Many people do not feel satisfied with their vision even with prescription glasses. That is because vision is an extremely complex process and there could be other problems affecting it like a higher-order aberration.
HD Eyeglasses Lenses are designed to cater to these patients but like any product, they have their benefits and flaws. Let us look at them in detail.
What are High Definition Lenses?
High Definition Glasses are specially designed glasses that help reduce higher-order aberrations which are beyond the scope of ordinary lenses.
As apparent from the name, they offer HD vision and are especially helpful in reducing nighttime glare making driving easier. They also help with digital eye strain like blue light protective glasses and also provide a much crisper image that would not be possible with ordinary glasses.
The most common type of high definition eyeglass lenses are also called digital lenses since their method of production is fully digital giving a highly detailed cutting process giving you a much more precise product.
Higher-Order Aberrations are visual errors that can not be corrected by normal spherical or cylindrical lenses. These are due to the distortion experienced by the ray of light as it passes through various structures of the eye. So that many problems of these structures can give higher-order aberrations (HOAs).
Things like cataract, corneal damage from surgery or trauma, and dry eye may be possible causes. There is also evidence that HOAs occur after conventional corrective surgery like LASIK.
Benefits of High Definition Lenses:
One of the best things about progressive lenses is that they are made with modern technology that produces lenses that cater better to your specific needs and reduce HOAs, unlike the common prescription lenses.
They are good for people who are using progressive lenses because it is a natural progression for them.
Since they use light better, they can reduce glare and improve nighttime vision helping drivers navigate the traffic more efficiently.
High Definition Eyeglass Lenses Problems:
A major drawback of these lenses is the higher cost. Due to the advanced method used to make them the price naturally goes up in comparison to conventional glasses. The price may be about 25 to 30% higher than ordinary prescription lenses.
Another thing about these lenses is that they are a technology in progress that is yet to undergo a few improvements so that it caters to a greater set of patients. For many centers, this technology may not be available as it is not that well known and widely used.
At this moment in time, this technology is still to evolve further to have a much more profound effect. Presently, not every patient may improve their sight and for the high cost, it may be a risk some people are not willing to take.
What is necessary to know is that they will not solve all your vision problems and certain diseases can just not be treated by glasses alone. It is advised to always check with your ophthalmologist before using these since many people may not need them and still start using them due to the word of mouth.
There is not enough research-backed evidence regarding these glasses so being on the fence for some time about these and only using them when your doctor allows you to maybe a good strategy.
High Definition Lenses are one of the modern advancements in optics. The defining feature they have is the better manufacturing process that caters to the needs of the user and can be a ray of hope for people who do not see improvement with common prescription glasses.
However, it is still a technology in progress and with minimum researches available on their efficacy and inconsistent performance, spending greater than the normal amount for them is something people may be on the fence about.
