Is -7 Eye Power Bad?
A -7 eye power indicates significant myopia (nearsightedness). While not exceptionally rare, it's considered a higher degree of myopia and carries a proportionally higher risk of certain eye problems compared to someone with less myopia.
Myopia is a refractive error where light focuses in front of the retina, causing blurry distance vision. A -7 prescription means a strong correction is needed to bring distant objects into focus. The higher the negative number (e.g., -7 compared to -2), the stronger the corrective lens required and the greater the degree of myopia.
Risks Associated with High Myopia
According to reference A, individuals with -5 and -7 eye power are at a significantly increased risk of retinal problems compared to those with normal vision. While these problems are rare, being aware of the signs and symptoms of retinal tears or detachments is crucial.
Managing High Myopia
- Regular Eye Exams: Frequent check-ups are vital to monitor retinal health and overall eye condition.
- Appropriate Eyeglasses or Contact Lenses: These correct vision and are essential for daily activities.
- Lifestyle Considerations: While exercise won't cure myopia (as noted in several references), maintaining a healthy lifestyle might contribute to overall eye health.
Addressing Specific Concerns
Several references highlight concerns about lens thickness and the possibility of procedures like LASIK. While these are valid considerations for individuals with high myopia, they should be discussed with an ophthalmologist or optometrist. A -7 prescription will likely require thicker lenses, but this is a necessary correction for clear vision. LASIK is a surgical option, but it is irreversible. Reference C mentions the possibility of ICL (implantable collamer lens), which offers a reversible alternative in certain cases.
Conclusion
High myopia, like a -7 power, increases the risk of certain eye complications, but it's not necessarily catastrophic. Regular eye exams and appropriate vision correction are crucial. Discussions regarding LASIK or other procedures should be held with an eye care professional.
