# **Best Contact lenses that can correct color blindness**


Think about the world being seen in subdued tones, such as the grey sky and grey grass. While most persons with **color blindness** are unable to perceive certain hues, some may see everything in this fashion. You can test yourself for **[color blindness](https://colorblindtest.us)** here.

Additionally, the colored contact lenses being developed for the disorder now have a risk of instability and damage. To establish a safer way to perceive colors, researchers have now reported injecting contact lenses with gold nanoparticles.

For those who are **Colorblind**, several daily tasks, such as deciding if a banana is ripe, choosing coordinated clothing, or stopping at a red light, might be challenging.

Red-tinted spectacles can make red and green tints more noticeable and easier to see for persons with this genetic disease, who typically have problems distinguishing between red and green hues. The thick nature of these lenses prevents them from being used to correct vision issues.

As a result, scientists are now working on creating unique Colored contact lenses. Despite improving red-green Color perception in clinical trials, the prototype hot-pink Colored lenses leached dye, raising questions regarding their safety. Due to the way they scatter light, non-toxic gold nanocomposites have been used for millennia to create "cranberry glass."

Therefore, Ahmed Salih, Haider Butt, and colleagues investigated if adding gold nanoparticles to contact lens material rather than dye may safely and efficiently enhance red-green contrast.

The gels were produced by equally blending rose-colored gold nanoparticles into a hydrogel polymer, which filtered light between the wavelengths of 520 and 580 nm, where red and green overlap.

The best contact lenses were those with gold nanoparticles that were 40 nm broad, as these particles did not clump or filter more Color than was necessary during tests.

These lenses did not harm lab-grown cells in Petri dishes and exhibited water-retention qualities comparable to those of commercial lenses.

Finally, the researchers made direct comparisons between their novel material and two pairs of Colored spectacles that are currently on the market as well as their previously created hot-pink dyed contact lens. Compared to the glasses, the gold nanocomposite lenses were more discriminating in the wavelengths they blocked.

The new lenses matched the dyed contact lenses' wavelength range, indicating that patients with red-green Color difficulties may use the gold nanocomposite lenses without having to worry about potential safety issues. The next step, according to the experts, is to carry out clinical studies on real people to gauge comfort.

## **The Three Main Type Contact Lenses**


The figures show that contact lenses are a terrific alternative for vision correction for people of all ages. The American Optometric Association reports that more than 30 million Americans wear contact lenses, with more than two-thirds of them being women.

The use of contact lenses is also on the rise as a result of recent developments in lens technology that have made them more pleasant than before. Today, even those who previously had trouble wearing contacts are frequently acceptable candidates for contact lenses.

This post is for you if you are thinking about buying or want contact lenses. We provide you with some fundamental details about the three main types of contact lenses so that you can make an informed decision when you see your eye doctor. Visit an Eye Associates location for a thorough contact lens assessment to determine which lenses could be ideal for you to receive the most up-to-date, accurate information.

### **Contact Lenses Categories:**

You should be aware of the following three primary types of contact lenses:

**Hybrid Lenses:-**

The two types of contact lenses mentioned above are combined in hybrid lenses. A soft lens material surrounds a stiff gas-permeable plastic core used in hybrid contacts. With this hybrid design, you get the relaxation of soft lenses with the clarity of GP contact lenses.

Hybrid contact lenses can be more difficult and time-consuming to install, and they are more expensive than soft or GP lenses. Due to these factors, fewer than 5% of Americans who wear contact lenses choose to use hybrid lenses.

**Soft Lenses:-**

Soft contact lenses, also known as hydrogel or silicone hydrogel lenses, are extremely thin, moist, and constructed of polymers that absorb water, giving them a gel-like sensation. The water in soft lenses makes up around 50% of their weight, making them incredibly lightweight and comfortable to wear.

The most common kind of contact lens is without a doubt one with soft lenses. In the United States, soft lenses are worn by almost 90% of people. Since silicone hydrogel lenses transport more oxygen to the surface of the eye than traditional hydrogel lenses, they make up the majority of these lenses.

**Rigid Gas Permeable Lenses:**

These rigid plastic contacts, also known as GP contacts, frequently offer clearer, more stable vision than soft lenses because of their stiff construction. The likelihood of some contact lens-related eye issues is reduced by the fact that GP contact lenses deliver more oxygen to the eye's surface than many soft lenses. GP lenses often fit closer to your eye than soft lenses because of their smaller diameter.

However, some people find it difficult to wear the lenses comfortably due to their rigidity and bigger profile, which might take some getting used to. Due to these factors, rigid gas-permeable lenses account for fewer than 10% of contact lenses worn in the United States.

## **How To Choose the Right Lenses:**

The shape of your lens will depend on the nature of your eyesight issue. If you are nearsighted, you will require a concave lens (curves inward). If you are farsighted, a convex lens (which curves outward) will help. Your cornea is structured incorrectly if you have astigmatism, thus your lenses may be more cylindrical.

### **Tips to Help You Pick the Right Lenses**

**Multifocal Eyeglass Lenses**


You most likely use glasses with multifocal lenses, such as bifocals or trifocals, if you are in your mid-40s or older. These can correct your vision with two or more prescriptions. This kind of lens used to be easy to identify thanks to the line between the two pieces. But many of today's items appear seamless.

* **Bifocals.** a multifocal that is most typical. There are two components to the lens. Vision at a distance is aided by the upper portion. Near eyesight is provided by the bottom half. They are typically administered to adults over 40 who are having trouble focusing. **[Presbyopia](https://www.nei.nih.gov/learn-about-eye-health/eye-conditions-and-diseases/presbyopia)**, an age-related alteration that damages the lens of your eye, is to blame for that.

* **Trifocals.** These have the third part and are bifocals. It is located above the lens's bifocal area. You can view things within range, like a computer screen, by looking through it.

* **Progressives.** lenses are another option. They don't have a line and start with your range prescription at the top before gradually advancing to your full reading medication at the bottom.

Consult your **eye doctor** if you have any queries regarding which type is best for you. They can assist you in determining which one best suits your needs in terms of lifestyle and eyesight.

**Eyeglasses for Children**

When it comes to improving your child's vision, a positive experience at the eye doctor is only half the battle. The challenging aspect is getting them to put on their new spectacles every day. Find the appropriate eyewear using these strategies to make them desire to wear them.

* **The frames are in place.** They shouldn't press against their nose or ears or let their face droop. Now and again, check the areas of their face where they interact to make sure the skin isn't disturbed.

* **Get the appropriate medication.** Your child's prescription can be off if they claim that they can't have seen with their glasses or peer over the top of them. Return to your eye doctor or optician and get it examined.

* **Begin gradually.** At first, have them sit down and wear the glasses for brief periods. Starting first thing in the morning is also the finest option. then gradually lengthen the time they keep them on.

* **Make a timetable.** Make wearing their glasses a daily habit. Encourage them to put them on when they get dressed in the morning and take them off when they go to bed at night.

* **Don't stop praising.** Every time they put on their glasses, tell them how well they're doing.
