Contact lenses are tiny, flexible lenses that are often worn on the eyes. Over half a million people worldwide have used these lenses as ocular prosthesis for more than 150 years. Since contact lenses offer a simple, practical approach for people to see better, they can be used to correct both near and distant vision. These lenses are especially made for those with presbyopia or visual impairment who must wear corrective lenses.
However, these lenses can also be worn for decorative purposes and occasionally as a fashion accessory.
When placed directly on the cornea (the front surface of the eye), contact lenses are small, transparent plastic lenses that can correct vision issues. This feature sets them apart from glasses, which are worn slightly farther from the eyes.
The Various Contact Lenses Types
These days, contact lenses come in a great range. You can select the contact lens type that best fits your needs and way of life. Let's examine the various categories of contact lenses on the market:
1. Clear Contact Lenses:
For many people who wear prescription glasses, clear contact lenses are a popular option. The brand is integrated via three lenses. Additionally, we offer daily and monthly disposal options for all of our lenses. Depending on your desire, you can choose from a variety of colours, some of which also improve peripheral vision.
Clear Monthly and Daily Contact Lenses - People who wear contact lenses are constantly looking for ways to enhance their comfort, clarity of vision, and usability. Daily disposable lenses from Aqualens are designed to be worn every day, whereas monthlies are only meant to be used for up to a month before needing to be changed out for new lenses. Each has advantages and offers something unique to the table.
2. Colour Lenses:
Colour contact lenses are designed to mimic the appearance of the iris, the coloured area of our eyes. Some colour contacts even have a series of tiny black dots and uniformly spaced red and yellow squares since the majority of this area is made up of tiny black shapes and coloured squares, which can make the lenses feel more comfortable to wear and make them appear more natural on your eye than when you wear glasses.
Shades, visibility tint, enhancement tint, and colour tint are the several categories that these different types of coloured contact lenses fall under. And underneath these three variations, we'll map the supplied colours from Aquacolor contacts to the appropriate colour.
3. Toric Lenses:
Toric lenses are curved (cylindrical) lenses that rotate to have the proper angular momentum and eye-lid interaction.
Features of toric contact lenses
- These thin contact lenses are made of both silicone hydrogel and regular hydrogel.
- They differ from conventional contact lenses, which are rectangular in shape and help correct myopia and hypermetropia.
- In order to correct the astigmatism of the eyes, toric lenses are employed.
- Just as toric lenses can correct your close vision by rerouting light to the retina, they can also correct your far vision by altering the direction of light through the eye.
- Because of their enhanced distant vision, Aqualens toric contact lenses are frequently worn in conjunction with spectacles.
4. Soft Lenses Contacts
Soft contact lenses may readily adapt to the form of your eye because they are thin and flexible. 90% of individuals who wear contacts use soft lenses, which were the first type of contact lenses to be made available in America in the 1970s after years of development. Soft contacts do an excellent job of holding onto moisture and allowing oxygen to reach the eye. They are typically regarded as the most comfy kind of contact lenses.
Soft and flexible plastics, such hydrogel, are used in the manufacture of soft contact lenses to increase the amount of oxygen that may reach the cornea. They are created using cutting-edge optical technology processes. The soft lens is more breathable as a result, which is why they are more well-liked.
Benefits:

- Long wear times are best accommodated by soft lenses. They are also the best kind of contact lenses if you want to wear them periodically and are not constrained by any specific wearing schedules.
5. Contact lenses that are rigid gas permeable (RGP)
In comparison to soft lenses, rigid gas permeable lenses (RGPs) are slightly more stiff because they are comprised of sturdy plastics. It increases their resistance to any form of deposit build-up, which gives the wearer clearer eyesight. These types of contact lenses are less comfortable than soft lenses, therefore it can take you a few weeks to become used to wearing them. Not very prevalent among contact lens users due to a more difficult adjustment curve for comfort.
Benefits:
- Such lenses endure longer since they are less likely to tear because to their sturdy construction.They are also affordable due to their lengthy lifespan.
- Since they can't bend and flex like soft contacts, rigid gas permeable contacts are considered "hard" contact lenses. Although they nevertheless allow oxygen to
- Pass through their structure, as their name suggests, so that your eyes may breathe.
- RGP lenses can provide sharper vision correction and are less likely to accumulate bothersome deposits than soft lenses. The negative? Many individuals first find them less comfortable than soft lenses since they take some time to get acclimated to.
6. Contact lenses for the sclera
Rigid gas-permeable contacts that cover the sclera (the white part of the eye) and cover a wider area of the eye. They are typically given to treat vision problems brought on by irregularities in the cornea.
7. Hybrid contact lenses
Hybrid contacts contain a stiff zone in the centre and a soft "skirt" of material surrounding it, combining the advantages of soft lenses and RGPs. With this design, you have the comfort of a soft lens with the clearer vision of an RGP lens.
Hybrid lenses are less popular since they need a very perfect fit and typically cost more than other types of contacts.
8. Contact lenses that are frequently replaced or disposable
Contact lenses that can be routinely replaced after use are referred to as disposable. There are four different types of disposable contact lenses: yearly, quarterly, monthly, and daily disposable. If the contact lenses are daily disposables, you can use them for the day and switch to a new set the next day.
Contrarily, monthly disposable contact lenses can be changed after up to 29 days of wear. For cleaning, sanitising, and storing the reusable disposable contact lenses, such as quarterly, monthly, or yearly disposable, it would be beneficial if you usedsoft contact lens care solutions.
Benefits:
- Daily disposable lenses are simple to handle because there is no need to worry about washing or sanitising them.When travelling, daily disposables are
- particularly helpful because you can easily stock up on contact lenses to get you through the trip.After cleaning them with a soft contact lens care solution, monthly, quarterly, and yearly disposable contact lenses are easily reusable.
