Abstract

Purpose : To study the effect of different color filters (orange, blue, grey) and no filters on reading distance, accommodation and contrast sensitivity in adults.

Methods : 16 myopic students (mean age: 24.9 ± 1.6 years, mean spherical equivalent: OD: -3.52 ± 1.81 D, OS: -3.39 ± 1.90 D) and 15 emmetropic students (mean age: 24.5 ± 1.6 years, mean spherical equivalent: OD: 0.09 ± 0.24 D, OS: 0.07 ± 0.29 D) were recruited. All subjects wore orange, blue, grey filters and no filters in random order with full correction. Polhemus Fastrack system, Grand Seiko WAM-5500 and Quick CSF software were used to measure respectively reading distance, accommodation and contrast sensitivity in four color conditions.

Results : There were statistical differences among the accommodative microfluctuations (AMF) in four color conditions (P = 0.022). AMF with blue filter were significantly larger than those with orange filter in myopic students (P = 0.046), but no difference in emmetropic students (P > 0.05). No changes were found for reading distance, contrast sensitivity and accommodative responses in both groups (P > 0.05).

Conclusions : Color filters didn’t affect reading distance. Different color filters may influence the accommodative stability in myopic adults. The accommodative microfluctuations with blue filter were larger than with the red one, indicating that blue light may play a large role in accommodative accuracy.
