Purpose: To find out the color vision defects among textile mill workers in Lahore. Study Design: Descriptive cross sectional study. Place and Duration of Study: University of Lahore from June 2019 to December 2019. Methods: Study was done at different textile mills in Lahore, Pakistan. Self-designed proforma was used to record data including age, gender, occupation, any medication or surgery. The workers with best corrected visual acuity of 6/6 and refractive error less than 3.00 D of sphere or astigmatism less than 1 D of cylinder with no history of ocular surgeries were included in the study. Color vision was assessed using Ishihara Isochromatic color plates. Examination of the anterior segment and posterior segment was done by using slit lamp Biomicroscopy and 90 D of condensing lens.Data was entered and analyzed using the SPSS version 22. Results: During this study 1,250 textile mill workers fulfilled the inclusion criteria. Six hundred fifty were males and 600 were females. Only 10 workers were suffering from color vision deficiency, which was 0.8% of the total sample size. All of the color vision deficiency patients were male of different age group. Conclusion: It has been concluded that although textile industry is based on colors, there is no proper color vision examination in our textile sector. Colour vision deficiency awareness should be increased so that everyone in the community is well aware of it. The test of color vision must be made compulsory in pre-employment examination at public and private sector at every Level.

<p><br />Buta warna adalah ketidakmampuan seseorang untuk membedakan beberapa warna yang dapat dibedakan oleh orang lain. Penyakit ini disebabkan oleh mutasi pada gen OPN1LW, OPN1MW, dan OPN1SW. Keadaan ini diturunkan dengan pola X-linked atau bisa juga didapat setelah lahir. Tujuan penelitian ini adalah untuk menentukan prevalensi buta warna pada mahasiswa Universitas Muhammadiyah Palembang. Penelitian ini merupakan penelitian deskriptif observasional dengan desain potong lintang yang menggunakan data sekunder. Besar sampel sebanyak 174 orang diambil dengan metode stratified random sampling di Fakultas Ekonomi, Fakultas Hukum, dan Fakultas Agama Islam. Mahasiswa yang dipilih adalah mahasiswa angkatan 2017 yang namanya terdaftar di www.forlap.dikti.go.id. Data status penglihatan warna diambil dari arsip skrining buta warna milik Klinik Dokter Keluarga Fakultas Kedokteran UM Palembang. Skrining buta warna dilakukan tim kesehatan penerimaan mahasiswa baru, yang terdiri dari 7 dokter umum, dengan menggunakan Buku Ishihara sebagai alat bantu. Sampel terdiri dari 88 orang laki-laki (50,6%) dan 86 orang perempuan (49,4%). Penelitian ini hanya menemukan 1 subjek penelitian dengan buta warna (0,6%) berjenis kelamin laki-laki. Angka ini lebih rendah dari angka kejadian nasional yaitu 0,7% dan angka kejadian di Sumatera Selatan 12,8%. Hasil penelitian ini sesuai dengan teori bahwa biasanya buta warna terjadi pada laki-laki karena memperoleh kromosom X dari ibu yang membawa alel buta warna. Kesimpulan, prevalensi buta warna pada mahasiswa Universitas Muhammadiyah Palembang tergolong rendah bila dibandingkan prevalensi nasional.</p>
