Prescription glasses, also known as prescription eyeglasses or spectacles, are eyeglasses that are customized to correct refractive errors in vision. These glasses are designed based on an individual’s specific eyeglass prescription, which is determined by an optometrist or ophthalmologist after conducting a comprehensive eye examination.

Prescription glasses are used to address common vision problems, including:

1. Myopia (nearsightedness): Difficulty seeing distant objects clearly.
2. Hyperopia (farsightedness): Difficulty seeing nearby objects clearly.
3. Astigmatism: Blurred vision caused by irregularly shaped cornea or lens.
4. Presbyopia: Age-related difficulty in focusing on nearby objects due to reduced flexibility of the eye’s lens.

The prescription for the glasses includes specific details for each eye, such as the lens power (measured in diopters), the type of lens (single vision, bifocal, or progressive), and any additional lens coatings (e.g., anti-reflective coating, photochromic, or blue light filter) based on individual needs.

Prescription glasses come in a wide variety of frame styles, colors, and materials, allowing individuals to express their personal style while also correcting their vision. It’s important to visit an eye care professional for a comprehensive eye exam and prescription to ensure you get the correct and most suitable prescription glasses for your needs.
