Metal desks are not widely practiced yet. They are mostly used either in cases, where conditions don’t allow to use friendlier to a man materials, or there, where the style called "techno" got accustomed. To manufacture such desks both steel with different coverings and light alloys with aluminum and titanium can be used.
Working at a desk top computer over fifty years of age with your general purpose prescription eyeglasses can be challenging on your eyes. The eye’s focusing ability is under a strain to keep the content on the screen clear. Just because you can see the computer screen clearly through the distant portion of your glasses doesn’t mean you are not taxing the eye’s focusing ability to maintain a sharp focus. Also, lifting your chin up to see through the mid portion of your progressive style lenses will have consequences on your neck and back due to poor ergonomics. The reason you are using a bifocal is to see at close reading distance clearly for extended periods of time.
Desk top computer use is usually more demanding beginning in the late forties or early fifties. Viewing through the distance portion of your eyeglasses to see just beyond the reading range to the computer screen puts a strain on your eyes by overworking the eye’s accommodative/focusing ability. The amount of lens power necessary to relieve the eyes from the stress is about half the amount of power necessary for you to read with.
