Just to share my experience…
I wear progressive readers that I buy for cheap on Amazon. They are great, and that’s all I really need. My distance vision is great, it’s only up to a meter away that I need the readers.
SO…I bought the readers at Apple, the 2.00 to 2.5 readers, since that’s what I normally wear.
For the most part, they worked well. Stuff close up was clear, but I did tend to notice that things in the distance, for example, the branches on trees in the Environments, such as in Joshua Tree and Mt. Hood…the branches looked a tiny bit blurry. At first I thought maybe that’s just the resolution that the environments come in and this is as good as it gets.
However, just before I flew home from Miami to Guatemala, I decided to do an actual eye exam. The results were a bit different than what my readers give me, so I placed an order for the prescription lenses. They just arrived today and hey! Things in the distance look better!
The moral of the story: If you wear readers and haven’t bothered to actually do an eye exam in a while, and if you notice any blurriness…you may want to get an exam and order prescription lenses.
