Many people choose to wear contact lenses not only to pursue natural, unframeworked visual experiences, but also to provide perfect solutions for sports, outdoor activities, etc. Its derivatives, “pupils”, have become a fashion item in the eyes of many because of their ability to make their eyes more bright and divine. However, contact lenses are good, but if they are not properly worn, they also give rise to “big trouble”。
She's been wearing it too long
The presence of corrosive pigments in allergie contact lenses can give rise to corrosive effects, long-term exposure to eyeballs may lead to allergies, as well as irritation and inflammation of the cornea, conjunction. Most of the small brands are directly chromosomed on the face of the lens, and if production does not go off, there may be future cases of color matter falling off and damage to the eye。
Smaller optical zones, where pupils use smaller optical zones in pursuit of colour exaggerating effects, reduce the visibility of eye visions. The coloured part of the lens is generally less luminous, so when it's worn, it feels smaller. Especially in the darker environment, the pupils are supposed to be scattered, but because of the veil of the chromosome, there is a feeling of “basketing in the tube”, a state of “unmanned” that poses a safety hazard to driving and moving. It is recommended that the selection take into account the larger lenses of the optical area。
Some pupils have low water content, low oxygen permeability, and long wear lead to hypoxia in the corneas, resulting in red eyes and eye discomfort and affecting the health of the corneas。
What's the choice
Contact lenses are distinguished by the replacement cycle and generally fall into two categories. The first category, referred to as “traditional lenses”, refers to replacement cycles of more than three months, including quarterly and semi-annual. The second category, referred to as “short-cycle discard lenses”, refers to replacement cycles of less than three months, including monthly, two-week and day throws. In general terms, contact lenses with a replacement cycle of less than three months can only be called “discarded”。
What's good for traditional old-age and abandoned? For example, traditional and abandoned forms are like handkerchiefs and one-time wet towels. The handkerchief is dirty and can be washed for a long time; it can only be used once. But even if you can't wash your handkerchiefs, there'll be persistent stains that can't be washed, and the moist towels can only be used once, but they'll give you a good experience. While this example is not 100 per cent appropriate, the rationale is the same. While traditional annual parabolic lenses can be used for one year, in so many days, even if they are better cared for every day, there will inevitably be an impurity of protein deposition; abandoned lenses, although used for short periods, can give you the best experience of almost every day in this short period。
Another area of focus is the monthly spending, which is often the shorter the cycle of abandonment and the higher the monthly spending, so the daily monthly spending must be the highest, two weeks the second, months the next, and the lowest traditional。
