This study was undertaken to assess tear volume and stability in contaet lens wearers. Thirty-four young subjects(mean age 23. 79±3.1 years, 8 men and 26 women) without overt oeular disease were reeruited and eategorized into two groups based on eontact lens wear(soft lens, RGP lens). Measures from both eyes were made using a Sehirmer test, phenol red thread(PRT) and tear break time(tBUT) before eontaet lens wear, and at the time of 1 week, 1month and 3 month after lens wear. For the eomplete group of subjeets, the average Sehirmer wetting length was 13.76±8.34 mm, the average PRT wetting length was 17.42±6.26 mm and the tBUT averaged 4.77±2.69 see. The intereye differenees averaged 2.62±3.54 mm for Sehirmer test, 3.91±4.12 mm for PRT and 0.80±0.62 see for tBUT. Compared with the eontrol group the Sehirmer data showed a trend to be inereased at the first week but it reeovered after 1 month of RGP lens wear. After 3 months of RGP lens wear, the PRT and tBUT data showed a trend to be deereased to 27% and 21% respeetively. In the soft lens group, all the tear measures did not show any differenees at the first week eompared with the eontrol group. But after 3 months of soft lens wear, the Sehirmer and PRT data showed a trend to be deereased to 13% and 17% respeetively. As a result, wearing eontaet lenses seems to ehange the tear volume and stability. RGP lens seems to stimulate the reflex tearing but deerease the lower meniseus tear volume and tear stability, and soft lens seems not to influenee the tear film but to deerease the reflex tearing and lower meniseus tear volume.
