Contrast observation of the effect of frame mirror and corneal contact lens correction on the optical properties of the human eye
Objective To explore the effect of the contrast frame mirror and the corneal contact lens correction on the optical properties of the human eye.Methods120 cases of myopia patients from 2014 September to September 2015 in our hospital for vision correction were randomly divided into two groups: control group, observation group wearing frame mirror, wearing contact lens, the optical properties of the eye were compared between the two groups.ResultsThe corrected visual acuity of observation group hadno significant difference compared with the control group;no significant difference in the values of refractive foveal contrast;foveal refractive value contrast in the two groups had no statistical difference;the observation group T30 degrees for peripheral refraction was (1.00±0.21) D, N30°peripheralrefraction was (0.34±0.08) D,were significantly lower than the control group (P<0.05).The good rate of observation group was significantly higher than the control group, the incidence of corneal complications was significantly lower than that of the control group (P<0.05).ConclusionThe frame and the corneal contact lens can be well corrected visual acuity, the corneal contact lens for the correction of certain peripheral hyperopic defocus has advantages, can effectively reduce the peripheral hyperopic defocus, delaying myopia, and improve the comfort and safety.
