Colored contact lenses are used for more than what typically comes to mind— fashion eye color enhancement and movie aesthetics. They can also be used therapeutically or prosthetically to alter different vision disfigurements. In this article, we will throw light on the various vision impairments and ways colored contact lenses can help people with vision disfigurements to select and manage proper contact lenses for various clinical uses.
Corneal opacity occurs when the cornea becomes scarred. This stops light from passing through the cornea to the retina, resulting in a white or cloudy appearance. Patients with corneal opacification can benefit from prosthetic contact lenses. The size and location of the corneal scar and the color of the iris will dictate the type of lens needed. For patients who can still see, we recommend you choose a clear pupil. Consider a SiHy (silicone hydrogel) lens material if the cornea is jeopardized.
When working with iris abnormality like heterochromia, where a person’s irises are different colors, choose tinted or opaque contact lenses. They can cosmetically alter the differing iris colors of two eyes to make them look similar. Enhancing tints blend with the underlying iris for a more natural look. Many actors with heterochromia use these contacts when required for the character they are playing.

For albino patients whose lack of pigmentation induces extreme photosensitivity, darker-colored contact lenses can act as filters. Compared to sunglasses, contact lenses provide complete coverage, limit glare, and reduce surface reflection. However, sunglasses and hats should still be worn as a precautionary measure.
Bothnia dystrophy is an autosomal recessive disease of the retina, characterized by an early onset of night blindness followed by macular degeneration and eventual loss of vision later in life. Uniform, dark brown contact lenses can be used on patients with Bothnia dystrophy. These lenses maximize visual capacity by decreasing glare and extreme light sensitivity to improve orientation and fluidity. The darkness of the tint is flexible depending on the light intensity of different seasons.

Cone dystrophy is a generic term for rare eye disorders that affect the cone cells of the retina. Cone cells allow a person to see color and fine detail, and they work best in bright light. The cone dystrophies can cause a variety of indications such as decreased visual clarity when looking straight ahead, a reduced ability to see colors, and an increased sensitivity to light.
Tinted contact lenses decrease photosensitivity, enlarge the peripheral visual field and enhance the clarity of long-wavelength stimuli in bright light. Red-brown tints may be more fitting for patients with residual cone function, and magenta may be helpful in cases of blue cone monochromatism.
Transparent-Tinted Contact Lenses
Transparent-tinted contact lenses are fit to reconstruct a patient’s perception, especially in the case of sportspeople and people with color blindness. For example, yellow tints can enhance the incoming image of a baseball. They can reduce stray light affecting the cornea, iris, lens, and retina, efficiently restricting visual glare. The transparent tint overlays the natural iris, causing it to change color and allow a more natural look.
Be Aware Of Complications
Colored contact lenses are underused but adaptable options for a population of patients who stand to benefit from them. Therapeutic colored contact lenses can help those who have a working vision to see the world more comfortably. For those who require extra support, prosthetic colored contact lenses can enhance their physical appearance. Colored lenses help improve the quality of many lives.
But with positives come negatives too. The risk of infection is invariably higher for those who wear contact lenses. Though a prosthetic lens may be cosmetically appealing, a disposable, computer-generated, printed SiHy contact lens may be healthier.
Follow a good lens care routine for safe contact lens wear.
- Always wash, rinse, and dry your hands before touching your contact lenses.
- Clean contact lens cases after each use using fresh, sterile contact lens solution.
- Change the contact lens solution in the lens case after every use.
- Do not use the contact lens more than the prescribed time.
If you notice any issue with your contact lenses such as eye-stinging, burning, itching, eye pain, or discomfort, take your lenses out and consult your eye doctor immediately.
