Vision recovery without surgery or contact lenses is a topic that garners much interest, especially among individuals seeking alternatives to traditional corrective methods. The book you mentioned, which suggests that vision can be restored through eye exercises and mental training, reflects a perspective that has been both supported and criticized within the medical community.

Firstly, it is essential to understand the underlying causes of vision impairment. Common refractive errors, such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism, are primarily due to the shape of the eye or the cornea's curvature. These conditions typically require corrective lenses or surgical intervention to achieve clear vision. While some proponents of vision training argue that specific exercises can strengthen eye muscles and improve focusing ability, scientific evidence supporting the effectiveness of these methods is limited.

The concept of "vision training" often revolves around exercises designed to enhance visual skills, such as tracking, focusing, and eye coordination. While these exercises can be beneficial for certain conditions, such as convergence insufficiency (difficulty in maintaining eye alignment when looking at nearby objects), they do not fundamentally change the eye's physical structure or correct refractive errors. For most individuals with common vision problems, the anatomical and physiological aspects of the eye are the primary determinants of visual acuity, which cannot be altered through exercises alone.

Moreover, the idea that vision can be restored through mental training is also contentious. While mental focus and relaxation techniques can help reduce eye strain and improve overall visual comfort, they do not replace the need for corrective lenses or surgery for refractive errors. The brain's ability to process visual information can be enhanced through various cognitive exercises, but this does not equate to a physical restoration of vision.

In some cases, individuals may experience improvements in their vision due to changes in lifestyle, such as reducing screen time, improving lighting conditions, or adopting a healthier diet rich in nutrients beneficial for eye health (like vitamins A, C, and E, omega-3 fatty acids, and lutein). However, these changes are more about maintaining eye health rather than reversing refractive errors.

For those with specific eye conditions, such as amblyopia (lazy eye) or strabismus (crossed eyes), vision therapy may be recommended. This therapy often involves a structured program of visual activities supervised by an eye care professional, aiming to improve visual function and coordination. However, this is distinct from the general notion of "exercises" that claim to restore vision without any professional guidance or intervention.

In conclusion, while there are various methods and philosophies regarding vision recovery without surgery or contact lenses, it is crucial to approach these claims with a critical eye. The consensus in the medical community is that while certain exercises may help with specific visual skills, they do not replace the need for corrective lenses or surgical options for refractive errors. If you are considering alternative methods for vision improvement, it is advisable to consult with an eye care professional who can provide personalized recommendations based on your specific condition and needs.
