Optometry equipment built for adjustable, accurate refraction testing. Aist Optics Trial Lens Frame keeps clinicians and patients comfortable during longer assessments thanks to an ultralight titanium build and straightforward adjustment controls. Is it suited to routine clinic work and teaching?
⚡ At a Glance
- • Adjustment Range: Interpupillary distance 48-80 mm, single-eye 24-40 mm, 1 mm scale increments
- • Best for: Optometrists, optical students and small clinics needing manual refraction tools
- • Not ideal for: Users who need automated or digital refraction systems with integrated electronics
Ultralight titanium frame weighs 50g and accepts up to five lenses, three in front and two in back. Multiple mechanical adjustments allow accurate fitting and on-frame measurement for corneal vertex and inter-eye distance.
Precise alignment - with adjustable interpupillary range
Interpupillary distance adjusts between 48-80 mm with single-eye settings from 24-40 mm and 1 mm scale markings for repeatable positioning. Separate controls for left and right eye allow independent centring.
Faster, more accurate refractions and fewer retests thanks to repeatable alignment, useful during busy clinics and teaching demonstrations.
Comfort for extended exams - with ultralight titanium frame
Titanium construction keeps overall weight at 50g while remaining robust; temple length and anterograde angle are mechanically adjustable for a tailored fit. Lightweight materials reduce pressure on the nose and ears.
Patients tolerate longer testing sessions with less discomfort and clinicians can adjust fit quickly across a wide range of face shapes.
Organised testing and quick lens changes - with five-lens capacity and measurement scales
Frame accepts three lenses in the front and two in the back, permitting stacked lens combinations during refraction. An inter-eye distance ruler and a corneal vertex measurement scale on the frame support on-the-spot calculations.
Keeping lenses in place and having measurement scales on-frame helps speed up routine refractions and makes demonstrations clearer during training.
✨ The 4 Key Reasons for Aist Optics Trial Lens Frame
- Titanium construction - Keeps frame weight at 50g for improved patient comfort
- Five-lens capacity - Hold up to 5 lenses for rapid prescription adjustments
- Pupil height adjustment - Fine-tune lens height for accurate centration on any face
- Inter-eye distance ruler - Measure and record PD quickly without extra tools
