Discomfort with new glasses can be part of normal visual adaptation, but frame position, lens power and design, vertex distance and fitting problems should be separated and checked.
01 · FRAME POSITION
A new frame may place the lenses differently from the old one
Different bridge height and frame width can change wearing height and the distance between the eyes and lenses.
Even with the same prescription, a higher or lower frame position or a different vertex distance can make vision and comfort feel different.
02 · LENS POWER
A prescription change can alter visual sensation
Changes in myopia or hyperopia correction, astigmatism power or axis can make floors, objects or spatial relationships feel different at first.
Larger changes may require a period of adaptation.
03 · LENS DESIGN
The lens design may also have changed
Changing from spherical to aspheric lenses, from single-vision to progressive lenses, or between progressive designs can change peripheral vision and head movement patterns.
Progressive lenses are particularly sensitive to wearing height, pantoscopic tilt, vertex distance and frame alignment.
04 · VERTEX DISTANCE
Has the distance between the lens and eye changed?
Vertex distance changes the effective wearing relationship between the lens and eye.
With higher prescriptions, a change in vertex distance can be felt more strongly, so compare the new and old glasses.
05 · FITTING OR ADAPTATION
Separate fitting problems from visual adaptation
Severe nose pain, pressure on only one temple or an obviously tilted frame are not typical visual adaptation issues.
A new prescription or lens design can feel unfamiliar and may need time.
If discomfort does not improve, or if there is severe dizziness, double vision or visual discomfort that interferes with daily activities, recheck lens power, centration, design and the fitting instead of assuming it is normal adaptation.
SOLUTION GUIDE
Solutions at a glance
Compare wearing height and vertex distance.
Consider adaptation while reviewing what changed.
Check fitting first.
Recheck the lenses and fitting.
GLANOS FITTING CHECK
GLANOS fitting check order
- Front
Check frame alignment. - Nose pads / bridge
Check wearing height and vertex distance. - Width
Make sure the frame remains stable. - Temple bend
Make sure the wearing position does not keep changing.
CAUTION
Do not assume every problem is adaptation
Some visual changes need time, but severe pain or persistent visual discomfort deserves a recheck. With progressive and high-prescription lenses, actual wearing position is as important as the lens itself.
