Many of us wear glasses for day-to-day vision. Many of us like to be outside when the sun is shining. But many of us don’t want to buy separate sunglasses. So what other options are available to you when you are out in the bright glare of the sun?

Coloured Tints for your Lenses

Essilor Tints

At Lichfield Street Opticians we can offer you coloured tints that can be added to your lenses when you next update your prescription glasses. With a choice of 4 colours – black, brown, grey or grey-green (these are the colours that will not distort your perception of colour in the world around you) – and with a range of tint strengths we can tailor to your needs. They also offer complete UV protection.

Tinted lenses are just right for people with light sensitive eyes especially as they will also help to deal with indoor artificial light. The colours will not alter one’s perception of colours of, for example, road signs, making them especially ideal for drivers – especially when enhanced with lens coating options such as anti-glare. We can offer tints with all of our lenses, including lenses from Essilor and Hoya.

Lens tints are ideal for all walks of life and allow wearers to see colours exactly as they should be seen, in safety.

 

Transitions and Photochromic Lenses

Transitions-Healthy-Sight-In-Every-Light

Transitions and photochromic lenses are clear lenses that will darken on exposure to ultraviolet (UV) radiation – i.e. when one steps outside into the sun with them. Once the UV is removed (for example by walking indoors), they return to their clear state, just like normal lenses. The brighter and hotter the sun, the darker they become – ensuring that you have the best protection from harsh light and glare. They are the perfect solution for those who have increased sensitivity to light but do not want a tint over their glasses at all times.

Sunclips

Sunclips – also known as clip-ons – are another ideal and cost effective way to add the shading effect of sunglasses to your regular spectacles. Put simply, these are UV-filtering tinted covers that can clip onto your existing frame, instantly transforming your day-to-day glasses into sunglasses.

Some of these – flip-up sunclips (see image above) have pegs which grip your frame above the bridge (the segment of frame between the lenses that sits on top of your nose). These are hinged and can be flipped up or down if you need to alternate between tinted or clear vision – ideal for long drives in changing conditions! What’s more, if we do not have the exact size of flip-up sunclip in stock, we can easily trim a larger one down to match your frame exactly.

"Fit-over" Sunclip

You can also get Fit-over sunclips. These are similar to Flip-Up clip-ons but have four small ‘feet’ that grip your frame at the sides of the frame below the arm sides. These offer a more secure fit, at the expense of not being able to flip them up when a tint is not needed.

Both of these types of sunclip are available right now at Lichfield Street Opticians – all with UV400 protection against harmful UVA and UVB rays and with polarised options that offer you extra protection against glare.

For more information, to try sunclips or to view a demonstration of Transitions photochromic lenses in action, please call us on 01902 420348 or pop in to see us!

Ultraviolet light is contained in sunlight and can be harmful to not only our skin but also our eyes. But what is UV and why should we protect ourselves from it’s effects?

UV From The Sun

What Is UV?

Ultraviolet light (UV) is a part of the light spectrum that is shorter than visible light. You cannot see it with your eyes, but it’s there. Although there are many man-made sources of UV, it is produced primarily by the Sun. This sunlight is our main source of vitamin D, which is required to build and maintain strong bones. But most people only need to spend a short amount of time in the sun to make the required amount of vitamin D – far less than the point of developing sunburn.

UV radiation is all around us and can be harmful to our bodies unless we take precautions. For example, as most of us already know, most skin cancers are caused by overexposure to UV from the sun or sunbeds, so when out in the sun we protect ourselves with things like sun creams and parasols. But what most people seldom realise is that our eyes are also highly susceptible to the effects of UV – in particular UVA and UVB rays – that may be factors in many eye conditions such as cataracts. You could also suffer damage to your retinas and cornea in certain environments.

Where am I most at risk of UV damage?

In the UK, UV levels are much lower than in hotter countries closer to the equator, however we are still at risk especially in the summer months. This risk is at its highest at noon in on the hottest days. UV tends to be much higher where there are more reflective surfaces such as sand and water, so protecting your eyes while at the beach, fishing, boating or on holiday is a must. Snow also intensifies the amount of reflected UV light, so good protection is needed in Alpine holiday destinations. It should be noted that there is also higher risk of UV during the winter – especially after snowfall.

So how do we protect our eyes from UV?

We cannot just blank out light from entering our eyes. After all, it’s how we see. But there are ways to filter out harmful UV rays before they enter the eye. Over the next few days we will be showing some of the options that are open to you, to ensure that you are fully prepared for the heated highs of summer!

Summer

Summer is here and with it comes good times – holidays, the beach, tans, ice cream aplenty – all round great fun. But with increased sunlight comes increased risks. We all know that sunlight carries harmful ultraviolet (UV) rays and we all know that UV can be bad news for your skin. So to avoid conditions like sunburn or worse, we spend hundreds of pounds on skin cream products and sun block.

But UV doesn’t affect only your skin – your eyes are also at risk of various conditions that can arise from the damage caused by UV – from corneal flash burns ‘snow blindness’ and is the main cause of cataracts.

Luckily, protecting your eyes and preventing damage caused by the summer months can actually be very simple – by adjusting the simple things in life, such as changing your diet to include more leafy greens, or to look into buying UV-filtered glasses – whether through clear coatings such as Crizal UV, sunglasses, polarised lenses, Transitions or clip-on shades for your existing glasses.

There are also options for your children – who spend more time outdoors and would therefore benefit more from UV protection and sunglasses.

This month, as we spin ever closer to the hottest time of the year, when your eyes are particularly vulnerable, we will look at the options open to you in terms of caring for yours and your family’s eyes during the bright rays of Summer. JH
