Chinese Medical Sciences University attaches to and holds the ophthalmology professor in Beijing hospital the beautiful female contact lenses gain the name because it is thin and and transparent, difficult to find in summer, usually used for correcting near-sightedly. But because contact lenses contact cornea directly, improperly use, will cause the intersection of eyes and red, itch, photophobic, shed tears, the intersection of foreign matter and the intersection of sense,etc. and symptom, the serious one loses one's sight because of keratitis, corneal ulcer. So should pay attention to: In front of going to the hospital to check eyes and wear the contact lenses for the first time regularly, should ask the oculist to check eyes in an all-round way, get rid of diseases such as glaucoma, chronic dacryocystitis, conjunctivitis, keratitis, corneal ulcer,etc., and reexamine once every half a year. If find that has already suffered from and finished membrane inflammation, should treat and fully recover, wear the contact lenses. Choose the contact lenses contact lenses of high oxygen rate to worn on cornea, the supersession of the cornea needs oxygen under the normal situation, 80% oxygen needs getting from the air, the contact lenses isolate the contact of cornea and oxygen, will influence the supersession of the cornea as a protective screen. Certainly completely oxygen good impact on oxygen supersession of cornea of contact lenses will stand opposite each other a little smaller. Generally, with color contact lenses completely oxygen nature poor than transparent contact lenses. The contact lenses choosing water content to be moderate are in theory, the contact lenses of the same material, the higher water content is, completely the better oxygen performance is, the softer the lens is, wear the more comfortably. So, the higher a lot of people's simple water content which is interpreted as the lens is, the better a lot of people's simple water content which is interpreted as the lens is. It is not in fact like this. Person that eyes do not do suitable for the intersection of water content and high contact lenses relatively, if it is person that eyes do that should use water content to be low. Because contact lenses with high water content do not produce water, it is a kind of spongy macromolecule structure, to absorb water into the eyeball. Water content higher than 50% will lead to the fact lens it exchanges damage to be and out of shape, easy to adhere to precipitate such as protein usually, correct ability to be poorer, etc to astigmatism. Select the change type contact lenses of short cycle for use in the course of using the contact lenses, the impurity or foreign matter in composition, secretion, external environment condition in people's tears liquid affixes to lens and forms the precipitate unavoidably. Even attend to and wash according to the procedure strictly, it is unable to remove to still have invisible precipitate of naked eye to remain on the lens. As time passes, the precipitate not only will influence the comfortableness worn, will influence the health of the eye even more. So, the contact lenses which use moon throwing or shorter change type of throwing cycle than the moon are safe. Wearing the contact lenses contact lenses for a long time should be replaced and used with the frame glasses. Wear the contact lenses for about half a year each time, should wear frame glasses for one month, let the eyeball be abundant " Have a rest " . With crook uneven light ' The near-sighted degree of eyes differs by more than 200 degrees) Ones that can't wear frame glasses, had better choose to allow the molecule laser operation to remove the glasses. Let alone the contact lenses of the beautiful pupil are worn for a long time, in case that pigmentation is in the eyeball. In addition, women are in menstrual period, pregnancy period, the cold, organism immunity are unsuitable to wear the contact lenses while dropping. (Yan Hong puts in order)
