The quick answer
Compare the task before comparing lens upgrades
| Compare | Reading glasses | Computer glasses |
|---|---|---|
| Usual task | A prescribed near task, such as a book | A prescribed screen or workstation task |
| Working distance | Your actual reading distance | Your actual monitor distance and layout |
| Prescription | Written for the near task | Written for the workstation task when needed |
| Other viewing | Not assumed to cover a room or the road | Not assumed to cover every desk and room distance |
| Coatings | Optional choice after prescription and fit | Optional choice after prescription and fit |
The American Optometric Association’s computer-vision guidance notes that an existing reading or distance prescription may not suit a computer’s viewing distance. That is a reason to discuss the setup, not to change your prescription yourself.
Describe the ordinary desk, not an ideal photograph
Note where you sit, the distance to the main screen and whether you regularly look at a second display or a printed page. Include laptop use if it is a large part of your day. These details help your provider understand the task.
Keep the measurement practical: use your normal posture and setup rather than moving the screen unusually close so your old readers work. If you also need clear vision across the room, say so. A dedicated pair may not answer every distance requirement.
A different setup can create a different fit question, too. Compare the bridge and frame size with a comfortable pair and check any headset contact points separately from lens power.
Computer glasses is not another name for blue-light glasses
Prescription power, anti-reflective coating and blue-light filtering are separate features. A blue-light filter does not turn an unsuitable prescription into the correct workstation prescription.
Read the actual lens description instead of assuming a screen-use label includes every option. Our computer and blue-light glasses guide discusses that distinction, while the reflection comparison helps separate lens reflections from a lamp reflected on the monitor.
Do not treat a coating purchase as a guaranteed cure for screen discomfort. Persistent symptoms or blurred vision call for an assessment of the underlying cause.
Order the pair your prescription describes
Fast Eyeglasses offers eligible corrective single-vision lenses only. We do not currently offer progressive or occupational multifocal lenses, bifocals or prism. Contact us before ordering when the document or intended task needs clarification.
Use the measured PD and task information supplied for the pair. Do not reuse a reading adjustment for a computer pair without checking. See our custom reading glasses comparison for the reader question and single-vision ordering information for current options.
Everyday base pairs start at $79, with upgrades and applicable stronger-prescription charges extra. Check the full configuration and return terms before committing to custom lenses.
Common comparison questions
Can my reading glasses work at a computer?
They may or may not suit the task. Ask your eye-care professional using the actual screen distance rather than assuming the two prescriptions are interchangeable.
Does adding blue-light filtering make readers computer glasses?
No. A filter does not determine the prescribed lens power or the working distance it suits.
