Inexpensive high quality lenses have been developed by researchers by hanging and curing droplets of a gel-like material. These lenses will cost less than a penny a piece.
Steve Lee, from the Research School of Engineering at Australian National University (ANU), said that what he was really thrilled about the fact that it will open up the lens fabrication technology.
Tips for Contact Lens Wearers
A contact lens is a thin plastic disc shaped lens placed on the eye surface to ensure clear and better eye vision. Here are some useful do's and don'ts for contact lens wearers.

Lee systematically tuned the curvature that was formed by a simple droplet with the help of gravity, and without any molds.
The high quality lens needs an oven, a microscope glass slide and a common, gel-like silicone polymer called polydimethylsiloxane (PDMS) where a small amount of PDMS is dropped onto the slide and is then baked at 70 degrees Celsius to harden it, that will create a base.

Eye infection is a common problem that often causes pain and discomfort to the eyes. Common symptoms of eye infection include pain, redness of eye or eyelids, eye discharge.
The researchers have made lenses about a few millimeters thick with a magnification power of 160 times and a resolution of about 4 microns (millionths of a meter) and they have also built a lens attachment that turns a smartphone camera into a dermascope, a tool to diagnose skin diseases like melanoma and they can also be used in a 3D print attachment.
Lee said that that the lenses could be used in the lab as implantable lenses, which the biologists could use to study cells in vivo and the high cost of conventional lenses usually discouraged the scientists from implanting them into mice.
The study was published in journal Biomedical Optics Express.

Eye Pain Symptom Evaluation
Eye pain usually follows trauma, eye infection or inflammation of the eye and the surrounding structures. The cause of eye pain can be diagnosed based on the type of pain and associated symptoms.
