The importance of UV protection: how to safeguard your vision this summer

Summer is finally upon us and we can all bask in the glorious sunshine (and then run for cover when the rain arrives). We all think we know the dangers of the sun’s rays: slapping on sun lotion is almost second-nature – but few of us realise the damage sun light could be doing to our eyes.

The sun is both vast and vastly far away: in fact, it takes nearly eight and a half minutes for the sun’s rays to reach earth. Despite our distance from the sun, its light is still powerful, delivering light that is visible and invisible, harmless and harmful.

Be my sunshine

Alongside visible light and invisible infrared rays, the sun blasts us with three varieties of ultraviolet light: UVA, UVB and UVC. UVC is mostly absorbed by the earth’s atmosphere before it reaches us, but we need to take steps to protect both our skin and eyes from UVA and UVB rays.

UVB is important for vitamin D formation (and gives us a nice tan), so a little is ok. But too much causes sunburn. UVA is also harmful if our eyes or skin are exposed for too long.

The best way to protect your eyes

Sunglasses are much more than just a fashion accessory. Whether non-prescription or prescription they’re vital for protecting your eyes from UVA and UVB, helping to slow or even prevent the development of eye conditions like cataracts and macular degeneration.

Our quick tips for beating UV rays:

  • Your eyes are 10x more sensitive to UV than your skin, so wear sunglasses as often as you can when outside.
  • Choose sunglasses rated to block at least 95% of UVA light.
  • Don’t think it’s safe on overcast days: 90% of UV rays penetrate cloud.
  • Kids should wear sunglasses. In fact, 80% of the total amount of UV light that enters the eye over a lifetime will do so before the age of 18.
  • …but make sure your children’s sunglasses are properly UV rated. Many toy sunglasses don’t offer proper protection.

Migraine glasses: can tinted lenses help with headaches?
If you experience migraines or frequent headaches, you may have noticed that light can make symptoms feel worse. Bright environments, glare or certain patterns can trigger discomfort and make it harder to focus. Many people searching for migraine glasses in the UK are looking for ways to reduce these visual triggers. While glasses cannot treat migraines themselves, certain lenses, including carefully selected tinted lenses, can help improve visual comfort and reduce the impact of light. If you are exploring your options, it can also help to understand how tinted lenses for everyday comfort and clarity and everyday use.   Why light can trigger migraines and headaches For many people, migraines are closely linked to how the brain processes light. Bright or flickering light, glare from screens, or high-contrast environments can place extra strain on the visual system. This can lead to: Increased light sensitivity (photophobia) Eye strain and visual discomfort Difficulty focusing Headaches triggered or worsened by bright environments Some people may also experience visual stress, where patterns or contrast make text or surroundings feel uncomfortable or unstable.   What are migraine glasses? The term migraine glasses is often used to describe glasses designed to reduce light sensitivity and visual discomfort. In many cases, these involve tinted lenses that help soften brightness and reduce the intensity of certain light wavelengths. One commonly referenced option is FL-41 tinted lenses, which use a rose-based tint designed to filter specific parts of the light spectrum. Some people find this type of tint more comfortable, particularly in environments with artificial lighting or screen use. However, there is no single tint that works for everyone, and results can vary.   Do FL-41 lenses work for migraines? FL-41 lenses are often discussed in relation to migraines, and some people report improved comfort when using them. They are designed to reduce certain wavelengths of light that may be linked to visual discomfort. However, it is important to understand that: They do not prevent or treat migraines Their effectiveness varies between individuals They are one of several tinted options, not the only solution For many people, a personalised approach to tinted lenses can be more effective than choosing a single standard tint.   How tinted lenses can help Tinted lenses work by reducing overall brightness and improving how your eyes respond to light and contrast. For some people, this can help: Reduce visual discomfort in bright environments Soften glare from screens and artificial lighting Make reading or focusing feel easier Create a more relaxed visual experience If your symptoms are linked to light sensitivity or visual stress, you may also benefit from understanding the different types of tinted lenses and colours available, as some tones feel more comfortable than others.   Tinted lenses vs blue light glasses You may also come across blue light glasses when searching for migraine solutions. Blue light lenses are designed to filter a portion of light from digital screens and may help reduce glare for some people. However, there is currently limited evidence to show that they reduce migraines or prevent headaches. These lenses can enhance warmer tones, meaning a white background may appear slightly softer or more sepia in tone, similar to the setting often used on e-readers. Tinted lenses tend to offer a broader approach by reducing overall brightness and improving contrast, which may feel more beneficial if your symptoms are linked to light sensitivity rather than screen use alone. Compare blue light lenses vs tinted lenses to understand which is right for your needs.   Finding the right tint for you There is no one-size-fits-all solution when it comes to migraine glasses. The way your eyes respond to light is highly individual. Some people find relief with softer tones such as rose or grey, while others benefit from more specific colours tailored to their visual response. If visual stress is a contributing factor, a personalised assessment such as a colourimetry visual stress test can help identify which tint feels most comfortable for you.   Start with a full eye examination Before choosing tinted lenses or migraine glasses, it is important to understand what is causing your symptoms. A comprehensive eye examination allows us to assess your vision, check for underlying eye conditions, and understand how your eyes respond to light. From there, our qualified dispensing opticians can guide you towards the most appropriate options for your needs.   Takeaway Migraines and headaches can affect everyone differently, and the way your eyes respond to light is highly individual. While glasses cannot treat migraines, the right lenses can help reduce visual triggers such as brightness and glare, making everyday environments feel more comfortable. Tinted lenses, including options similar to FL-41, may help some people by softening light and improving visual comfort, particularly where light sensitivity or visual stress is a factor. However, there is no single solution that works for everyone, which is why a personalised approach is so important. At Leightons, we take the time to understand your symptoms, your lifestyle and how your eyes respond to light. Starting with a comprehensive eye examination by one of our optometrists, our qualified dispensing opticians can advise on the correct lens solution or you, whether that involves tailored tinted lenses or further assessment such as colourimetry.
