Contact lenses can cause complications
Author： Release time：2018-09-11
Due to the adverse effects of many aspects in real life. More and more people have symptoms of myopia. For myopia, people choose to wear glasses. The development of science and technology has also led to the development of glasses to the level of contact lenses. In normal times, although the contact lens improves the aesthetics, the complications it brings are not something that everyone can meet. Therefore, wear caution!
Red eyes appear, stop wearing immediately
A common symptom that can also occur with a wearer is red eye. The main cause is corneal hypoxia caused by wearing contact lenses, mechanical stimulation of the lens, chemical stimulation of lens deposits, toxicity of pathogenic bacteria or toxicity of the care solution. If you have this symptom, stop wearing it immediately and go to a specialist to check the treatment and remove the cause. If the lens is too much and old, the lens should be replaced. Red eye prevention measures are: contact lenses that are reliable in oxygen permeability, such as contact lenses that have been registered and exported by the state; if the lenses are old and aging, they should be replaced; if the care solution used is irritating, another solution can be replaced; Do not wear the piece for long wear; if the lens is too tight, it should be replaced.
Dry feeling, many reasons
There are still many patients who complain of dryness after wearing glasses. This situation is mostly caused by wearing soft contact lenses. The reason is that after wearing contact lenses, the tears are relatively reduced or the secretion of tears before the glasses is less. The tear evaporation increases after wearing the mirror, so a dry feeling appears. In addition, it is also related to factors such as poor wettability of the lens and a large amount of lens deposits. In addition, it is easy to produce this symptom if it is too tight (ie, the degree of fit after wearing the lens). As long as the eye drops are properly applied, the cause of the removal of the cause can be improved. Some people have dry eye symptoms and think that wearing high-water lenses can alleviate symptoms, which is wrong. Because the high water-containing lens will absorb more tears to maintain its own water balance, and at the same time the evaporation of the contact lens surface increases, it will be counterproductive and useless. The correct choice is to wear a low water content lens or RGP mirror.
Corneal ulcer, the most serious complication
Of all the complications, the most serious is corneal ulcer. However, this situation only happens occasionally. The reason is that the lens is deteriorated, the oxygen permeability is lowered, the lens is broken or the nail of the wearer is damaged, and the cornea is damaged. The lens and the lens of the care solution are contaminated. This causes corneal infectious inflammation and forms corneal ulcers. If there is eye congestion, eye pain, photophobia, tearing, and corneal whitening, you should immediately stop wearing contact lenses, go to the hospital for treatment, and actively use special antibiotic eye drops. The timing of delays will have serious consequences.
Acute infectious conjunctivitis, common complications
Among the complications of contact lenses, acute infectious conjunctivitis is more common. It is usually characterized by congestion of the eyes and secretions. It is caused by infection of pathogenic bacteria on the conjunctiva. In this case, you should immediately stop wearing contact lenses, go to the hospital for specialist treatment, and generally improve your treatment with drops of antibiotic eye drops. 1 to 2 weeks after the cure, the lens and the care box should be thoroughly cleaned and disinfected, and it is best to replace the new care solution.
Giant papillary conjunctivitis, strengthen cleaning
If the wearer has eyes that are easy to be congested, eye secretions increase and feel itchy, check for conjunctival hyperemia and large nipple hyperplasia, and the lens is prone to protein membrane precipitation, lens movement is large, appearing up or falling out, etc. The situation, it is likely that another common complication - giant papillary conjunctivitis - has occurred. This inflammation occurs because the sputum conjunctiva is allergic to denatured proteins deposited on the lens and the mechanical stimulation of the lens to the eyelids. Treatments usually use sodium citrate eye drops and eye drops that inhibit inflammation. Those with severe symptoms should stop wearing for at least two months to relieve inflammation. The precaution is to thoroughly clean the lenses daily, using the protease tablets once a week, or using disposable or rigid gas permeable contact lenses (RGP lenses).
Myopia is in life, and wearing contact lenses is a common occurrence. However, wearing invisible eyes will also have some complications. Therefore, always remember to protect your eyes while protecting your health!
