Incredible prescription contact lenses exist. But how can something so insignificant alter your view so significantly? By distorting light, prescription contact lenses focus light on the retina, where vision receptors receive data and convey it to the brain.
Refraction is the term for this type of light manipulation, and eyeglasses work on the same principles. Prescription contact lenses adhere to the tear film that covers the eye and are undetectable to others. Because of this, some people choose contacts over glasses to wear.
Lenses: How Does It Work?
Both contact prescription glasses and lens function to correct your vision by reorienting light rays to hit your retina in the right place and give you clear vision. Depending on whether you are nearsighted or farsighted, they change the path of light differently.
The eyes are less focused on it due to prescription lenses diverting the light beams so that the retina, where it belongs, gets them. Prescription lenses aid in sharpening the eyes’ ability to focus so that the retina can accurately see pictures since the light has already reached a certain point by the time it reaches it.
An Overview Of Prescription Contact Lens History
The first modern prescription contact lenses arrived in the 1970s, although scientists were aware of their potential as early as the 16th century, thanks to developing theories of optics. Unfortunately for these innovators, mass production of contacts began much later, thanks to the developing of new materials and techniques.
Prescription contact lenses For Daily Disposable Versus Extended Wear
To provide lenses that are more pleasant and long-lasting for consumers, contact lens makers keep innovating. As a result, customers have two options for how long they may wear contacts: daily disposable or extended-wear (EW) lenses.
Said, daily disposable contacts are one-and-done lenses that are thrown away at the end of the day. However, wearing daily contacts has several benefits, such as:
- Convenience: Since daily prescription contact lenses are only worn once, there is no need to clean and disinfect
- Reduced risk of infection: The lenses are sterile when delivered and only worn once. This reduces the possibility of germs growing on the contacts.
What Are The Advantages Of Wearing Prescription Contacts?
- They are worn directly on the eye and offer less-distorted, more “natural” vision.
- Your nose, ears, and any other bothersome weight are all gone.
- They eliminate the use of frames, bringing the full field of view into sharp focus (which is why many athletes wear them)
- There is no requirement for prescription sunglasses, so you may wear whatever stylish pair of sunglasses you choose. Prescription contact lenses do not fog up with temperature changes or gather moisture in rain and snow.
- In contrast to how it is with glasses, there are no lens reflections.
Conclusion
If you’re looking for prescription contact lenses, do your homework first. Figure out what type of contacts you want, the size of your pupil, the fit, and how much you’re willing to spend. Remember the importance of comfort, and ensure you only get your prescription from a qualified eye doctor if you wear some prescription contacts.
