Dear Hyde Eyecare Patients,
In these uncertain times, we wanted to reach out to you personally about what we are doing here at Hyde Eyecare to support you and our employees. As the situation around novel coronavirus (COVID-19) continues to evolve, we are doing everything we can to ensure your Health is our top priority as it has always been, the safety and security of our patients and employees remains our highest priority. We take great pride in maintaining the highest standards of cleanliness and hygiene. In response to the coronavirus, we have taken additional measures developed in consultation with global and local public health authorities (including the WHO and CDC) to make our cleaning and hygiene protocols even more rigorous:
• Our team members are receiving ongoing briefings and enhanced operating protocols.
• We have increased the frequency of cleaning & sterilizing our public areas (including exam rooms, optical gallery, lobbies, elevators, private offices, door handles, bathrooms, etc.) and have continued to use hospital-grade disinfectant.
• We have increased the deployment of antibacterial hand sanitizers and wipes. We remain committed to offering you the best eye care possible. We will be flexible if your appointment needs to be rescheduled and will always be here if an eye emergency arises.
At Hyde Eyecare, we believe it is in challenging times like these that the power of good “sight” is needed most of all. We remain committed to serving you and our community for many years to come.

Glass lenses. When Dr Hyde began practice 40 years ago, all eyeglass lenses were made of glass. Glass was heavy and could break or chip easily and caused many eye injuries potentially causing serious harm to the eye or even loss of an eye. Glass lenses are very expensive. For these reasons, glass lenses are no longer used for eyeglasses except on a special circumstance.
Because of its light weight (about half the weight of glass), low cost and excellent optical qualities, plastic remains a popular material for eyeglass lenses even today.
Polycarbonate is lighter and significantly more impact-resistant than plastic, making it a preferred material for children's eyewear, safety glasses and sports eyewear.
A newer lightweight eyeglass lens material with similar impact-resistant properties as polycarbonate is called.
These lenses are thinner and lighter than plastic lenses because they have a higher refractive index. The higher the ‘refractive index” faster the light travels and the thinner the eyeglass lens is. There 7 different categories of refractive index.
The Aberration (Abe) number is a measure of aberration in the eyeglass lens. This quality number tells how the lens disperses different wavelengths of light as light passes through it. Lens materials with a low Abbe value have high light dispersion, which can cause noticeable distortion and chromatic aberration — an optical error visible as colored halos around objects, especially lights. It makes night vision terrible to drive. On cheaper lenses aberration is easily noticeable when looking through the periphery of eyeglass lenses.
The size and shape of your eyeglass frames will affect the thickness of your lenses, especially if you have a strong prescription. Choosing a smaller, well-centered frame can significantly reduce the thickness and weight of your lenses, regardless of the lens material you choose.
Generally, the thinnest lenses for your prescription will be aspheric lenses made of a high-index material, worn in a small frame.
For the most comfortable, durable and best-looking glasses, the following lens treatments are essential.
Cumulative exposure to the sun's harmful ultraviolet (UV) radiation over a person's lifetime has been associated with age-related eye problems including cataracts and macular degeneration.
For this reason, You should protect your eyes from the sun's harmful ultraviolet (UV) radiation beginning in early childhood.
The fact that all eyeglass lens will scratch is obvious. All plastic and high-index plastic lenses require anti-scratch coating for adequate lens durability. This doesn’t mean “Scratch Proof” but Scratch resistant.” Today's modern anti-scratch coatings make your eyeglass lenses very durable and scratch-resistant. But if you're hard on your glasses or you're buying eyeglasses for your kids, ask about lenses that include a warranty against scratches for a specific period of time.
An anti- Glare or anti-reflective coating makes all eyeglass lenses better. Anti-Glare eliminate reflections in lenses that reduce contrast and clarity, especially at night. They also make your lenses nearly invisible, so you can make better eye contact and you and others aren't distracted by reflections in your lenses. Anti-Glare lenses are also much less likely to have glare spots in photographs.
This lens option enables eyeglass lenses to darken automatically in response to the sun's UV and then quickly return to clear when indoors. If you are not buying a pair of prescription eyeglasses, this is a must with all the scientific data we now have on how harmful UV is to the eye.
