In the production of contact lenses, the lens material is heated to the point of melting. The liquid lens material is then injected into a pre-cut mould. The material solidifies to the shape of the mould once the lens material dries. The lens will be polished, then inspected to check its standard of quality.

Composition of Soft Contact Lenses. The first soft contacts were made in the 1960s of a hydrogel called polymacon or "Softlens." This is a polymer made of 2-hydroxyethylmethacrylate (HEMA) cross-linked to ethylene glycol dimethacrylate. The early soft lenses were about 38% water, but modern hydrogel lenses may be up to 70% water.

Contact lenses work by correcting vision through the use of a small, curved lens that sits directly on the eye's surface. The lens is designed to refract light in a way that corrects the eye's refractive error, which is what causes blurry vision. Contact lenses can be used to correct nearsightedness, farsightedness, astigmatism, and presbyopia.

The process of lathe cutting starts with the small disks of raw plastic material which are placed on a rotating shaft. The shaft spins the plastic material at a high velocity while automated tools carve out the shape of the lenses. Once the shape of the lens has been made, the lenses are polished and hydrated in order to arrive at the soft.

Both the cutting and polishing processes are carried out first on the concave inner surface and repeated on the lens' convex outer surface. After the front and rear surfaces are finalised, the lens is removed from the lathe and hydrated to make it softer. Quality assurance testing is performed on the finished lenses.

Soft, hard, and hybrid contact lenses are all made using types of plastic, but maybe not the kind of plastic that comes to mind when you hear that word. Different types of contacts are made using various high-tech polymers that allow oxygen to flow through to reach the cornea—a necessity when it comes to eye health.. In this guide, we'll examine the materials used to make contact lenses.

Injection molding. In this process, the soft contact lens material is heated to a molten state and is then injected into computer-designed molds under pressure. The lenses are then quickly cooled and removed from the molds. The edges of the lenses are polished smooth, and the lenses are hydrated to soften them prior to undergoing quality.
