Not anybody has clear vision. Many people need spectacles, contact lenses, or other corrective procedures to help with their far or close up vision.
When a md writes a prescription to correct vision, it includes a number for each middle. Each number is broken down further into the SPH and CYL.
When you await at your prescription, the important matter to know is the bigger the number, the stronger the prescription, and the worse your eyesight.
A 1.25 eye prescription refers to the power of the lens used to right the problem. It can have a plus sign or minus sign preceding it depending on the needed vision correction.
Notwithstanding, the plus or minus does not signal adept vision versus bad vision. (+) ways you're farsighted. (-) ways you're nearsighted.
It'southward the actual number, every bit opposed to the plus or minus, indicating the degree of vision correction needed.
Eye doctors use diopters to measure prism ability or focal length in the correct eye (oculus dexter) and left eye (oculus sinister).
They then use that measurement to decide lens power and provide an eyeglass prescription.
Additionally, prescriptions include prism measurements, which are abbreviated for base up, base downward, base of operations in, or base out.
Is 1.25 Heart Prescription Bad?
1.25 ability lens correction is relatively mild. When it comes to cosmetic vision wear, the further from zero the number, the worse a person'south sight.
For many, i.25 would not warrant prescription eyewear. Many people with 1.25 vision might cull to wear only over-the-counter "reader" glasses to better their vision.

At that place are several different kinds of refractive errors, including:
- Astigmatism occurs when the eye's cornea is misshapen
- Nearsightedness or myopia occurs when middle optics are also powerful
- Farsightedness or hyperopia occurs when the eye optics are not powerful enough
- Presbyopia occurs with failing lens flexibility due to age
Long-Term Risks of Bad Eyesight
Eye health issues are important at any age, simply most people experience a decline in vision as they grow older.
Over time, visual acuity declines. This is why we must make heart intendance and visits to the eye dr. or optician a priority throughout our lives, even with salubrious vision.
Some of the about common age-related, long-term risks include:
Presbyopia
Declining lens flexibility (eyes struggle to focus when switching from looking at objects near and far)
Floaters

Tearing
Eye sensitivity increases with age, and many people experience eye watering or tearing when exposed to air current, light, or temperature changes. It tin as well be a symptom of an infection or a blocked tear duct
Dryness
Older tear glands don't lubricate besides as they do when nosotros're younger. Keeping eyes moist as we historic period prevents itching, called-for, and potential loss of vision
More serious eye health issues that develop as you age include:
- Cataracts
- Glaucoma
- Retinal disorders
- Corneal diseases
- Eyelid bug
- Temporal arteritis
Summary
A person with "bad" eyesight couldn't clearly come across without glasses. This is unremarkably caused by refractive errors. An annual eye exam is recommended to ensure good for you vision and avert the long-term risks of bad eyesight.

These are glasses that offer a shine transition between different focal lengths. They are worn by people in need of vision correction at all distances.
LASIK
A corrective laser surgery for the eyes. Modern-24-hour interval laser treatment has the power to right vision issues up to +6.00 diopters of hyperopia, astigmatism upwards to 6 diopters, and nearsightedness up to -12.00 diopters.
PRK
Short for photorefractive keratectomy, PRK is refractive surgery. Similar LASIK, it uses a laser to treat vision issues. It's specially beneficial for people with dry out optics or thin corneas.
Speak to your optometrist for additional data about correcting or improving imperfect vision.
