As per the statistics, 61% of the world’s population wears glasses. Glasses are used as a means to adjust and rectify the vision issues that a person might be facing. Besides glasses, contact lenses are available as a way of rectifying your vision. The option to choose between these two lies with you.
Depending upon their preference and comfortability, people either purchase glasses or contact lenses. While glasses are easy to wear and work with, contact lenses are good for concealment. Many people across the world don’t like the way glasses look on them. This is one of the main reasons why they choose contact lenses.
Others think that contact lenses are complex to wear and may cause irritation to the eye. The simplicity of glasses is what pursues them to purchase it. The opinions vary from a person to the other. You cannot decide which one is more effective or better than the other. They both have the same job after all.
Contact lenses are used for rectifying conditions like Myopia, Hyperopia, Astigmatism, and Presbyopia. There are different types of contact lenses available based on the condition that you have. Some of them are as listed below;
- Soft Contact Lenses
- Rigid Gas Permeable (RGP) Contact Lenses
- Extended Wear Contact Lenses
- Disposable (Replacement Schedule) Contact Lenses
The type of contact lense that you’ll need depends on the type of condition that you have. Your doctor can recommend the type of lens that will be best suitable for you. The power of your lens is determined after an eye test is conducted.
Some of the advantages of contact lenses that you should be aware of are as follows;
- They offer a wider field view.
- They are better for asymmetrical prescriptions.
- They are cosmetically superior.
- They are more practical for sports.
- They are not affected by weather conditions.
- They have therapeutic and vocational use.
With the development of science and the use of technology, several inventions and upgrades have taken place. The development of contact lenses itself was a major development. Introduction of Acuvue moist lenses is the most recent one. They are made with hydrogel technology.
Hydrogels are gel-like plastics that can hold water to keep your eyes fresh. The oxygen present in them is what keeps the eyes in good health and free of any irritation. They are used in LACREON technology. This technology embeds hydrogels which are a water-containing ingredient in the lens material. We saw what hydrogels and LACREON technology are.
These hydrogel embedded LACREON based lenses are disposable. You can buy a pack of Acuvue moist 90 and use one for each day. It contains 90 lenses and can last for up to 3 months, depending upon your use. If you are using a different type of lens and want to switch to the ones with hydrogels, you should consult your doctor before making the purchase.
For more information on hydrogels and LACREON technology, you can refer to the internet.
