Blokz Basic Vs High Index Buying Guide
Clarity and Visual Acuity
When comparing Blokz Basic and High Index lenses, clarity is a primary consideration. Blokz Basic lenses offer excellent clarity for everyday use, providing sharp vision across a wide range of prescriptions. High Index lenses, however, can provide even better clarity, especially for individuals with strong prescriptions. This is due to their thinner profile, which minimizes distortions at the edges of the lens. This translates to a clearer and more visually accurate experience, particularly when looking through the periphery of the lens. The difference is noticeable in tasks requiring fine visual detail.
Thickness and Weight
One of the most significant advantages of High Index lenses is their reduced thickness and weight compared to Blokz Basic. High Index materials are denser, allowing for the same refractive power in a thinner lens. This is particularly beneficial for those with high prescriptions, as it reduces the “coke bottle” effect and overall weight of the glasses. Blokz Basic lenses are thicker, especially for stronger prescriptions, which can lead to discomfort and a less aesthetically pleasing appearance. The lighter weight of High Index lenses also contributes to greater comfort during extended wear.
Cost and Affordability
The cost difference between Blokz Basic and High Index lenses is a crucial factor for many buyers. Blokz Basic lenses are generally more affordable, making them a budget-friendly option for those with mild prescriptions or who prioritize cost savings. High Index lenses, on the other hand, typically come with a higher price tag due to the more advanced materials and manufacturing processes involved. The added expense of High Index lenses can be justified by the improved visual clarity, thinner profile, and enhanced comfort, especially for those with stronger prescriptions who can benefit the most from these features.
Impact Resistance and Durability
The durability of eyeglass lenses is important for their longevity. Blokz Basic lenses are generally made from more impact-resistant materials, making them a robust choice for active lifestyles or environments where glasses are at risk of impact. High Index lenses, while offering excellent optical properties, are often slightly less impact-resistant than Blokz Basic. However, advancements in lens coatings can significantly improve the scratch resistance and overall durability of High Index lenses. Consider your lifestyle and potential risks when choosing between the two options.
Cosmetic Appearance and Aesthetics
The cosmetic appearance of your eyeglasses is also an important consideration. The thinner profile of High Index lenses offers a more aesthetically pleasing look, particularly for those with strong prescriptions. This is because they reduce the thickness and bulkiness of the lenses, minimizing the “coke bottle” effect. Blokz Basic lenses, being thicker, can make the eyes appear smaller and the frame look less stylish, especially with high prescriptions. This difference in appearance can significantly impact the wearer’s confidence and overall satisfaction with their glasses.
Prescription Strength and Suitability
The suitability of Blokz Basic and High Index lenses largely depends on your prescription strength. For mild prescriptions, Blokz Basic lenses often provide adequate vision correction and are a cost-effective choice. However, for those with moderate to high prescriptions, High Index lenses become increasingly advantageous. The thinner, lighter design of High Index lenses offers superior visual clarity, improved comfort, and a more attractive appearance, making them the preferred option. Consult with your optometrist to determine the most appropriate lens type for your specific needs.

Frequently Asked Questions
What are Blokz Basic lenses?
Blokz Basic lenses are standard prescription lenses made from a common plastic material. They offer good vision correction and are a cost-effective option for many. They are suitable for most prescriptions, though they are thicker and heavier than high-index lenses, especially for stronger prescriptions. They provide good clarity and are a solid choice for everyday wear.
What are High Index lenses?
High Index lenses are made from a denser plastic material than Blokz Basic lenses. This allows them to bend light more efficiently, enabling thinner and lighter lenses. They are ideal for individuals with strong prescriptions, providing better clarity and a more aesthetically pleasing appearance by reducing the thickness and weight of the glasses. They also offer improved visual acuity.
Which lenses are better for strong prescriptions?
High Index lenses are generally better for strong prescriptions. Their thinner profile and lighter weight provide significant advantages, including improved comfort, reduced distortions, and a more attractive appearance. While Blokz Basic lenses can correct strong prescriptions, they become thick and heavy, which can be uncomfortable and cosmetically less appealing. High Index offers superior optical performance in this scenario.
Are High Index lenses more expensive?
Yes, High Index lenses are typically more expensive than Blokz Basic lenses. The increased cost reflects the use of specialized materials and advanced manufacturing processes. However, the benefits of improved clarity, thinner profile, and lighter weight often justify the higher price, especially for those with higher prescriptions. The investment provides better overall vision and comfort.
Do High Index lenses offer better clarity?
Yes, High Index lenses often provide better clarity, particularly for those with strong prescriptions. This is due to their ability to minimize distortions at the edges of the lens, resulting in sharper and more accurate vision. The thinner design also reduces the “coke bottle” effect, further enhancing the clarity and visual experience. This allows for a more natural viewing experience.
Are High Index lenses more durable?
High Index lenses are generally durable, but they may be slightly less impact-resistant than Blokz Basic lenses. However, advancements in lens coatings can significantly improve the scratch resistance and overall durability of High Index lenses. Consider your lifestyle and potential risks when choosing, and discuss coating options with your eye care professional to enhance durability.
Which lens should I choose for my child?
For children, the best choice depends on their prescription and activity level. If the child has a strong prescription, High Index lenses may provide better comfort and appearance. However, Blokz Basic lenses are often more impact-resistant. Discuss your child’s needs and lifestyle with your eye doctor to determine the most suitable option, considering safety and visual clarity.
Final Verdict
Choosing between Blokz Basic and High Index lenses requires considering factors like prescription strength, budget, and desired aesthetics. While Blokz Basic offers a cost-effective solution, High Index lenses excel in visual clarity, reduced thickness, and enhanced comfort, particularly for those with higher prescriptions. High Index lenses provide a superior overall experience.
