A Sneak Peek Into How Prescription Lenses Are Made

Your eyewear process starts with understanding the prescription, which holds all the necessary information to shape your lens correctly. This tiny piece of paper comprises distinct details that guide opticians in creating well-fitted lenses for your unique visual needs. In this post, Insight Vision Center Optometry, a trusted optical shop and vision therapy clinic, discusses the process of creating prescription lenses.

Selection of Raw Material for Lenses

Lenses were historically made out of glass, but today’s lenses are usually made of advanced materials like plastic and polycarbonate. These lightweight materials offer more safety and comfort, making them ideal for everyday wear.

Molding of Lenses

One of the significant steps in the lens-making process is molding. Expert technicians carefully pour liquid lens material into a mold shaped according to your prescription. The result is perfectly curved lenses, ready for further detailing.

Surfacing of Lenses

Surfacing is the process that tailors a lens specifically to your prescription. This technique involves generating or cutting the lens into a rough curvature, followed by fine grinding and polishing to achieve a lens surface that will bring your world into focus. Expect the process to be different if you’re getting scleral lenses.

Lens Treatment

After the lens is shaped and surfaced, it’s time for the specialized treatments that improve your vision and maintain lens durability. Anti-glare, scratch-resistant coatings, or UV treatments are applied to the lenses, greatly enhancing your vision.

Quality Control

Before the lenses are packed and shipped, they undergo rigorous quality control. Opticians check for accurate prescriptions, smooth finishing, and the functionality of the applied treatments, ensuring you receive quality lenses.

Fitting the Lenses Into the Frames

Your lenses are carefully fitted into your chosen frame. A precise device cuts your lens into the perfect shape to fit your frame snugly, ensuring your glasses are as comfortable as they benefit your eyesight.
