When they fit well, eyeglasses will sit securely on the bridge of the nose without pinching it. Also, the frame should not press into the face at any point and should stay secure when the person moves.
If you have never had bi, tri, or progressive lenses in your glasses, they may take a little getting used to, especially when walking the first time you wear them. However, once you figure out how they work, you will wonder how you ever got along without them.
Think all eyeglass cases work the same? Think again! Using a soft case or one that's too small for your frames can cause as much damage as leaving them unprotected.
What causes farsightedness? Clear vision occurs when light passes through the cornea and focuses precisely on the retina. Farsightedness occurs when the light focuses behind rather than on the retina.
When your child’s grades suddenly begin to plummet, and his or her teacher tells you he or she isn't engaged during class, you may be surprised to realize it could be more about your child’s vision than his or her attitude. Let’s talk about how quickly we can get your child in for a check-up.
Around 25% of the entire world population depend on eyeglasses or contacts, which highlights the importance of opticians, whose specialty is eyeglass fitting and adjustment. Opticians serve millions of people each year.
While John McAllister, Sr., a native of Scotland, opened the first optical shop in Philadelphia, it was Benjamin Franklin who patented the first pair of bifocal lenses.
A lens' ability to bend light is referred to as its refractive index. The higher the refractive index, the thinner the lens can be. Polycarbonate lenses tend to have a higher refractive index than glass or plastic.
Made of quartz set into bone, leather, or metal, the first eyeglasses made their appearance back in 1285-1289! Since frame templates hadn't been invented, ribbon was sometimes used, though with limited success.
While it’s true that many vision problems are related to advanced aging, that doesn’t mean your child can skip his or her eye exams. Some eye issues can impact your child’s ability to see at a distance, hindering his or her academic progress.
All babies are born colorblind, but don’t worry. By the time we grow up, our eyes will be able to detect 10 million different colors. It is a skill so subtle that we can even distinguish between 500 shades of gray.
The first glasses were made for reading and appeared in Italy around 1260 CE. The one drawback to these prescription eyeglasses is that they didn't have arms to they would keep falling down your nose.
Convex lenses correct farsightedness, improving vision for objects that are close up. Concave lenses are for those with nearsightedness, as they improve vision for objects that are far away.
Do you ever feel like getting new glasses is a total waste of money because they never seem to correct your vision the way you were told they would? The issue may be the optician you’re working with. When you’re ready to finally see what the right prescription is supposed to do for your vision, we’re here for you.
Do you see objects from a distance much more clearly than objects that are close? That could indicate that you have farsightedness, also known as "hyperopia." This occurs when the eye, or the lens or cornea in the eye, is shorter than normal. About 5 percent to 10 percent of Americans have hyperopia, according to the National Eye Institute.
The basic theories of vision were laid down in 1021, but it took around 200 years for those to be made into eyeglasses. The Arabic “Book of Optics” first had to be translated into Latin in the 1100s, leading to the first eyeglasses in the 1200s in Italy.
Reading or staring at a computer screen reduces the times you naturally blink. Blinking is how your eyes clear foreign matter as well as providing natural lubrication.
Before the invention of eyeglasses, people relied on handheld magnifying glasses or special reading stones to make printed material easier to see. Dome-shaped reading stones acted as magnifiers when placed directly on a printed page.
The first pair of eyeglasses is believed to have been produced in the late 1200s in Italy. These magnifying lenses were set in bone, leather or metal mountings with handles that could balance on the bridge of the nose.
Did you know that there are unique forms of eyeglasses that have only one lens, or no ear supports, and were worn in front of one eye when used? Popular examples were the pince-nez and the monocle.
The three types of pince-nez were hard bridge, C-bridge, and spring bridge, all of which held the nose differently. They reached their peak in popularity around 1880 to 1900 and were only popular with the elderly by the late 1930s.
Does it ever seem as though your vision never changes between your eye exams? While you may be lucky enough to avoid the need for corrective lenses as the years go on, it’s still a good idea to see us regularly to ensure there are no issues with your eyes that haven’t shown symptoms yet.
