The "fused three-prism" for strabismus correction?


I have strabismus with an angle of approximately 20 degrees.
The surgical outcome was not very satisfactory, and I am currently wearing traditional prism glasses.
However, the lenses are thick and heavy.
I found online about a newer type of lens called "fused prism." Is this type of lens widely available now? Is it expensive? I have checked several optical shops, and they all said they do not carry this type of lens.
Thank you.

Understanding Press-on Prism Lenses for Strabismus Correction
Strabismus, commonly known as crossed eyes or squint, is a condition where the eyes do not properly align with each other when looking at an object. This misalignment can lead to various visual problems, including double vision, depth perception issues, and amblyopia (lazy eye). For individuals with strabismus, traditional prism glasses have been a common solution, but they can be bulky and uncomfortable. Recently, press-on prism lenses have emerged as an alternative, offering a potentially more comfortable and aesthetically pleasing option.

Press-on prism lenses are a type of corrective lens that can be applied directly to the surface of existing glasses. They are designed to alter the light entering the eye, helping to align the visual axes of the eyes more effectively. This can be particularly beneficial for individuals with strabismus, as it can help to reduce the symptoms associated with the condition without the need for more invasive treatments.

One of the primary advantages of press-on prism lenses is their versatility. They can be easily added to any pair of glasses, allowing for customization based on the individual's specific needs. This is particularly useful for those who may have difficulty finding traditional prism glasses that fit comfortably or suit their style. Additionally, press-on lenses are generally lighter than traditional prism lenses, which can enhance comfort during extended wear.

In terms of availability, press-on prism lenses are becoming more recognized in the optical community, but they may not be as widely available as traditional options. The technology is still relatively new, and not all optical shops may carry them. If you have visited several optical stores without finding press-on prism lenses, it may be beneficial to consult with a specialized optometrist or ophthalmologist who has experience with strabismus treatment. They may be able to provide recommendations for retailers that offer these lenses or even assist in fitting them.

Regarding the cost, press-on prism lenses can vary in price depending on the specific type and the retailer. Generally, they may be more expensive than traditional prism lenses due to the specialized nature of the product and the technology involved in their creation. However, the investment may be worthwhile for those seeking a more comfortable and effective solution for their strabismus.

It is essential to have a thorough eye examination and consultation with a healthcare professional specializing in strabismus before making any decisions about treatment options. They can provide guidance on whether press-on prism lenses are suitable for your specific condition and help you understand the potential benefits and limitations.

In summary, press-on prism lenses represent a promising advancement in the management of strabismus. While they may not yet be universally available, their potential benefits in comfort and aesthetics make them an appealing option for many individuals. If you are considering this treatment, it is advisable to seek out a specialist who can provide personalized recommendations and support in obtaining these lenses.
