I have been trying to find a solution to this problem for exactly a year now. I bought a MacBook Pro (Retina, 13-inch, Early 2015) and after using it for 2 months, I found that I stopped seeing into the distance. Previously, my eyesight was always excellent, I never complained and saw those things that people said "how could you see that?". Having an excellent MacBook Pro working machine, I stopped seeing anything at a distance of 10 meters. The faces of passers-by, buildings, road signs and so on - everything became blurry, there was a constant desire to squint to see something. The light signs of the advertising structures began to blur into several silhouettes. It feels terrible! Until the last moment, I couldn't believe it was from a new laptop. There are practically no such reviews on the Internet. Contacting Apple support service only leads to disappointment - template answers like "eye exercises-decrease in brightness-change in color profile-decrease in computer time" and nothing more. Empirically, having abandoned the MacBook Pro for several weeks and moved to work for an old laptop without Retina and not Apple, I found out that the reason for the deterioration of vision was really in the MacBook Pro Retina, since during this time my eyes told me "thank you!" and we started to see how great it used to be! Hoping for a miracle, I sat down at the MacBook Pro again, but alas - the situation returned to the past again, looking into the distance became a torment! Without stopping using the poppy, I turned to an ophthalmologist. The diagnosis is a spasm of accommodation. I quote from a scientific article: "Accommodation is the ability of the eye to see well at various distances (both far and near). When looking into the distance, the ciliary muscle is relaxed, the lens is flatter, thanks to this, the eye clearly sees objects in the distance. When looking at objects up close, reading or any other work at close range, the ciliary muscle contracts, and the shape of the lens becomes convex, this allows the eye to see well up close." The doctor prescribed drops that relieve spasm and "oh, miracle!" - vision became good again. BUT. Until after applying the drops you sit at the MacBook again. The conclusion that I made for myself is a spasm from the Retina display. The solution, the only solution that could be found, was an external ordinary monitor from a third-party company.

What to do next is not clear. The MacBook Pro was purchased with the expectation of mobility and power in the field, and as a result, you have to sit at the table all day and not leave the external monitor anywhere so as not to spoil your eyes.
