Glasses incorporating hearing technology aren't an entirely new idea, but modern electronics have made the concept considerably more practical.
Some devices incorporate conventional hearing-aid components into the arms of the spectacles, while others use technologies such as directional microphones or bone conduction.
For somebody who needs both vision and hearing assistance, they can sound like an ideal two-in-one solution. But there are advantages and disadvantages worth considering.
The advantages
One device instead of two: Perhaps the most obvious benefit is convenience. Put your glasses on and your hearing assistance comes with them. This may be particularly useful for people who find handling tiny conventional hearing aids difficult because of arthritis, reduced dexterity or poor eyesight.
Less equipment around the ears: Wearing spectacles and behind-the-ear hearing aids simultaneously can sometimes feel crowded. The arms of the glasses, hearing aids and perhaps even a face mask can all compete for the same limited space.
They can be discreet: Hearing technology incorporated into spectacle frames can be less immediately noticeable than some conventional hearing aids. For people who feel self-conscious about wearing hearing aids, this might encourage them to use their hearing assistance more consistently.
Bone-conduction possibilities: Some hearing glasses transmit sound through vibrations in the skull rather than relying entirely on sound travelling through the ear canal. Bone-conduction technology can be useful for particular types of hearing loss, although it certainly isn't suitable for everybody.
Modern technology: Depending upon the model, hearing glasses may offer features such as rechargeable batteries, Bluetooth connectivity and smartphone controls.
But there are disadvantages
The biggest drawback is equally obvious: you cannot easily separate your glasses from your hearing assistance.
Take your spectacles off to clean them, change into prescription sunglasses or simply rest your eyes and you may also lose your hearing assistance. If either part of the combined device develops a fault, you could temporarily lose both.
Choice can also be more restricted. Conventional hearing aids are available in an enormous range of designs, power levels and configurations. Combining them with spectacles inevitably reduces your options, particularly when it comes to choosing frames.
There is also the question of upgrading. Your eyesight and hearing don't necessarily change at the same rate. You might need a new spectacle prescription while being perfectly happy with the hearing technology, or want newer hearing aids while your glasses remain perfectly adequate.
Cost should also be considered. Specialist hearing glasses can be relatively expensive, and repairs or replacement frames may be more complicated than taking ordinary spectacles to your local optician.
Most importantly, hearing loss varies enormously. A system that works brilliantly for one person could be completely inappropriate for another.
Are hearing glasses worth considering?
Absolutely, particularly if you already wear spectacles throughout the day and dislike managing separate hearing aids.
However, don't choose them simply because the two-in-one concept sounds convenient. Have your hearing properly assessed and discuss the different options with a qualified hearing professional or audiologist. It is also worth asking whether you can trial the technology before committing to an expensive purchase.
And remember that unexplained or sudden hearing loss, hearing loss affecting only one ear, persistent tinnitus, dizziness, pain or discharge from the ear should be medically investigated rather than simply addressed by purchasing a hearing device.
Glasses with built-in hearing assistance are unlikely to replace conventional hearing aids for everyone. But for the right person, combining clearer vision and better hearing in one familiar item could be an extremely useful solution.

Having tried spectacles with in-built hearing aids I found them to be very large and not what I would call fashionable. They are also very heavy to wear for any long period of time.
Battery use is also an issue. They need frequent re-charging. Whilst I find it irritating to have to replace the batteries in my current hearing aids every couple of days, I'm not without my hearing aids at all as I carry some spare batteries with me.
