Contact lenses – personal style meets practical comfort
Contact lenses – personal style meets practical comfort
Contact lenses offer freedom, flexibility and a natural appearance without glasses. Modern lens types are designed to provide excellent comfort, precise vision and easy handling – whether you use them daily or only occasionally. However, due to the wide range on the market, it can be challenging to find the lens type that best suits your eyes, lifestyle and needs.
This article provides an overview of the most important aspects to consider before choosing contact lenses, as well as information about the different types and brands that dominate the market today.
The article presents a wide range of contact lenses representing different types, materials and price ranges. The aim is to provide an informative overview of the features and functions of modern lenses. The product information is based on publicly available descriptions from manufacturers and retailers and has been summarised to provide a clear and neutral overview.
Factors to consider when buying contact lenses
When choosing contact lenses, it is important to consider your vision needs, comfort and lifestyle. Here are some of the most important factors to keep in mind.
1. Vision correction and strength
Contact lenses are available for correcting short-sightedness, long-sightedness, astigmatism and presbyopia. It is important to have an eye examination and lens fitting with an optician to ensure the correct strength and fit.
2. Material and oxygen permeability
Modern lenses are usually made of hydrogel or silicone hydrogel. The latter allows more oxygen to reach the cornea, which increases comfort – especially during longer wear. If you are prone to dry eyes, the material can have a major impact on your wearing experience.
3. Replacement interval
You can choose between daily disposable, 14-day and monthly lenses. Daily disposables are practical and hygienic because they are thrown away after use, while monthly lenses are more economical but require daily cleaning and storage.
4. Comfort and moisture content
Comfort depends on both the material and the lens’s moisture content. Lenses with a high moisture content often feel more comfortable but can be more delicate. Some lenses have built-in moisture technologies that keep your eyes fresh all day long.
5. Lifestyle and activity level
If you play sports or lead an active life, contact lenses can offer more freedom of movement than glasses. Also consider whether you want lenses that can be worn for longer periods or if you prefer a daily replacement option.

Different types of contact lenses
There are many types of contact lenses, each with its own advantages depending on your needs and preferences.
1. Daily disposable lenses
Daily disposable lenses are ideal if you want maximum hygiene and minimal maintenance. They are worn for one day and then discarded, reducing the risk of irritation and infection. Perfect for occasional use or a busy lifestyle.
2. 14-day and monthly lenses
These lenses are worn for longer periods and require cleaning and storage in lens solution. They are more economical than daily disposables and come in many different options suitable for various vision needs and eye types.
3. Toric lenses
Toric lenses correct astigmatism and have a special shape that ensures a stable position in the eye. They are available as daily, 14-day and monthly lenses.
4. Multifocal lenses
Multifocal lenses are designed for presbyopia and provide clear vision both near and far. They are a good alternative to reading glasses and are available in several comfortable materials.
5. Coloured lenses
Coloured contact lenses allow you to change or enhance your eye colour – with or without prescription. They can be used both for everyday wear and special occasions, but should always be chosen based on quality and safety.

Frequently asked questions
How do I choose the right contact lenses?
Start with an eye examination and lens fitting at an optician. There, both the prescription, eye shape and tear film are assessed to ensure you get lenses that fit your eyes and needs perfectly.
Can I sleep with contact lenses in?
Only certain lenses are approved for extended wear. Most lenses should be removed every evening to allow your eyes to rest. Always follow the manufacturer’s and optician’s instructions.
How do I clean my lenses?
If you use reusable lenses, they should be cleaned daily with lens solution and stored in a clean lens case. Never use water or saliva, as this can cause infections.
What should I do if my eyes feel dry?
Dryness can be caused by the environment, screen work or lens material. Try moisturising eye drops designed for use with contact lenses, or talk to your optician about a different lens material.
How often should I have my eyes checked?
It is recommended to have your vision and lens fitting checked at least once a year. Regular check-ups ensure that your lenses still fit well and do not strain your eyes.
