Choosing an Optician and Understanding Eyewear Costs
Eyecare combines a clinical examination with a retail transaction, and separating the two clarifies what you are paying for.
The examination
A sight test checks refraction and also screens for eye disease — glaucoma, cataract, macular changes — and can detect signs of systemic conditions including diabetes and hypertension.
That health screening is the more important function, and it is the reason to attend regularly even when vision seems unchanged.
Intervals are commonly every one to two years, more frequently with certain conditions, family history or increasing age.
Free or subsidised examinations exist for various groups in many systems, and eligibility is broader than people assume.
Your prescription belongs to you
After an examination you are generally entitled to a copy of your prescription, and you may take it elsewhere to have eyewear made.
Ask for the pupillary distance measurement as well, since it is required to make glasses and is not always volunteered.
This matters because eyewear prices vary enormously for the same prescription.
Where the cost sits
Frames are largely a fashion purchase, and margins are substantial. Comparable quality is available across a wide price range.
Lenses are where the technical differences lie. Higher index materials are thinner for strong prescriptions. Coatings — anti-reflective, scratch resistant, ultraviolet — vary in quality and durability.
Progressive lenses vary considerably in design quality, and the better designs genuinely offer wider comfortable zones. This is one area where paying more delivers something.
Blue light filtering coatings are heavily promoted, and independent reviews have generally found limited evidence for meaningful benefit on eye strain or sleep.
Online versus in person
Online suppliers are considerably cheaper for straightforward single-vision prescriptions.
Complex prescriptions, progressives and anything requiring precise fitting heights benefit from in-person measurement, since errors are common and the lenses cannot be adjusted afterwards.
A reasonable approach is in-person for primary complex eyewear and online for spare pairs, prescription sunglasses or simple prescriptions.
Practical points
Two pairs at a moderate price frequently serves better than one expensive pair, since glasses get lost and broken.
Ask what the warranty covers and whether adjustments are free.
Keep the prescription and note when it expires, since suppliers require a current one.
