How to put on and remove contact lenses

In order to properly and quickly wear contact lenses require some dexterity. People who face this the first time, they say that at first there is even a slight sense of fear - what if you can accidentally scratch the eye. Ophthalmologists same argue that this is unlikely, if cautious. 

Plus, an eyelid when trying to install the lens on the eyeball reflexively closes, which complicates the task. But fear not need - with time to develop the skills and putting on the lenses, as well as their withdrawal, will be a habit. A "novice" should remember a few helpful hints. 

First, you should not wear lenses on the "sleepy" eyes. Lack of sleep leads to the fact that the tension in the eyeglasses of increases, there is a slight feeling of colic, and the lens in such a situation may provoke irritation. 

Secondly, it is highly undesirable to confuse the lens, even if they both have the same diopter. To avoid this, it is better to teach themselves always start the installation and removal of lenses with the right eye. Moreover, the lens should be withdrawn immediately put in the right department of the container store them, and then taken over his left eye. 

Thirdly, it is most convenient when putting the lens to keep it on the tip of the finger tips. At the same time make sure that it not turned inside out - "right" lens has the shape of the bowl, its edges are directed upwards. By the way, some well-known manufacturers invented to mark their lenses special mark to indicate which side of the external and what is inside. 

Fourth, before you put the lens on the eye, it must consider carefully and make sure it is clean - it should not be grains of sand, dust, hairs, which can cause discomfort and irritation of the eyeball. 

This is interesting:
The most important rule that you need to remember everyone who uses contact lenses - worn and removed need only clean dry hands. Modern lenses have a porous structure, therefore easy to absorb the micro-particles of dirt, sweat, grease. A because they have direct contact with the surface of the eye, the mud may lead to allergies, irritation or infection. 

As for the technology to put on contact lenses, it can be done either one hand or two. Which method is more convenient, everyone chooses. 

To put the lens with one hand, you must first pull the lower eyelid right middle finger, then move upward glance, and Then gently apply the lens to the white of the eyeball, just below the pupil. By removing the index finger on the lens should be slowly omit look down - the lens itself must take the place, that is the center of the eye. This will be felt immediately. When should carefully 
release eyelid and blink a few times slowly, to lay down the lens closer to the cornea. If not the feeling of discomfort and eye was good to see, then, the lens has been installed correctly, and you can move to the left eye. 

To wear my contact lenses with two hands, to the middle finger of his left hand pull the right upper eyelid up. Medium finger of his right hand is near the lashes of the lower eyelid and gently diverts eyelid down. Index finger of right hand lens is gently applied to the eyeball. Without releasing the century, you need to delete the view down to the lens fell exactly in the center. 

Then should blink a few times and repeat the operation with the other eye. Typically, the lens is easy to take the right position in the center of the cornea. But it happens that they are shifted to the side - to understand this You can, if the eye appeared unusual sensation, and the image of objects is unclear. Centered position of the lens be as follows: eyes closed, gently massaging the eyelid in a circular motion. The surface of the lens is smooth, so is easy to slip on wet eyeball. 

Remove contact lenses is somewhat simpler than wear. Middle finger of his left hand pulling the right lower eyelid down to make the index finger of his right hand to the bottom of the lens, then move it to the side or down gently to squeeze between the thumb and forefinger and remove from the eye.
