Dry eye

  • What is dry eye? Open

    Your eyes are naturally lubricated by a layer of tears. Tears have a watery part and an oily part. Dry eye syndrome, or dry eye disease, occurs if the eyes don’t make enough tears, or the tears evaporate too quickly. Your eyes may become irritated, worsening as the day goes on. Dry eye can also be known as keratoconjunctivitis sicca.

  • What causes dry eye? Open

    There are a range of factors that cause dry eye. Increased use of computer screens can slow your blink rate which reduced the spread of tears across your eyes. Contact lenses can play a factor in dry eye. Dry eye tends to increase with age, and with the menopause in women. Some medications such as betablockers, the pill and antihistamines can worsen dry eye too.  If you think you may have dry eye book as assessment with your optician. Some opticians specialise in treating dry eye.

    If your eyes both become irritated as the day goes on, and this happens every day, you may have dry eyes. You may feel that your eyes are simply irritated or that they burn. Some people find their eyes are gritty on waking. Surprisingly, people with dry eye may find their eyes water as the eye tries to relieve irritation by increasing the production of tears. Your vision may be normal, or it may become blurry as the day goes on but clear on blinking. If you think you may have dry eye book as assessment with your optician.

  • What causes dry eye? Open

    Tear production is something that generally happens without any effort or thought – so it can be a shock when it goes wrong. There are a number of factors that can cause problems. Your eyes may not produce enough tears, or the oily layer that stops the tears evaporating may be of poor quality. Dry eye symptoms can be worsened by dry, sunny and windy climates, contact lenses, eye conditions such as blepharitis, some medications including anti-depressants and diuretics, and hormonal changes such as the menopause, pregnancy, or going onto the contraceptive pill. Tear quality and quantity tends to decrease with age too. Air conditioning and computer use can exacerbate dry eye. People who have had certain types of laser eye surgery may find they have dry eye syndrome after surgery: this usually clears up within a few months but for some people the problem persists. If you think you may have dry eye book as assessment with your optician. Some opticians specialise in treating dry eye.

Discuss this with your contact lens optician or optometrist and they can advise on the best lens to try. You may also want to alter your pattern of lens wear or solution: again, seek professional advice before making any changes like this. Your optician can also suggest suitable eye drops that will work with your contact lenses. Seek advice before purchasing eyedrops as some are unsuitable for contact lens wearers.

  • How do you treat dry eye? Open

    There are a number of ways to treat dry eye. It is important to find out the cause before starting treatment. If your Meibomian glands are not producing enough oil, hot compresses or massage with a special machine can help improve this. Omega oil supplements can also improve the quality of the oily secretions that are needed to help your tears. Some people have a tiny mite which irritates the eyelashes: this can also worsen dry eye. If you have this mite, your optician can use a special procedure to remove the mites which cuts irritation.

  • Should I use eyedrops with or without preservatives to treat my dry eyes? Open

    Many eye drops contain preservatives to stop bacteria growing inside the bottle. These preservatives aren’t good for everyone. Contact lens wearers should avoid drops with preservatives which can build up inside the lenses. People who use eyedrops more than six times daily and those with severe dry eye who are using treatment over a long period day are better with preservative-free eye drops. Talk to your optician about whether the best eyedrops for you.

Talk to your doctor or pharmacist about this as there are devices which make it easier to squeeze a bottle and ensure the drops reach your eyes.

  • What are the options for surgery for dry eye? Open

    If you have severe symptoms from dry eye that do not respond to other treatments you may find surgery is your best option. One procedure, called punctal occlusion, involves inserting a small plug in the ‘puncta’, a tiny hole in the inner corner of your eyelids. This reduces the drainage of tears from your eye. Temporary silicone plugs are used at first to see if this helps. If it does, then more permanent plugs are used, or heat can be used to seal the punctal drains. Talk to your optician about whether this treatment might help you.

  • What can I do at home or work to help my dry eyes? Open

    Talk to your optician about how to improve your dry eye. There are plenty of actions you can take to help your symptoms. Protect your eyes from wind and hot dry air, smoke and dust. Wrap around glasses can help with this. Specialised glasses called ‘moisture chamber’ spectacles help your eyes retain moisture. Try to avoid eye makeup and see if that improves your symptoms. When reading, writing or using a computer ensure that you blink more often, and every 20 minutes take a break. An air humidifier moistens surrounding air which may reduce your symptoms. Simply opening the windows can also help, particularly if you are in an artificially heated building!

    Keeping your lids clean can help with dry and irritated eyes. Every morning and night, use a warm compress on your eyes. Holding this in place for a few minutes will improve the production and flow of oil from the glands in your lid. Gentle lid massage with a clean cotton wool bud will help the oils flow too. Then use special wipes or cotton wool and cooled boiled water to clean the edges of your lids and your lashes. Talk to your optician about whether lid hygiene might help you.

  • What should I eat to help with the symptoms of dry eye? Open

    Research shows that a diet high in omega-3 fats can help improve dry eye syndrome. Eat foods with omega-3s such as oily fish, like mackerel, salmon, sardines or herring. Omega-3s are also found in various nuts and seeds, vegetable oils, soya and soya products, and green leafy vegetables. Drink plenty of water too. You can also take omega-3 supplements to boost what you gain from your diet.
