UP UTG kummist silmaümbrus 36, 40, 41.5, 43mm okulaaridele

Highly ergonomic spectacle elastic, made of rubber material with multiple pleats, which provide ample flexibility as a comfortable cushion and protection of the eye area against impact. Designed for devices with approximately 3" eye relief.  Use with optics to reduce eye strain by blocking glare or improving low light, and to improve focus on the target by eliminating distractions caused by peripheral movements that can divert attention. The eyepiece's rubber construction allows for quick eye positioning and alignment of the centre of the optic to speed up target acquisition and increase measurement accuracy. The kit includes a lockable circle to attach to the eyepiece and 3 different thickness inserts to fit devices with 36 mm, 40 mm, 41.5 mm or 43 mm eyepiece diameters.
