How Opticians Use Lenses To Correct Refractive Errors

This week we look at how opticians use optical lenses to correct the refractive errors of the human eye. In part 3 of our series, we show simple lens shapes in front of the eye and how they redirect light to correct vision. Optician training includes an understanding of lens design and the refractive errors. We cover the topics of plus lenses, minus lenses, lenses that correct astigmatism and presbyopia.

The only exclusively uncut lab in the country; we provide our customers with independent, high-end alternatives to corporate brands. Through craftsmanship, technology, and independent, innovative vendors like Younger, IOT, A&R, and Quantum Innovations we offer our customers the Integrity portfolio of freeform lenses and coatings. Made in the USA, the Integrity brand is not a generic house-brand, but is the absolute best available, designed to give the wearer that “wow!” experience. In addition to the digital line, we still offer conventional surfacing, including glass. Maintaining traditional equipment gives our customers vastly more flexibility in their dispensing, particularly when it comes to more difficult prescriptions. Learn More: http://www.laramyk.com
