Hello! It's great that you're reaching out to understand your vision changes, especially as you navigate through your 40s. At 47 years old, experiencing changes in your vision is quite common, and it can be attributed to several factors, including presbyopia and the progression of myopia (nearsightedness).

Firstly, let's clarify what presbyopia is. Presbyopia is a natural age-related condition that typically begins to affect people in their 40s and 50s. It occurs due to the hardening of the lens inside the eye, which makes it difficult to focus on close objects. This is why many people find themselves needing reading glasses or bifocals as they age.
In your case, you mentioned that you have myopia (nearsightedness) of -6.50 diopters, and you are noticing that your ability to see clearly at a distance is still good, but your near vision is deteriorating. This is a common scenario for individuals who are myopic. The reason your myopia might seem to worsen while also developing presbyopia is that these two conditions can coexist. While presbyopia affects your ability to see up close, myopia can continue to progress, especially if you have a history of high myopia.

It's also important to note that myopia can worsen due to various factors, including genetics, prolonged near work (like reading or using screens), and overall eye health. The misconception that myopia should decrease with age is not universally true; while some individuals may experience a stabilization or reduction in myopia, others, especially those with higher degrees of myopia, may see their prescriptions increase.

Regarding your question about the type of lenses you should consider, if you are experiencing difficulty seeing up close, you might benefit from multifocal lenses, which can correct both your distance vision and your near vision. Bifocals or progressive lenses are popular options that allow for a smooth transition between different focal lengths. It's essential to have a comprehensive eye examination to determine the best lens type for your specific needs.

As for the accuracy of vision tests at optical shops, it can vary. Many optical shops employ trained opticians who can perform refractions and provide prescriptions. However, for a more thorough evaluation, especially considering your high degree of myopia and the recent changes in your vision, it is advisable to see an eye care professional, such as an optometrist or ophthalmologist. They can conduct a comprehensive eye exam, assess your overall eye health, and provide a precise prescription tailored to your needs.

In summary, your experience of worsening near vision at 47 is likely due to the onset of presbyopia, which is common at this age, alongside the possibility of continued progression of your myopia. It’s important to consult with an eye care professional who can provide you with the best options for corrective lenses and monitor your eye health as you age. Regular eye exams are crucial to ensure that any changes in your vision are appropriately managed.
