Glasses or Contact Lenses

Contact lenses for colorblind people and colorblind glasses are both used to assist people with color blindness, helping them to see and distinguish colors like normal people.

Contact lenses for colorblind people

Colorblind contact lenses are a type of glasses used to assist people with color blindness, helping them to see colors like normal people. They work by using filters specifically designed for each type of color blindness, varying the wavelengths of each color that enters your eye. 

Advantages:

• Colorblind contact lenses cause less interference and distortion of vision.
• Color-corrected Aspheric lenses help to reduce chromatic and spherical aberrations, which makes them great for many applications where image quality and accurate results are important.
• Contact lenses also have the effect of increasing aesthetics, creating a sense of comfort and confidence in communication for users;
Convenience: Compact, lightweight, easy-to-use contact lenses, without frames, are suitable for people who play sports or do jobs that require intense activities.
• Wider field of vision: Unlike classic framed glasses that are limited by the frame, contact lenses can move according to eye movements, making it easier for the wearer to see their surroundings.
• Eye protection: Most contact lenses today have a layer of UV protection, helping to protect the eyes.

Defect:

• Improper use can cause scratches, infections, or ulcers of the cornea. In addition, when wearing contact lenses, many people also have an epithelial disease caused by glasses that damage the outermost layer of cells on the cornea.
• Daily glass cleaning should be done regularly because the lens is in direct contact with the epithelium on the cornea. When learning about the pros and cons of contact lenses, busy people will find it relatively inconvenient.
• Eyes are easily irritated when wearing glasses for an extended period of time because the cornea must constantly rub directly against the glasses. As a result, many people experience dry or inflamed corneas.
• For those who have never used glasses before, they will find them relatively difficult to wear.

Color-blind glasses:

Colorblind glasses are used with optical filters, which are specifically capable of removing certain wavelengths of light, allowing for a more accurate light ratio setting before reaching the eye. As a result, people with color blindness syndrome can distinguish colors much more clearly.

Advantages:

• Helps people with color blindness easily distinguish colors.
• Color-blind glasses limit direct contact with the eyes. Reduces the chance of developing an infection. Suitable for adults and children.
affordable, economical, and easy to use.
• Color-blind eyeglasses can help protect your eyes from dust, wind, and other harsh environmental elements.
• If your eyes are sensitive or dry, then colorblind glasses are a good option; they are less aggravating than contact lenses.

Defect:

• Because you wear glasses near your eyes, your field of vision narrows. People who are wearing it for the first time may struggle to see their peripheral vision.
• Choosing the wrong frame will affect the aesthetics.
• Glasses can make your eyes look bigger or smaller, making you look unnatural.
• When participating in combat sports, glasses cannot be worn.
• When riding in the rain, fog will affect visibility.

Above are the advantages and disadvantages of using glasses or lenses. So think and make sure your criteria like comfort, lifestyle, convenience, aesthetics, and budget—are met before making a decision.
