Complete Guide to Lens Types and Their Treatments

Choosing the ideal lens for your glasses can be a challenging task, especially with the many options available on the market. At Óticas Cachoeiro, we offer a wide range of lenses to meet the specific needs of each customer. This guide will help you understand the differences between the main types of lenses and the treatments available to ensure clear and comfortable vision, but remember: it is your ophthalmologist who should recommend the type of lens that is most suitable for you.

1. Single Vision Lenses

What are they?
Single vision lenses have a single prescription across the entire surface of the lens, which means they only correct one type of vision, whether it be distance or near.

Indication:
Ideal for those who only need to correct myopia, hyperopia or astigmatism.

2. Bifocal Lenses

What are they?
Bifocal lenses have two different prescription areas: the upper part is intended for distance vision, while the lower part is intended for near vision.

Indication:
Recommended for people with presbyopia (difficulty focusing on close objects, common after the age of 40) who still need correction for distance vision.

3. Multifocal (or Progressive) Lenses

What are they?
Multifocal lenses, also known as progressive lenses, offer a smooth transition between multiple prescriptions without the visible divisions of bifocal lenses. They correct vision at all distances: distance, intermediate and near.

Indication:
Perfect for people with presbyopia who want an aesthetic solution without visible lines.

4. High Index Lenses

What are they?
Lenses made of thinner, lighter materials, specially designed for people with high prescriptions.

Indication:
Recommended for people with high degrees of myopia or hyperopia who want lighter glasses with a thinner appearance.

5. Polarized Lenses

What are they?
Lenses that reduce glare caused by reflective surfaces such as water, snow or roads.

Indication:
Ideal for those who spend a lot of time outdoors, especially in activities such as driving, fishing or practicing water sports.

6. Lenses with Blue Light Filter

What are they?
Lenses that block or filter blue light emitted by digital screens, such as computers, smartphones and tablets.

Indication:
Recommended for people who spend long hours in front of digital screens.

Lens Treatments

In addition to choosing the type of lens, it is possible to add specific treatments to improve the functionality and comfort of the glasses:

• Anti-glare: Reduces unwanted reflections, providing clearer vision.

• Anti-scratch: Increases the durability of the lenses, protecting them against scratches.

• Photochromic: Lenses that automatically darken when exposed to sunlight, offering protection against UV rays.

• Hydrophobic and Oleophobic: Treatment that repels water, dust and grease.

Choosing the right lens depends on your visual needs and lifestyle. Consult your ophthalmologist to determine the type of lens that is best for you. At Óticas Cachoeiro , we are here to help you find the best solution, ensuring comfort, style and clear vision in all situations.
