It is very practical to get off the shelf in a matter of seconds what we lack, but practicality and aesthetics can be detrimental without professional considerations. We talked to Dr. László Szalai, an ophthalmologist, about “instant” solutions with dioptric lenses that can be ordered and received at an attractive price on the Internet, ready-made reading glasses, and fashionable sunglasses available in perfume shops.
Sunglasses do not always filter
Just as Artúr Gombóc can choose from his beloved chocolates, we have at least as wide a selection of designer sunglasses, from rhinestones to colored plastic frames to metal, from blue, green, brown, and red, or yellow lenses to multicolored ones. They are available in all relevant fashion brand stores, but you can also choose anything from a few thousand forints at fairs and Chinese markets. Yet it doesn’t really matter what ophthalmic properties the outer rail covers.
Ophthalmologist Dr. László Szalai draws attention to the fact that the poor quality protective layer on the lens can do more harm than good in the case of sunglasses, and can even be especially dangerous to the eyes. From the expert’s explanation, we learn that the aperture of traditional cameras was modeled on how the eye works, meaning that when we put on dark sunglasses, the pupil dilates.
“AND WHEN EXPANDED, IT PROTECTS LESS, LETS IN MORE HARMFUL WAVES.”
– the expert shares with the readers of the Sofa, adding: “If the sunglasses do not filter them out in this case, it will all get into the eyes, it may have a carcinogenic effect, it may cause degenerative diseases.”

“Therefore, using sunglasses that do not provide proper filtration is much more harmful than not using sunglasses at all,” we learn from an ophthalmologist.
SO IF YOU CAN’T RESIST BUYING SUNGLASSES OF DUBIOUS ORIGIN, IT’S WORTH CHECKING THEM OUT AT AN OPTICAL STORE.
“While most commercially available sunglasses come in front of consumers after testing, a low-quality protective layer, for example, wears off after wiping a few paper handkerchief lenses and ceases to provide adequate protection,” the ophthalmologist explains.
What about reading glasses?
Over the age of 40, the shortening of the arms occurs, but is it also possible that our eyes are getting worse? Unfortunately, the latter is supported by several scientific facts. The phenomenon also has a name.
THIS IS PRESBYOPIA OR OLD AGE.
“As the eye ages,” Dr. László Szalai – the lenses lose their flexibility, their own focusing mechanism is weakened and they have to help the eye with close-up + diopter glasses. ”
“It’s a mistake to wait by prescribing the glasses to train your eyes that way so you don’t get comfortable. The error must be measured within the framework of a correct eye examination and efforts must be made to maintain the sharpness of the vision, ”he adds.
Can we buy it ready in the perfume shop or order it from China?
We can get many times the creative, colorful, girly, fresh, and varied frames available at home, either ready-made in certain retail chains or by choosing the right lens online, mostly from the Far East.
HOWEVER, YOUR OPHTHALMOLOGIST WILL WARN YOU ABOUT USING THEM.
Dr. László Szalai draws attention to the fact that the finished products do not take into account individual variables and biological data that are examined by an ophthalmologist or optometrist for the preparation of the lens. For example, the refractive error of the two eyes, i.e. the required diopter, may be different, which, of course, cannot be expected from a prefabricated product, as can any other asymmetry.
But offers made as a mass item, such as varying pupil distances, light sensitivities, or blue light filtering recommended for browsing a monitor, cannot account for variable biological values. Not to mention the cylindricality, which can be measured on a scale of 0 to 180 degrees for both eyes. That’s why the expert advises you to keep ready-to-order or prescription goggles as an “instant” solution when you need goggles as a fire extinguisher:
WHEN YOU ARE ON HOLIDAY, YOU MUST TEMPORARILY REPLACE THE GLASSES YOU HAVE FORGOTTEN AT HOME OR UNTIL THE ORDERED GLASSES ARE READY,
but for a long-term, lasting solution, see your ophthalmologist and make your eyepiece along with your individual values.
