Forum user claims to reverse 0.75 D of myopia in eight months

Reduces 0.75 diopters in 8 months with weaker glasses and two hours of sun

According to his account, myopia can be reversed without doctors or pills. He doesn't bring a clinical trial; he brings his prescription. He went from being prescribed -4.75 and -4.50 diopters by opticians to managing with -3.75 in both eyes. That's 0.75 fewer diopters in eight months, and up to a full diopter at the best times of day. The fine print comes naturally: since summer, he detects no further pogre, and his visual acuity fluctuates depending on the time, light, and accumulated fatigue.

The story is from a person nearly 30 years old, myopic since age 11, with an initial correction around -1.5 diopters and glasses since puberty. His thesis is that excessive correction and long days in front of the computer left the ciliary muscle in permanent tension, causing the eyeball to elongate. Each visit to the optician increased his prescription by 0.25 to 0.5 diopters. Fed up, he created his own protocol: breaks every 20 minutes, good natural light, going out without glasses in familiar areas, watching birds, and reading moving license plates.

From -4.75 D to -3.75 D: the numbers of the method

The scheme is no mystery: glasses of different power according to distance. For the computer screen, he uses differential lenses of -2.25 D; for the street and night, standardized ones of -3.75 D; and he keeps other corrections (-2.00 D, -3.25 D, -3.50 D) for specific lighting conditions or distances. With the -3.5 D lenses, bought on AliExpress, he renewed his driver's license.

To verify the numbers add up, he uses the Snellen chart and a classic rule of three: if he reads small text at 24 centimeters, that equates to 100/24 = 4.16 diopters. With the differential lenses on, that same reading moves to 59 centimeters, resulting in -1.6 D plus the -2.5 D of the lens, i.e., -4.19 D. At night, with the standardized correction, he reads the 20/20 line at three meters. In the morning, with loose lenses, he reaches the screen at 75-80 centimeters. The complete breakdown of each correction and distance makes for a table that doesn't fit here.

What are differential computer glasses?

They are lenses with less power than the official prescription, designed for close work without straining the eyes. The logic is simple: someone with four negative diopters looking at a screen at 50 centimeters doesn't need full correction; half is enough. The rule used is that below two negative diopters they aren't necessary, because at that distance focus is sharp without glasses.

The theoretical framework comes from Endmyopia, the method citing Jake Steiner, whose most conservative version reserves positive lenses for the last diopter, when myopia is less than -1.00 D. The Bates method is also mentioned, with focusing and relaxation exercises. The common idea: place the blurred horizon at a distance that forces the eye to work without tensing it.

The ocular risk cited against these practices

Here consensus breaks down. Some argue that reducing eye length forcibly would leave the retina slack and increase the risk of detachment, plus possible changes in intraocular pressure. The response is that detachment is associated with high myopia, not a reduction of less than one diopter, and that axial elongation in the opposite direction poses no problem per se. Neither position offers studies to settle the discussion. Given any ocular symptom, the decision should involve a healthcare professional.

Cases claiming success

It's not an isolated testimony, although all are just that: testimonies. One claims to have gone from -3.75 to -1.75/-2 in two or three years. Another assures having dropped from -2.75 to -0.50 with eye muscle exercises, fewer glasses, and sun baths. A third says he reduced two diopters with relaxation and distant focus. And there are those who, with 1.4 diopters since 2000 and never having worn glasses, had a check-up and remained the same, with some astigmatism.

Alternative explanations also appear. One of the most repeated: part of the spontaneous improvement comes with age, because myopes tend to become slightly hypermetropic and the diopters compensate. Another points to natural light and outdoor time as the main factor, rather than exercises.

From 5 to 200 euros: the margin that causes outrage

The economic chapter heats up the tone. It is claimed that lenses cost about 5 euros and glasses end up selling for 200, and that each annual review ends in an increase in power. The accusation is heavy and launched without an audit, but connects with broad distrust towards the optical circuit. The author of the story assures that a doctor confirmed it is a bad idea to use the same correction for all distances. There is the business, he implies.

Atropine and DIMS lenses: what medicine actually studies

Against home DIY, conventional research goes another way. A randomized clinical trial in children comparing diluted atropine at 0.025% with DIMS technology lenses, designed to keep central vision sharp while generating peripheral blur to halt axial elongation, is cited. The study appears endorsed by the Spanish Agency of Medicines. That is, orthodoxy also admits that optics and environment modulate myopia pogre. Only it does so with protocols and controls.

The method, in any case, promises no miracles: its author sets the ceiling at around one diopter per year and acknowledges it has stalled. For now, it remains another testimony of partial and debatable improvement. The data available, his own, allow belief. The missing data do not.
