‘Can you make me some glasses just for the computer?’
Case Study:
Patient X wanted a consultation due to experiencing eye strain while working at a new job in a call centre, primarily from prolonged computer use. Although they currently wear reading spectacles, they do not require them for distance vision (Driving, TV and Cinema etc). Since Patient X was already scheduled for an Eye Examination, we decided to arrange an appointment with an Optometrist.
Appointment with our Optometrist:
Patient X underwent a comprehensive examination by one of our Optometrists. Following the examination, it was determined that they required an intermediate ADD, which is suitable for viewing a computer screen. Due to time constraints, Patient X deferred selecting glasses and instead scheduled an appointment with our Dispensing Optician for the next day.
Appointment with our Dispensing Optician:
Patient X expressed satisfaction with their current reading glasses but sought a solution to effectively view the computer screen and surrounding paperwork without switching between glasses. The Dispensing Optician (DO) recommended an occupational set of lenses, enabling clear vision of the screen while allowing easy reading of nearby documents through the lower part of the lens. Additionally, the DO suggested applying an anti-reflection coating or a blue filter coating to minimize reflections from the lens surface. Patient X chose a new frame, and the DO conducted precise measurements. To determine the required prescription the DO instructed Patient X to measure the distance from their closed eye to the computer screen at work. Patient X provided the measurements, enabling the DO to calculate a degression of +0.75D.
Collection Appointment:
Ten days later, Patient X’s glasses arrived and underwent a thorough inspection before we contacted Patient X. They scheduled an appointment with the DO a few days later for fitting. Patient X tried on the glasses and expressed satisfaction with the clarity for computer use. They appreciated the convenience of being able to read without switching glasses and planned to assess their performance during their next workday.
Occupational Lenses:
Occupational lenses, also known as ‘computer glasses,’ are tailored to individuals requiring a prescription for close-up tasks while needing clear vision for intermediate distances such as computer screens. Unlike varifocals, occupational lenses are optimized for specific tasks or hobbies, offering a broader field of vision.
Lens Suppliers:
As an independent Optometrist, we have the flexibility to source lenses from various manufacturers. Our primary suppliers include Essilor and Hoya. Essilor, headquartered in Thornbury, and Hoya, located in Wrexham, North Wales, are renowned for their commitment to advancing lens technology and their extensive experience in the field.
