Goldman's lenses help to keep eyesight

Vision helps us to admire the beauty, to see how close people are changing with age. Without him, it would be difficult to comprehend the basics of science and read your favorite books. A person receives a lot from the visual organ, but forgets that vision also requires attention, at least sometimes. To conduct an examination of the visual organ can be using the lenses of Goldman.

What it is

Before you go through any procedure, you should at least a little learn about it and the equipment on which it will be conducted. In this article, you will learn what Goldman lenses are . This device is used to examine the fundus, the angle of the anterior chamber, also for stereoscopic observation of them and laser coagulation of their structures.

The device consists of three mirrors, which are rotated at angles of 59, 66 and 73 degrees. This arrangement of mirrors makes it possible to simultaneously explore different areas of the eye, since light is refracted in a special way. Proceeding from this, it can be said that the Goldman lenses will help to check those corners of the eye, which in other methods can not be investigated.

It is desirable to conduct such surveys:

• People who are engaged in extreme sports;
• Future mothers;
• To old people;
• Those who received eye trauma.

What is the procedure for?

Most often, the examination of the fundus by the Goldman lens is performed in conjunction with other methods of ophthalmology. Only in this case the doctor can get a complete picture of eye health. During the examination, special drops are used, which dilate the pupil. After the procedure, you can not sit behind the wheel and do work, which gives a load on the eyes. When the Goldmann lens is used, the survey will be complete. The doctor, using this device, diagnoses the patient's retina without problems, and this must be done before the ophthalmic operation.

The advantage of this method is the ability to study in detail the peripheral parts of the fundus and diagnose at the initial stage dystrophic changes and detachment of the retina. This is very important for eye health. As soon as you notice a worsening of vision, persistent shivers before your eyes, or if your head starts to ache after eye strain, immediately consult a doctor. At the initial stage, many diseases can be cured.

Care of lenses

Goldman's lenses should be sterilized. To do this, a six percent hydrogen peroxide solution is used. The outer surface of the lens is chemically disinfected. To a 3% solution of hydrogen peroxide, 0.5% detergent solution is added.

Optics are cleaned with a mixture consisting of 85% alcohol and 15% ether. From the surface of the lens, dust is removed with a degreased brush. Be sure that the lens is not subjected to mechanical and thermal stress.

During operation, the lens must be held by the frame, it is impossible to touch the optical surfaces.

It is forbidden:

• Wash the lenses with alcohol.
• Rinse with water with a temperature of less than 5 and above 30 ° C.
• Keep near heat.

Conclusion

Do not forget that your eyes too require attention. And even if at the moment they do not fail you, but it is worth to examine them. After all, the disease can hide somewhere inside and manifest unexpectedly.
