Meditation may be helpful in treating glaucoma, a new study suggests.

The research found that a short course of mindfulness-based stress reduction by meditation reduced intraocular pressure, normalized stress biomarkers and positively modified gene expression in patients with primary-open angle glaucoma, the American Optometric Association reports.

The research was published in the Journal of Glaucoma. It suggests a possible role for meditation as an adjunctive clinical therapy.

The findings “provide tantalizing insight about a therapeutic option that may accompany tried-and-true pharmaceuticals, as well as hint at the role stress may play in glaucoma,” according to AOA.

Researchers “hope this latest study can validate another option for helping prevent irreversible optic nerve head damage.”

For the study, researchers enrolled 90 primary-open angle glaucoma patients and directed a study group to 21 days of daily, hour-long mindfulness meditation under the supervision of a certified meditation teacher.

The researchers said future studies should address how long the changes last and whether mindfulness meditation helps visual field function over time.

Safilo and Aquafil Econyl eyewear

Safilo has introduced Econyl regenerated nylon in its eyewear collections in partnership with Aquafil.

Econyl is a regenerated nylon obtained through the regeneration and purification process of plastic waste, such as fishing nets, old carpets and fabric scraps. Econyl, obtained through a process of depolymerization and re-polymerization, “performs exactly the same as brand new nylon and it can be recycled, recreated and remoulded again and again, with no loss of quality,” according to a press release from the companies.

“The choice of this material, never before used in the mass production of eyewear, is a tangible sign of Safilo’s further progression in its sustainability strategy and its commitment to bring innovation to a consolidated industry,” according to the release.

“Our investment to using recycled materials highlights our continued efforts towards promoting a responsible business,” said Angelo Trocchia, CEO of Safilo Group. “This sustainable material will allow us to make our contribution and create products without using new resources. Our intention is to expand the use of ECONYL as much as possible in order to decrease our carbon footprint.”

Giulio Bonazzi, Aquafil’s CEO, said: “Safilo has a long history of creating high-quality eyewear products, and we are happy to partner with such a strong player in the eyewear industry. It is a completely new sector in which our ECONYL material is now used, and it is this pioneering spirit that most unites us with a company like Safilo, which, like us, has innovation in its DNA.”

The new Tommy Jeans eyewear collection, recently launched by Tommy Hilfiger, one of the licensed brands in Safilo’s portfolio, is the first that features styles made of Econyl regenerated nylon. Safilo will progressively introduce this material also in its other brands’ collections, according to the release.

Giovanni Vitaloni, president of Mido, said on a press release:

We took this decision out of respect for the current alarming situation and for our exhibitors and visitors. As this health crisis is developing in Italy, we could not but choose to postpone MIDO’s 2020 edition. We immediately defined and selected a timeframe within the year which could meet the needs of the eyewear industry at a national and international level.

We are aware that this decision will require industry professionals, exhibitors, buyers, press members, opticians and everyone working for MIDO, including our staff, to re-schedule their attendance, with a significant impact on all internal organizations.

It will be a twofold effort as we are just a week away from the show, but we cannot honestly think of celebrating our 50 years when the world — and our country now in particular — is experiencing such an international crisis.

We trust though that, for the very nature of the current situation, which is alarming and continuously evolving, our exhibitors and visitors, the media and everyone involved will understand our decision.

Our sense of responsibility as business people, but most of all as human beings, towards our families, our children, our colleagues, has compelled us to do something that we would have never wanted to do, especially for this special edition, the year of our 50th birthday.

The new dates of MIDO 2020 will be announced in the upcoming days in order to let exhibitors reschedule their presence at the show, in compliance with possible new instruction from the relevant authorities who are dealing with this health crisis and in accordance with how the situation will develop and the availability of the spaces at Rho Fiera Milano, with which we keep constantly in touch.

This Smart Contact Lens Changes Colors If You Have Certain Eye Problems

It could be a boon for point-of-care diagnosis.

A research group in China has developed a “smart” contact lens that can show real-time changes in moisture and pressure by changing colors. The lens can potentially be used for point-of-care diagnosis of xerophthalmia and high intraocular pressure disease, according to a press release.

Early diagnosis is important for avoiding severe eye problems such as exophthalmia, which causes relatively mild symptoms, and glaucoma, which may lead to loss of vision. Such diagnoses depend on “facile and reliable monitoring of several features with significant pathologic relevance, such as the amount of tears and intraocular pressure,” notes the release from the Chinese Academy of Sciences.

However, current methods “usually require complex procedures and instruments operated by professionals, causing difficulties for point-of-care ophthalmic health monitoring.”

The “smart” contact lens “features periodic nanostructures within the poly(2-hydroxyethyl methacrylate) (pHEMA) hydrogel matrix, resulting in bright, tunable structural colors ranging from red to green to blue,” according to the release.

This structurally colored contact lens sensor is made solely from a biocompatible hydrogel, without the addition of any chemical pigments, “thus exhibiting superior biosafety and comfort for wearable applications.”

“Importantly, the spacing of periodic nanostructures within the pHEMA hydrogel are sensitive to changes in moisture and pressure, leading to real-time color changes in the ‘smart’ contact lens,” according to the release.

“Based on these features, the ‘smart’ contact lens was explored as a means for monitoring xerophthalmia and high intraocular pressure disease. In normal eye-simulation conditions, its color will not change over time; while its color changes from red to blue in the xerophthalmia-simulation condition in about 25 minutes,” said Zhao Qilong, first author of the study.

The work was led by Professor Du Xuemin from the Shenzhen Institutes of Advanced Technology of the Chinese Academy of Sciences.

“This study provides a novel and smart wearable device for timely and facile warning of the risks of xerophthalmia and high intraocular pressure disease. It will also inspire the design of a new generation of wearable devices with colorimetric sensing capabilities for real-time POC monitoring of various human body signs and diseases,” said Du.

The results were published in Journal of Materials Chemistry B.
