Visionstar TF-5270

High-volume adult refraction suits a durable fixed-PD set, and metal construction means the frames hold true across years of daily handling rather than gradually drifting.

Patients with unusually high or low nose bridges benefit directly from the pad height adjustment, since a fixed frame would otherwise sit their optical centres noticeably above or below the pupils.

Higher prescriptions are where vertical centration matters most, because induced vertical prism grows with lens power, and this set addresses that where most fixed-PD frames cannot.

Binocular vision assessment depends on accurate centration in both directions, so vertical error that would pass unnoticed in a routine test can confuse a clinician looking for vertical phorias.

Occupational health and screening programmes refracting adults at volume gain from a set that combines quick selection with a proper fit.

Teaching clinics can use the pad adjustment to demonstrate vertical decentration and its prismatic effect directly.

Young children below 52 mm fall outside the scale and need a paediatric frame.

Long refractions on frail patients may favour a lighter frame, since metal is typically heavier than plastic and the weight is not yet published.

Vertical centration, not just horizontal

Adjustable nose pad height brings the optical centres level with the pupils, which a fixed frame usually cannot.

Holds its alignment

Metal construction resists the gradual flexing that moves plastic frames out of true over time.

Four lenses per side

A full prescription can be built without swapping lenses mid-test.

Adjustable temples

Frames sit square and at a sensible vertex distance on different head sizes.

Ten sizes

52 to 70 mm covers most adults and many older children in 2 mm steps.

Broad, steady temples

Paddle-shaped arms spread contact behind the ear and help the frame sit still.

Suits binocular work

Accurate centration in both directions avoids introducing a vertical prism that could be mistaken for a phoria.

Built for daily handling

Metal tolerates repeated use and cleaning better than softer materials.

Its gaps stated plainly

Weight, box composition and cell diameter are flagged here rather than left to assumption.

Metal construction

Silver metal frames, as shown in the photograph. The specific metal is confirmed at order.

Adjustable nose pad height

Pads raise and lower to set vertical centration.

Adjustable temple length

Paddle-shaped temples adjust in length.

Four lenses per side

Four cells each side accept lenses simultaneously.

Ten fixed PD sizes

52, 54, 56, 58, 60, 62, 64, 66, 68 and 70 mm, in 2 mm steps.

Five pairs per box

Which five sizes are supplied together is confirmed at order.

Cell markings

Printed scales visible around each cell. Whether axis calibration is fitted is confirmed at order.

No interpupillary adjustment

Fixed horizontal centration by design.

Weight

Not published. Obtained before supply.

Cell diameter

Not published. Confirmed against your trial lens set at order.

Approved cleaning agents

Not published. Obtained before supply.

Coverage limits

Nothing below 52 mm or above 70 mm; patients between steps fitted to the nearer size.

The Visionstar TF-5270 is a metal fixed-PD trial frame in ten sizes from 52 to 70 mm, with four lenses per side and two adjustments most fixed-PD frames lack: temple length and nose pad height. The pad height is the one that matters clinically, because a fixed PD sets horizontal centration only, and bridge height varies enough between patients to move the optical centres several millimetres vertically. Metal construction keeps the cells true through years of handling. It suits high-volume adult refraction, higher prescriptions and binocular vision work. Weight, cell diameter and which five sizes arrive in each box are all unpublished, and Medigear.uk confirms each in writing. Contact the Medigear.uk team for pricing and box composition.
