Each of us probably has a desire to maintain good vision, as it affects how we perform our daily tasks. Thus, adhering to eye hygiene is highly important. It entails limiting eye strain which can definitely cause harm, performing special eye exercises that promote well-being, and regularly visiting a doctor who can clearly explain to us vital questions, such as what is considered distance vision, when check-ups are deemed urgent, and why waiting can create an array of extra vision issues.
Remember that checking our distance vision is needed not only when we already have serious symptoms. The thing is that most symptoms can be silent for a long time.
Tables for Checking Visual Acuity
Visual acuity can be determined by using special offline optotypes charts, such as the Snellen chart. Since we usually do not have such a tool at home, we can go online. Currently, there are numerous online programs for checking both distance and near vision, some of which exist as applications for mobile phones. These programs consist of special graphical tests, which can help identify farsightedness, nearsightedness, and astigmatism with a high degree of probability.
There are also special charts that can detect more serious vision disorders, such as macular degeneration, which involves central vision impairment. Macular degeneration can be detected using an Amsler grid chart, which consists of grids with a thick dot in the center. You need to cover one eye with your hand and look at the central point with the other eye. If some lines of the grid appear wavy, there is a high probability that you have macular degeneration. The Amsler grid and numerous other self-check vision tests can be found online for home diagnostics.
Symptoms to Watch Out For
We all live in stress now, and sometimes when we are standing up too quickly, it can make our vision blur, but this is not a reason for an urgent examination. In this case, you can measure your blood pressure and consult a therapist or family doctor. However, if you notice flashes, flickering in your eyes, a spot that doesn’t disappear, you should urgently consult an eye doctor.
How often we must visit an ophthalmologist:
- Children’s check-ups from the age of 5 should be done every six months.
- From 18 to 40 years old — once a year.
- Patients over 50 years old — twice a year.
Overall, it’s individual and depends on your doctor’s recommendations.
It’s also worth considering that no distance vision tests or so-called home diagnostics can replace a professional examination. Therefore, it’s important not to disregard visiting a specialist. The thing is that 2.2 billion people worldwide have vision impairments, and at least half of them could have been prevented. This is all because patients often seek help from specialists too late.
So when you start to see worse or discomfort in your eyes arises, like dryness or a feeling of sand, do not ignore these signs.
