Lenses Lab spectacle lens specialist Rūta Šiaulytė answered how to do it on the news portal tv3.lt.
When is it time to visit a specialist?
The interlocutor warns you that you should worry about the state of your eyes if you have to squint to see things in the distance or read something up close. Also, he said, poor vision at dusk should be a cause for concern.
These may be the first signs that it is time to visit a specialist and see if you do not need to wear glasses or replace existing ones that are no longer suitable for you.
“If a person already wears glasses, it is time to see an optometrist, he will update the glasses prescription. If a person did not have glasses before, it would be better to register with an ophthalmologist for a complete eye exam and selection of the first glasses” , says R. Šiaulytė.
Avoid wearing glasses
The specialist points out that people often swear to wear glasses because they believe that this will worsen their vision. According to R. Šiaulytė, this is a very wrong approach:
“I’d like to forever dispel the myth that when glasses are worn, the eyes are supposed to ‘work’ less. If the eyes do not receive the necessary reinforcement, they only experience additional stress, and there is still no way to cure refractive errors in this way, on the contrary, the problem can only get worse. One can simply make life easier for oneself by seeing perfectly, so why not do it?
A visit to an ophthalmologist or optometrist’s office not only provides an individual prescription for glasses, but also provides basic recommendations on which spectacle lenses would be best suited.
Types and purpose of spectacle lenses
According to Rūta, the most common spectacle lenses are single vision. This means that there is the same refractive power on the entire surface of the lens, that is, the same diopter intensity dominates. The main reasons for wearing such glasses are myopia and hyperopia.
Another common refractive error, according to the specialist, is astigmatism, which is corrected with cylinder monocular lenses. This eye defect results in distorted or blurred vision at various distances.
The specialist points out that almost always people over 40 need glasses, as vision begins to deteriorate over the years.
“Either way, almost everyone in 40 needs or will need glasses. It’s a natural and inevitable process related to human age, also called presbyopia.
So, of course, reading glasses save, ”says R. Šiaulytė, adding that a person faces greater inconveniences when they were myopic before presbyopia.
“So a person gets tired of two glasses, constantly searches and can’t find his reading glasses, he changes them, he doesn’t have time to react to rapidly changing situations. However, today we already have a modern opportunity to comfortably solve this with progressive glasses.
The special lens design has a gradually changing diopter transition, ensuring smooth viewing at all distances: far, near, and intermediate. Visually, such lenses are no different from conventional single-focus lenses. “
Sunglasses with diopters
The specialist says that all these mentioned glasses lenses can also be applied to sunglasses. And in order not to have to wear two glasses, you can opt for photochromic spectacle lenses. They react to ultraviolet rays and light; depending on their intensity, they darken or lighten.
“Glasses with this type of lens look like normal sunglasses outdoors and indoors like corrective glasses with clear lenses. Thanks to fast technology, lenses for photochromic glasses now look completely different than they did a few years ago, so they can be not only very comfortable, but also a stylish option, ”she says.
It also highlights fast-growing glasses designed specifically for drivers.
“It’s a way to ensure a comfortable ride regardless of the weather or dazzling headlights – it maximizes visibility when driving at dusk, at night, in fog, in heavy rain or in bright sunlight.
It also significantly reduces excess light and distracting reflections, so even at dusk a more comfortable vision is ensured ”, says the specialist.
Smart glasses and devices
It is no secret that one of the greatest enemies of our eyes is smart devices. The spectacle lens specialist points out that when you look at digital displays that emit blue light for a long time, you may experience eye fatigue, they can dry out and become more sensitive to light. Sleep disturbances and headaches can also occur.
Therefore, according to her, when using a phone or working on a computer for a long time, blue light-blocking glasses with special lenses should be worn to filter the blue light and prevent large amounts of it from reaching the cornea of the patient. eye. However, the specialist reveals that there are different opinions about this type of glasses:
“Opinions on them are not unequivocal, probably because long-term damage to the eyes from blue rays has not yet been studied enough, we have yet to await the conclusions of these long-term studies. In short, screens are still in human life for a short time.
But one thing is clear: blue light accelerates eye fatigue, causes tension and dry eyes, and it is glasses that block blue light that can help prevent these symptoms. “
How to wear a protective mask to prevent glasses?
Recently, one of the most common problems faced by people who wear glasses is that the glasses get soaked when wearing a protective mask. What to do in this case? According to R. Šiaulytė, you can find various tools to solve this problem in optical stores, but he advises trying some tricks that will help avoid this unpleasant sensation.
“First of all, you have to make sure that the mask is really ideal. Pull the strings, maybe the mask is fastened too loosely? Then you just need to tie a little thread and the mask will adapt much better to the face and you will not miss the exhaled air in the glasses. This is the main purpose: to prevent exhaled hot air from passing through the top of the mask.
Mass-produced masks typically have a nose clip, but if using a home-sewn mask, an attempt should be made to fit a flexible part, such as a bent clip, to help press the mask against the back of the nose and avoid hot air. entering the glasses of the glasses.
It may not yet be possible to press the back of the nose into place, and some still have cheek gaps near the nose. Then you can try a way to seal the upper part of the mask with a medical patch ”, advises the specialist.
And if these methods don’t help you and the glasses still spray, R. Šiaulytė shares another tip on how to avoid this problem without any additional measures:
“A quick way to get rid of dew without tweezers or patches: just lower the glasses nose down, of course, if the vision doesn’t hurt. This will tighten the mask or make it easier for the exhaled air to pass through the tops of the glasses instead of circulating across the surface of the glasses. “
Proper eyewear care
When choosing glasses, it is important to ensure that the lenses of the glasses are of high quality, with a durable anti-reflective coating, resistant to scratches and dirt, says the specialist. These coated glasses will last much longer. Another important thing to pay attention to so that glasses not only provide clear vision, but also last as long as possible, is their proper care.
“And the spectacle wearer himself, by properly caring for, cleaning and storing his spectacles, will make a significant contribution to their long useful life. If the lens surface of the glasses is scratched or cracked, at first the person will not like the image and it will irritate it, additional eye strain will occur, the balance of the eye muscles will be affected, and eventually the pain head will start to bother.
It would seem obvious, but certainly not all spectacle wearers use a spectacle case, taking off the glasses not only helps them anywhere, but with the lenses down as well. This can damage and scratch the lens coating. In addition, he unknowingly steps on, sits down or places another object on the glasses, ”says R. Šiaulytė, adding that the frames of the glasses must also be treated with care.
“The unaltered shape of the glasses frames will last longer if the glasses are put on and taken off with both hands. It is also important not to keep the glasses on your head, as this will deform the glasses frame in the long run. “
Probably the most common action that people who wear glasses take is cleaning the glasses. However, according to the specialist, although this action probably seems basic and simple to many, it is also necessary to be able to perform it correctly:
“The lenses of the glasses should only be cleaned with a special cloth for glasses, clean and soft, avoiding with a paper towel, towel or any rough cloth.”
Everyone should watch their eyes
R. Šiaulytė points out that although vision problems are often caused by age-related eye diseases, this does not mean that we do not have to take care of our vision at an earlier age.
“With each passing year, we must plan more and more carefully to visit an eye care specialist and pay attention to the health of our eyes, not ignore the changes in vision that have occurred.
So I want everyone to appreciate this important feeling: the view. It opens a window to the world, it allows us to see the smiles of our loved ones, so let’s take care of our eyes, take care of them ”, says the specialist.
