Coronavirus Update


It goes without saying that, irrespective of age, it is extremely important to protect your eyes from the Sun and, more specifically, the hidden dangers of its ultraviolet (UV) rays.

Unbeknownst to many, over-exposure to UV radiation can affect the eyes in a number of ways. It can cause damage to the sensitive skin surrounding the eyes as well as the ocular surface itself. It can also affect the crystalline lens inside the eye, potentially increasing the risk of cataracts developing and/or progressing, and is similarly considered to cause damage to the macula (i.e. the central area of the retina where our best vision is derived from). This in itself can potentially play a part in the development and progression of Age-related Macular Degeneration (AMD).

Obviously the best way to protect your eyes from UV radiation is to wear sunglasses (of some form) and here at John Weygang Optometrists LLP we recommend ones that are guaranteed to provide 100% UV protection (especially with respect to harmful UVA and UVB radiation).

Thankfully we are able to provide such sunglasses for you as we offer a wide range in many different shapes, styles, tints and lens options. Many of these can be made to your individual spectacle prescription if needed and they are always produced to the same high standard as our clear spectacles. They can be single vision, bifocal or varifocal lenses and can also be made thinner for those high spectacle prescriptions.

We are aware that different lifestyles and conditions often call for different types of sunglasses. This is why we are always happy to advise accordingly and recommend the best shape, style, tint and lens option to meet your needs whilst ultimately ensuring that your eyes receive the best UV protection possible.

On that note, sunglasses are available in many forms and some examples of those that we can provide include:

  • Photochromic

Also known as ‘Reactolites’ or ‘Transitions’, these are clear lenses that darken to become tinted lenses (i.e. sunglasses) on direct exposure to UV radiation. They can help your eyes adapt to changing light levels whilst eliminating the inconvenience of having to constantly put on/remove a pair of sunglasses. Although they do provide 100% UV protection when darkened, it is important to note that they do not work in the car as the UV blocking filter in the windscreen will prevent them from darkening.

  • Polarised

These are sunglasses that are highly effective in terms of combating the effect of horizontal glare (e.g. like that experienced when driving on a wet road with the Sun low in the sky or when participating in water-based activities). They also provide 100% UV protection.

  • Wraparound

These are close-fitting sunglasses that provide 100% UV protection all the way around. They also serve the purpose of reducing the effect of wind and light at the sides, making them ideal for sports.

  • Clip-on

These are essentially tinted lenses (i.e. sunglasses) that can be clipped on over the top of your clear spectacles when needed and so saves you having to carry a separate pair of sunglasses around with you. To make this even easier for you, we supply ones that are magnetised. This ensures that they stay where they are supposed to when they are needed and conversely that they are easy to remove when they are not.


We are proud to be a supplier of Chemistrie, a patented magnetic lens layering system that allows a wearer of prescription eyewear to attach a variety of lenses to their frame by means of magnets embedded near the edges of the lenses. The clip-on lenses available include the Chemistrie Sunlens, offering 100% UV protection via a choice of 24 polarised lens colours, as well as the Chemistrie 3D and the Chemistrie+ Reader lenses.
