The end of reading glasses

Impact summary

One of our very own postgraduate research students, Devesh Mistry, is in the process of developing a new eye lens, made from the same material found in smartphone and TV screens. This could restore long-sightedness in older people. As people age, their lenses lose flexibility and elasticity. This leads to a condition known as presbyopia, common in people over 45 years old, and can require optical aids, such as reading glasses.

Devesh is now working with liquid crystal to create a truly adjustable artificial lens.

Underpinning research

Using these liquid crystal-based materials, Devesh’s research is developing synthetic replacements for the diseased lens in the eye - a new generation of lenses and intra-ocular lens implants to rejuvenate sight. Devesh is currently researching and developing the lens in the lab and aims to have a prototype ready by the end of his doctorate in 2018.

Within a decade, this research could see the new lens being implanted into eyes in a quick and straightforward surgical procedure under local anaesthetic. Eye surgeons would make an incision in the cornea and use ultrasound to break down the old lens. The liquid crystal lens would then be inserted, restoring clear vision.
