When Wearing Contact Lens
There is always an adapting period for wearing contact lens. First wearers or someone who returns to wear the contact lens after having not worn them for some time may feel something in their eyes. In the adapting period, the time for wearing the contact lens should be increased step by step. Generally, contact lens should be started wearing from 4 hours every day, 2 hours added each day after.
If there is no uncomfortable feeling, the patient could go to the hospital for a counter checking in 4 or 5 days. If the checking result is all right, the wearing time can be lengthened to a whole day. However, it still should be controlled in 14 to 16 hours a day, no wearing during sleeping time.
When touching the contact lens, patients should at first cleaned their hands with soaps and remember trimming the nails in time to avoid harming the lens or the cornea. It’s easy for contact lens to get viruses and epiphyte on the surface and they should be disinfected every day. The lens should be put in storing cases filled with preserving fluid and remember to replace the fluid every day, plus cleaning the cases regularly.
Protein in tears may be attached to the lens and the patients should use certain dose to get rid of it at least once a week. Female users should pay attention that the lens could be polluted by cosmetics. Besides, before or during wearing the lens, pay attention not to use the eye drops because some eye drops may color the lens or the preservative may contract and hurt the cornea.
The tending work and timely visit to hospital are quite important for wearing contact lens. Prompt and regular countercheck helps to know the health status of eyes and reactions to wearing contact lens. Thus it can help to wear more safely. For that the contact lens will touch the cornea closely, and may result in exfoliation of corneal epithelium, macropapillary conjunctivitis and other diseases.
Besides, the patients can judge whether they have properly worn the contact lens by seeing if they can see clearly, feeling comfortably and the eyes are not red after having worn the lens.
