Test to break rumors being grilled hot days stuck contact lens eye

Hot days, to a certain extent, it is easy to roast stuck contact lens on the eye. So sensational to say, in the end is true or false?
Experiment 1: high-temperature exposure
Time: noon
Location: open area of the cement steps
Weather Conditions: Clear
Outdoor temperature is 31 degrees Celsius, the surface temperature of 33-34 degrees Celsius. Reporters will be a particular brand of soft contact lenses on the stone steps colorless exposure, three hours after the water dries up lens distortion, curling edge of the lens to the center, but did not appear the phenomenon of melting, the exposure had put contact lenses into care solution, three minutes later, the lens recovered intact.
Results: Contact lenses after sun exposure produces serious distortion. Jilin Packaging Association, said that the current regular hard and soft contact lenses have the points, correspondent experimental material used in soft contact lenses is not an ordinary plastic, but a strong hydrophilic polymers, it melting point is generally about 160 ℃, can be sterilized physiological saline into the boiling.
Related parties: general contact lens material is a hydrogel or silicone hydrogel, the polymer is certainly its temperature capability than 100 CC.
Some netizens said that a friend wearing US-pupil distance to eat barbecue too close to the stove, glasses of Changchun, one of the leading cause of blindness ...... many years engaged in professional optician said that this information may be a hoax. Because when there is splashing into the eyes of Mars, due to the lens moisture, coupled with eye tear secretion, Mars will instantly exterminate.
Experiment 2: Fire baking
Time: morning
Location: Reporters Office
Reporter with glasses clamp onto a brand color soft contact lenses, we all know this different from glasses lens like M0032 Samstag owned, slowly approaching the lighter ignited the flame of about 10 cm above the stand. After 10 seconds, the lens becomes very hard, and no signs of melting, a minute later bake the lens, not observed signs of melting. Results: Contacts baked by fire did not melt. Hospital doctors said that a career in medicine for many years, has not met due to high temperature melting on contact lenses eye injury cases.
Doctor: professional point of view, it is unlikely, because the polymer itself is a form of contact lenses, then its high melting point, the fire burned directly to the contact lenses above, may people have a self-safe protection, Also the temperature is so high, if we can contact lenses to melt, then the man's eyelids, ah, ah skin, and even the body may all burn.
