For all the good they do, eye drops have one major drawback: it's hard to tell how much of the medication is actually getting to the eye. Now in a study, scientists report that they have developed a contact lens(隐形眼镜)that changes color as drugs are released. This visual indicator could help eye doctors and patients readily determine whether these medications are where they should be.
Eyes are good at keeping things out. When something gets into or toward an eye, the lids blink and tears start rapidly flowing to avoid infection and damage from foreign objects. These processes are usually helpful, but they can block the uptake of much-needed medications. Studies suggest that less than 5 percent of drugs in eye drops are absorbed, and much of the absorbed medication ends up in the bloodstream instead of the eye, causing side effects. Contact lenses may be a more effective way to deliver drugs directly to the eye, but real-time monitoring of drug release is still a challenge. So Dawei Deng and Zhouying Xie sought to create a drug-delivering contact lens that would change color as the medication is released into the eye.
The researchers made a color-sensitive contact lens using a technique that creates tiny holes that match the size and shape of a specific medicine. In laboratory experiments, the contact lenses were loaded with a drug used to treat a kind of eye

disease. Then, the team exposed the lenses to a solution of artificial tears, which was used as a substitute for the eye. As the drug was released from the contacts, the architecture of the molecules near the drug changed, which also changed the color in the iris(虹膜)area of the lenses. They conclude that this new lens could control and indicate the continuous release of many eye-related drugs. 22. Why did scientists develop the new contact lens?
A. To cure shortsightedness. B. To keep out the strong light. C. To protect eyes from damage. D. To indicate eye drug delivery. 23. Where do most of the eye drops go if delivered onto the eyes?
A. They are absorbed by the eyes. B. They are swallowed by patients. C. They end up in the eye bloodstreams. D. They are blocked out or washed away. 24. Why was the solution of artificial tears used in the experiment? A. For replacing the eyes. B. For indicating the changes. C. For absorbing eye drops. D. For controlling the release. 25. What's the main idea of the passage?
A. Patients with eye disease have hope to recover totally. B. Eye medicine can be improved with the help of the new lens. C. Color-changing contact lenses can improve eye disease treatment. D. Side effects of eye drops will reduce thanks to the new lens. 第二节 七选五(共5小题；每小题2分，满分10分)
