Reading Glasses
If you wear bifocals, you may find that — unless what you’re reading is in your lap — you must tip your head back all day long to use the reading zone in the bottom of the lenses. You can avoid neck discomfort by purchasing special work glasses that have the reading segment placed higher up in the lenses.
Special-design bifocals and trifocals for work-related tasks often are called occupational lenses.
If your hobbies include anything requiring intense focusing at very close distances, a separate pair of reading glasses may be helpful — perhaps with stronger lenses than you normally would use for reading.
Computer Glasses
Computer-specific eyewear gives you the best correction for these distances and helps you avoid what’s becoming known as “digital eye strain” — eye fatigue and discomfort associated with the use of computers, smartphones and other digital devices.
If you’re over age 40 and have presbyopia, general-purpose progressive lenses or bifocals usually aren’t the best choice for computer glasses. This is because these multifocal lenses don’t have a large section of the lens dedicated to the “intermediate” distance typically used for viewing computers and digital devices.
A better solution is a separate pair of computer glasses with single vision lenses specifically prescribed for this intermediate viewing distance, or specialty “office” or “computer” progressive lenses that have the largest section of the lens designed for this distance.
Driving Glasses
Driving glasses come in two categories: sunglasses designed specifically for driving and prescription eyeglasses. Sunglasses for driving feature polarized lenses that reduce glare and make it easier to see in bright sunlight.
Drivers who have been in accidents often claim that they couldn’t see the other car or a pedestrian because of glare reflecting off the road or the sun shining in their eyes. And studies have shown that glare can be a factor in automobile accidents.
Polarized sunglass lenses reduce glare and make it easier to see in bright conditions, and polarized lenses tinted specifically for driving increase contrast for sharper vision.
Prescription eyeglasses for driving should always include anti-reflective coating. This coating reduces glare from light reflecting off the front and back surfaces of your lenses and allows more light to enter your eyes for better vision when driving at night.
