anxiety.
