Prescription lenses enhance visual clarity in people with refractive errors like nearsightedness, farsightedness and astigmatism. Aside from providing clear vision, they can also help protect your eyes from harmful UV rays and glare. If you’ve ever wondered what’s involved in creating your glasses, you’re in the right place.
Keep reading to discover how experts craft prescription lenses.
Prescription Verification
Getting the correct prescription lenses starts with a comprehensive eye exam. Your eye doctor will perform various tests and take measurements to determine your visual acuity. These specifications are integral to creating lenses tailored to your precise vision needs.
Lens Material Selection
After the examination, the next step is to select the appropriate lens material. Your optometrist will help you choose the best lens material based on your prescription, comfort and personal style.
Lens Blocking
Blocking refers to mounting the lens on a device that keeps it secure and stable throughout the cutting and shaping process. It requires precision to ensure the prescription lenses will provide the correct vision correction.
Lens Surfacing
A surfacing machine shapes the lens to match the exact prescription provided by your optometrist. This delicate process involves removing excess material from the lens to achieve the precise thickness and curvature necessary to correct your vision.
Lens Finishing
The finishing process gives your lenses a smooth, polished look and feel. It’s where experts buff rough edges and eliminate any imperfections. They polish lenses until they are smooth, so you see clearly when you look through them. This step also prepares the lenses for any coatings that may be applied, such as anti-reflective or anti-scratch coatings.
Lens Edging
After surfacing the lens, it will be edged and cut down to the size and shape of your eyeglass frames. An edger trims the lens down to the exact specifications of your frames. This step is critical to ensuring your glasses fit comfortably and function correctly.
Quality Control
Prescription lenses undergo a strict quality check to meet specified requirements and standards. Professionals inspect the lens for defects and check the prescription accuracy. They confirm that the lens fits perfectly within the frame. The lenses are also evaluated for clarity, comfort and durability.
