Required Education

While there are no formal education requirements for becoming a precision lens grinder, many successful entrants into the field have earned 1-year vocational certificates or associate's degrees in ophthalmic technology. These educational programs typically involve classes in eye anatomy and practical experience with grinding equipment and measuring devices. The Association of Technical Personnel in Ophthalmology offers continuing education credits that can help precision lens grinders advance their careers. It may also be possible to obtain a position as a precision lens grinder through an apprenticeship.

Skills Required

Precision lens grinders are dexterous and capable of performing exacting work where every detail counts. Precision lens grinding involves repetitive motion and long periods of focus. Precision lens grinders must be capable of working efficiently and independently.

Career and Economic Outlook

Though the number of eyewear prescriptions is expected to increase as the population ages, the affordability and availability of laser correction for vision problems will balance the need for precision lens grinders, according to the U.S. Bureau of Labor Statistics (BLS). Employment opportunities for ophthalmic laboratory technicians are expected to grow at a faster-than-average rate compared to other career fields - 10% - from 2014-2024, per the BLS. Ophthalmic laboratory technicians, including precision lens grinders, earned a median annual wage of $29,860 as of May 2015, according to the BLS.

Dispensing Optician

A dispensing optician helps vision care patients choose appropriate eyeglass frames and contact lenses based on the prescription written by an optometrist or ophthalmologist. He or she makes recommendations as to frame style or lens treatments as needed and takes measurements for eyewear work orders. Dispensing opticians also advise customers on the fit, care and repair of their eyewear. Dispensing opticians may receive on-the-job training or complete a postsecondary certificate program. State licensing may be required; professional certification is also available in dispensing eyeglasses and contact lenses. The BLS estimates that jobs in this field will increase 24% from 2014-2024; dispensing opticians earned a median annual pay of $34,840 in 2015.


An optometrist provides eye care to patients, including diagnosing eye diseases, illnesses and conditions like glaucoma; conducting vision tests; prescribing corrective lenses in cases of near- or far-sightedness; and treating eye injuries. Optometrists may also provide pre- or post-surgical eye care. However, optometrists don't perform eye surgery, though ophthalmologists do. Optometrists usually earn bachelor's degrees and then 4-year Doctor of Optometry degrees. State licensure is required. American Board of Optometry certification is also available. Optometrists can expect job growth of 27% from 2014-2024, per the BLS. They earned a median annual salary of $103,900 in 2015.
