Taking a Clear Look at Prescription Sunglasses

Losing those magnetic or clip-on sun shields for your prescription eyeglasses can be frustrating and expensive. Maybe you don’t wear sunglasses at all. However, the sun can be harmful to your eyes, and skipping protection for them altogether can be dangerous. Maybe it’s time to invest in prescription sunglasses.

Sunglasses can be made with nearly any lens prescription. Perhaps you’re yearning to drive off into the sunset, seeing clearly in the distance without squinting. Or maybe you would like to be able to read a book at the beach with bifocals. Sunglasses can be made to meet your vision needs while protecting your eyes from harmful and annoying sun rays.

Enabling communication, interaction, and life

dbGLOVE

dbGLOVE is a wearable device that digitizes several existing touch-based alphabets, such as Malossi and Braille, to enable blind and deaf-blind people to use all the features of a mobile device, to communicate with others, and to interact with the world.

Users simply type messages on dbGLOVE using the other hand.

Messages can be displayed on the screen to the normally sighted, they can be translated into speech, or they can transmitted over the Internet.

Replies are sent to dbGLOVE, which translates them into vibrations that simulate touch cues representing letters over the hand, allowing the user to read the message.

Analysis of Femtosecond Laser Assisted Capsulotomy Cutting Edges and Manual Capsulorhexis Using Environmental Scanning Electron Microscopy

Abstract

Purpose. To investigate the structure and irregularity of the capsulotomy cutting edges created by two femtosecond (FS) laser platforms in comparison with manual continuous circular capsulorhexis (CCC) using environmental scanning electron microscopy (eSEM). Methods. Ten anterior capsulotomies were obtained using two different FS laser cataract platforms (LenSx, n = 5, and Victus, n = 5). In addition, five manual CCC (n = 5) were obtained using a rhexis forceps. The specimens were imaged by eSEM (FEI Quanta 400, OR, USA). Objective metrics, which included the arithmetic mean deviation of the surface (Sa) and the root-mean-square deviation of the surface (Sq), were used to evaluate the irregularity of both the FS laser capsulotomies and the manual CCC cutting edges. Results. Several microirregularities were shown across the FS laser capsulotomy cutting edges. The edges of manually torn capsules were shown, by comparison of Sa and Sq values, to be smoother (P < 0.05) than the FS laser capsulotomy edges. Conclusions. Work is needed to understand whether the FS laser capsulotomy edge microirregularities, not seen in manual CCC, may act as focal points for the concentration of stress that would increase the risk of capsular tear during phacoemulsification as recently reported in the literature.

Pioneering First Gene Therapy Trial Opens the Door for Reversing Some Previously Incurable Forms of Blindness

Very promising first gene therapy trial opens the door for reversing some previously incurable forms

The sight of thousands of people with previously incurable forms of blindness could be saved thanks to a pioneering new gene therapy that requires just one operation.

In what scientists called a “very promising” first trial, six patients have been successfully treated for choroideremia – an inherited disease that leads to a gradual loss of sight and eventually total blindness.
