Reading glasses or computer glasses
Do I need them?
MODERN LIFE AND ITS EFFECTS ON OUR EYES
Many changes have occurred as a result of technological advancements, from how individuals work to how they use their free time. As people of all ages spend more and more time on computers, laptops, televisions, and cell phones, more and more people are developing digital eye strain. Sore, dry, or irritated eyes, impaired vision, eye twitching, headaches, weariness, back and neck pain, and difficulty sleeping are some of the symptoms. With the use of computer glasses, these symptoms can be lessened or eliminated entirely.
In several respects, computer glasses differ from ordinary eyeglasses or reading glasses.
Your computer screen and digital devices should be roughly 20 to 26 inches away from your eyes for maximum comfort. This is the "intermediate" vision zone, which is closer than driving ("distance") vision but further away than reading ("near") vision.
These glasses will provide clear vision at all viewing distances if you are under the age of 40 and wear prescription eyeglasses. The ciliary muscle in your eye, however, still has to work hard to concentrate on intermediate and close objects. The more time you spend staring at your computer or phone screen, the more this muscle and your eyes grow exhausted.
Bifocals can help you see clearly at a distance and up close if you're starting to develop presbyopia. However, intermediate vision (which is required for computer use and viewing your smartphone) is frequently a difficulty. For intermediate vision, progressive lenses and trifocals can help. However, they frequently lack a sufficient middle zone for comfortable computer use.
For these reasons, many people utilize computer reading glasses. However, these, too, have their limitations.
In general, computer glasses have a magnifying power of around 60% that of reading glasses. (The best magnification depends on how close you hold your digital gadgets and how far you sit from your computer screen.)
Reading glasses from the store are just magnifying lenses in a frame.
On the other hand, good computer glasses accomplish three things:
-Make any necessary corrections to your refractive errors.
-Make sure you have the right magnification for your digital gadgets.
-Blue light should be avoided at all costs.
Additionally, when utilizing your gadgets, custom computer glasses place the optical center of the lenses directly in front of your pupils. In store-bought reading glasses, this intermediate pupillary distance is not customizable.
Furthermore, most store-bought reading glasses offer little or no protection from blue light.
Custom computer glasses give you a clean, wide view of your digital gadgets, reduce focusing effort, and shield you from blue light.
Tints and coatings for lenses
Anti-reflective coating on the lenses of your computer glasses is recommended for maximum comfort. Eye strain can be caused by reflections from the front and back surfaces of eyeglass lenses. These unpleasant reflections are eliminated with an anti-reflective (AR) coating.
Another necessary for protecting your eyes from possibly dangerous high-energy blue light emitted by digital devices is a blue light filter. Those are examples of high-quality computer glasses lenses with built-in blue light filtration.
To prevent glare from overhead lights, your eye doctor may prescribe tinting the lenses of your computer glasses.
Where can I purchase computer glasses?
Avoid the temptation to acquire cheap, off-the-shelf computer reading glasses.
To rule out vision problems or update your eyeglass prescription, start with a full eye exam.
Measure how far you like to sit from your computer before booking your eye check. From the bridge of your nose to the surface of your computer screen, take a measurement.
Bring this measurement to your eye examination. It will assist your ophthalmologist in determining the appropriate lens power for your computer glasses.
