Prescription lenses are an essential part of correcting various vision problems, whether you suffer from nearsightedness, farsightedness, astigmatism, or difficulty seeing near vision with age. With significant advancements in ophthalmology, numerous types of prescription lenses have emerged to suit every visual condition and offer the highest levels of comfort and clarity.
To help you choose the right lens, this guide provides a simple and clear explanation of all types of medical lenses, along with their features and usage methods. It's worth noting that the Optique website offers a wide range of high-quality medical lenses and glasses with diverse options.
What are medical lenses?
Prescription lenses are optical devices designed to correct the path of light entering the eye. When there is a problem with the focus of light on the retina, issues such as blurriness or distortion occur. This is where the lens comes in, refocusing the light correctly and giving the user clearer and more comfortable vision.
First: Types of medical lenses according to the visual problem
1. Myopia Lenses (Nearsightedness Lenses)
Nearsightedness means clear close vision versus difficulty seeing distant objects.
These lenses come in a concave (–) shape to reduce the concentration of light before it reaches the eye.
Its features:
- High clarity for long distances
- Suitable for studying and driving
- Available in different grades and high-quality materials for premium grades
2. Hyperopia Lenses
The person has difficulty seeing things up close, while distant vision is better.
The lenses are convex (+) to increase the focus of light on the retina.
Its features:
- Excellent for reading and close work
- It helps reduce eye strain.
- Suitable for children with impaired near vision development
3. Astigmatism Lenses
Astigmatism is caused by an uneven curvature of the cornea, which makes the image blurry at all distances.
It is treated using cylindrical lenses specifically designed to correct corneal astigmatism.
Its features:
- remarkably sharp clarity
- Relieving headaches caused by eye strain
- Precise correction of deviation angles
4. Presbyopia Lenses
It usually appears after the age of forty as a result of the eye's weakened ability to focus on close objects.
The most common types:
- Bifocal lenses
- Trifocal lenses
- Multifocal (progressive) lenses are the most advanced type, with no visible lines.
These lenses allow for near, medium, and far vision in a single lens.
Second: Types of lenses according to manufacturing material
1. CR-39 plastic lenses
Most common, characterized by its light weight and affordable price.
2. Polycarbonate lenses
Strong, very lightweight, and impact-resistant lenses, ideal for children and sports.
3. High Index lenses

4. Glass lenses

Third: Medical lenses with additional features and technologies
1. Anti-reflective (AR) lenses
It reduces reflections and improves visibility while driving or using a computer.
2. Blue light protection lenses (Blue Cut)
Designed to prevent eye strain caused by screens.
3. Photochromic lenses (lenses that change color depending on the lighting)
It turns dark when exposed to sunlight, and returns to transparency indoors.
4. Digital Lenses (HD Digital Lenses)
It offers higher resolution and clearer details, and is suitable for screen users.
How do you choose the right lens for you?
The choice of lens depends on several factors:
- Prescription and degree of vision
- Your lifestyle (computer – driving – studying – children)
- What type of frame do you want?
- Lens weight and material
- Your budget
It is always best to consult an optician for an accurate recommendation.
