求助：眼睛和鼻子有什么关系
我从小就得鼻炎，经常流鼻涕，鼻子两侧经常肿起来，初中时突然左眼感觉不舒服，一觉醒来竟然成了双眼皮（本人是单眼皮），呵呵，不过等鼻炎稍微好些时又会变回去，时间长了，就一直成双眼皮了，不仅看着不舒服，而且眼睛感觉很难受，经常有迎风泪的感觉，高中做了两次激光，感觉鼻炎几乎根治了，不流鼻涕了，呼吸也顺畅，嗅觉也很好，但是眼睛却恢复不回去了，非常郁闷，请问是什么原因导致眼睛不舒服呢？谢谢 奇怪的事情啊 ，同情 好像好多人都有鼻炎。。。表示安慰。。。 谢谢大家，请问有哪个高手指点一下？ Study Finds Eyes "On The Nose", AustraliaMain Category: Ear, Nose and Throat News

A Queensland University of Technology researcher has found that our eyes may be to blame for the higher than average rates of skin cancers found on our nose.
Dr Benjamin Birt, who recently completed his PhD with QUT's Faculty of Science, found that high rates of basal cell carcinoma skin cancers on the sides of the nose could be due to ultraviolet (UV) radiation rays reflected off the eye.
"All surfaces reflect a certain amount of radiation, our eyes are no different," he said.
Dr Birt said the incidence of basal cell carcinoma (BCC), the most commonly occurring skin cancer in sub-tropical climates, was significantly higher on the side of the nose than other parts of the face and neck which were more directly exposed to sunlight.
"This could be explained by reflected radiation," he said.
In order to study the reflection of UV rays off the eye, Dr Birt made a cast of the front surface of his own eyeball.
He said this shape was then scanned into a model for a ray tracing computer program which simulated rays reflecting off the eye from a range of sun angles.
"I discovered that the curved shape of the eye created a focussing effect, producing UV hot spots on the side of the nose," he said.
"It is a possible explanation as to the high rates of skin cancers found on the nose."
Dr Birt said the reflected rays hit predominately between the tear duct and the bridge of the nose.
"The next step is to study a much greater range of facial shapes and radiation angles than possible with the existing model," he said.
"I also hope the findings will be picked up by medical researchers so a population study can be undertaken."
In 2000-2001, Australians spent $264 million on treating non-melanoma skin cancers such as BCCs and more than 364,000 new cases were recorded in 2001.
Dr Birt said one way of protecting the nose was to cover the eyes with sunglasses.
"But sunglasses may be a friend or foe to your nose, depending on how well they are designed," he said.
"Good wraparound sunglasses reduce the amount of UV radiation reaching the eye from all angles.
"Non-wraparound sunglasses will block the UV entering the eye but due to more comfortable light levels the eyelids are open wide, thus allowing radiation entering the around the sides of the sunglasses to be reflected off the eyes on to the side of the nose."
Dr Birt will take up a post-doctorate position at the National Research Council, Canada, in January 2008. 这篇帖子的意思就是说鼻侧的基底细胞癌是由于角膜的反射作用，而使其发病率较面部的其他部位的高。
