Scope of Application, Composition, Features and Contraindications of the Product

1.1 Scope of Application
It is used to increase the operator's viewing angle for easy observation of object details.
1.2 Structural Composition
It is composed of an optical system and a frame, using the principle of lens magnification and the principle of microscopic magnification of optical magnifying devices.
1.3 Features
The magnifying lens uses high - quality optical glass with multi - layer anti - reflection film, which has high light transmittance and clear wide - field images.
The long working distance, clear, bright and wide field of view provide convenience for various fine work.
The 0° - 82° angle adjustment structure ensures that the magnification angle can be adjusted arbitrarily to meet the requirements of various postures and reduce discomfort in the head, neck and other parts.
The up - and - down adjustment structure of the frame (with a maximum displacement of 11 mm) meets the personalized needs of doctors during operation. Adjusting the interpupillary distance alone can adapt to various eye shapes.
It can be integrated with all types of headlamps produced by Hunan Micat Technology Development Co., Ltd.
This product is exquisitely designed, beautiful in shape, convenient to operate and easy to carry.

Installation and Usage Methods

First, fasten the anti - slip spring of the medical optical magnifier tightly at the end of the two eyepieces to fasten it behind the ears. After wearing the medical optical magnifier, the support of the frame should be close to the nose bridge, then adjust the length of the eyeglass rope, and finally fasten the anti - slip rope.
Wear the medical optical magnifier on the doctor's head and adjust the interpupillary distance.
The user adjusts the distance between the two eyepieces according to his own interpupillary distance, so that the relevant interpupillary distances are distributed on both sides of the track, and then wears the medical optical magnifier and ensures that the two eyepieces are distributed on both sides of the eyes according to the interpupillary distance, so that the observation fields of the two eyepieces overlap.
Now observe three - dimensional objects (not text or circles) with a single eye respectively.

If the two eyes cannot observe the same round - shaped object, adjust the up - and - down position by turning the fine - adjustment knob of the up - and - down position adjustment structure of the eyepiece frame. Adjust the angle by turning the angle adjustment structure of the eyepiece frame. After the up - and - down position and angle are adjusted, slightly turn the interpupillary distance adjustment left and right screws to ensure that both eyes can see the same clear, round and three - dimensional object.
If the two eyes still cannot see the same clear, round and three - dimensional object (i.e., there is a double - image difference).

At this time, continue to turn the interpupillary distance adjustment left and right screws to slightly adjust the angle of the eyepiece until both eyes can see the same clear, round and three - dimensional object.
Cleaning of the lens: Use lens paper or absorbent cotton dipped in a mixture of 50% ethanol and 50% distilled water to gently wipe the lens clean (wiping from the center in a spiral shape outward). If there is dust on the lens, it can be blown away with a rubber air - bulb or removed with a dusting pen.
Attention: Do not allow liquid to seep into the product.
