Two people can have the same prescription and need different glasses. Frames sit differently on different faces, and lenses have to be positioned for the eyes actually looking through them.
That is most of the reason a new pair can feel wrong even when the prescription is right.
Start with how you use your eyes
Before frames, it helps to know what the glasses are for.
Someone who spends the day on a computer needs something different from someone who mostly drives. Someone in their forties noticing that small print has moved farther away needs a different lens design than someone who has worn a single prescription for twenty years.
Tell our optical team how you spend your day. It changes the recommendation more than anything else.
Lens designs
- Single vision. One prescription across the whole lens. Simple and effective when you need correction at one distance.
- Progressive. Distance at the top, intermediate in the middle, reading at the bottom, blended without a visible line. Positioning matters a great deal here, because the corridor you look through is narrow.
- Occupational and computer lenses. Optimized for arm's length and near work. Often a good second pair for people who spend long hours at a desk.
Coatings and materials
Coatings are not upsells when they are matched to how you actually live.
- Anti-reflective reduces glare from headlights and screens and makes your eyes more visible to other people.
- Scratch-resistant treatment matters for anyone who is hard on glasses.
- Photochromic lenses darken outdoors, useful if you would rather not switch pairs.
- Polarized sunglasses cut glare off roads and water.
- Thinner materials keep a stronger prescription from becoming a heavy lens.
Measurement
A lens has an optical center, and it needs to line up with your pupil. If it does not, you look through the edge of your own lens. If you want to read your own prescription, see what the numbers mean.
We use iTerminal 2 for this. It takes five measurements rather than relying on pupillary distance alone, capturing how a frame sits on your face and where you look through it, so lenses can be positioned more precisely.
We also use iProfiler, which measures optical characteristics that can help refine the prescription and support personalized lens design.
Frames that fit
A frame should sit level, stay put without being tight, and keep your eyes reasonably centered in the lens.
Our optical staff does this all day and will tell you honestly when a frame is not working, whether that is fit, your prescription, or how it sits on your face. Patient reviews often mention the help they get choosing frames, and we would rather spend the time than have you come back unhappy.
Common questions
How long will my glasses take?
Timing depends on your insurance and the lab required by your plan. Some glasses are made by an outside lab. Call our office for the latest update on your order. More detail in how long it takes to get new glasses.
Why do my new glasses feel strange?
Some adjustment is normal, especially with a new prescription or a first progressive lens. If it has not settled within a couple of weeks, come back in. Something may need adjusting. See why new glasses sometimes feel strange at first.
Does CenCal cover glasses?
CenCal eyewear benefits may apply depending on eligibility and coverage. Call our office and our team can check for you. See does CenCal/Medi-Cal cover eye exams and glasses.
Can I bring my own frame?
Ask us. It depends on the frame's condition and whether it suits your lens design.
Do I need a separate pair of sunglasses?
Not necessarily, though many people prefer prescription sunglasses for driving. Photochromic lenses are the alternative.
