Hadley Instruments HTL200 Trial Lens Set
The Hadley Instruments HTL200 features 266 hand-crafted glass lens pieces secured in metal rings. This high quality kit comes in your choice of a leather or aluminum case with removable tray, diopter indicators, and dual combination locks for security. Wide ranging sphere and cylinder powers, two cross cylinder lenses and a variety of accessory lenses will allow you to perform better testing on your entire patient base. This classic form of refraction enhances prescription accuracy for low vision patients in particular, offering accurate vertex distance, which is very helpful for high refractive error patients.
Similarly, any patient who relies on eccentric viewing and needs to move their eyes or head to see around a scotoma can greatly benefit from trial lens refracting.
