The invention discloses anti-photosensitive medicinal neutral borosilicate glass and a preparation method thereof. The anti-photosensitive medicinal neutral borosilicate glass comprises the following components in percentage by weight: 68%-72% of SiO2, 8%-12% of B2O3, 4.0%-5.5% of Al2O3, 7%-10% of Li2O + Na2O + K2O, 0.5%-2.0% of CaO, 0.5%-1.5% of BaO, 0.3%-1.0% of ZrO2, 0.1%-0.5% of F-, 0.1%-1.0% of Cl-, 0.05%-1.0% of CeO2, 2%-4.5% of TiO2, 0.5%-1.2% of Fe2O3 and 0.01%-0.5% of a reducing agent. Through the comprehensive effect of all the components and the optimized process, the prepared borosilicate glass product has low ultraviolet transmittance and high visible light transmittance, degradation of photosensitive drugs is reduced, the shelf life is prolonged, and the borosilicate glass product has high practical value. 本发明公开一种抗光敏药用中性硼硅玻璃及其制备方法，其成分重量百分比为：SiO268-72％、B2O38-12％、Al2O34.0-5.5％、Li2O+Na2O+K2O 7-10％、CaO 0.5-2.0％、BaO 0.5-1.5％、ZrO20.3-1.0％、F-0.1-0.5％、Cl-0.1-1.0％、CeO20.05-1.0％、TiO22-4.5％、Fe2O30.5-1.2％和还
