Generally, hand crafted eyewear can be made from two type of materials, e.g. Acetate and Celluloid. Nowadays, almost all European and American manufacturer use acetate for eyewear production. It is because of the limitations of celluloid. Such as low plasticity, difficult in dyeing, long period for material maturation and highly flammable. Accordingly, only Japanese manufacturers insist to use celluloid as the building block for eyewear.

一般来说，手造眼镜可以用两种材料制成，第一种是醋酸纤维，第二种是赛璐珞，现时差不多全部欧美国家都采用，因为赛璐珞有著许多缺点，例如：可塑性低，不易染色，待料时间长，与及高易燃性，所以在60年代欧美眼镜制造商全面禁用此材料而改为使用之后，全世界就只剩日本是唯一还持续使用赛璐珞材料制造眼镜的国家。
