COIL is one of the most respected names in low-vision optics. Made in Britain, COIL magnifiers are the kind optometrists and low-vision clinics reach for when image quality genuinely matters. They cost more than supermarket magnifiers, and the optics show exactly why.
Why optometrists recommend COIL
COIL lenses are made to optical standards, not novelty standards. Edge-to-edge clarity, minimal distortion, and accurate magnification mean the user sees a clean, sharp image across the whole lens. For someone with macular degeneration straining to read, that quality difference is the difference between coping and giving up.
The COIL range
COIL makes hand-held magnifiers, stand magnifiers, bar and line magnifiers, and high-power aspheric lenses. Many models come in both daylight and LED-illuminated versions. The aspheric designs are built specifically for low-vision use, giving high magnification with the widest possible field of view.
Aspheric lenses for low vision
COIL pioneered aspheric magnifier lenses, which are shaped to reduce the distortion that normally appears at high magnification. The result is a stronger lens that still gives a usable, clear field of view. This is why COIL is a clinic favourite for serious sight loss.
Illuminated and non-illuminated
COIL illuminated magnifiers add bright, even LED light through the lens, which lifts contrast and removes shadow. Non-illuminated daylight models suit users with good room lighting who want the lightest, simplest tool. Both share the same quality optics.
Who COIL suits
COIL suits anyone who needs dependable, clinic-grade magnification, especially people with diagnosed low vision. If an optometrist has recommended a specific magnification, COIL is one of the brands most likely to deliver it accurately.
