You can buy prescription glasses and contact lenses easily in Thailand, from optical shops that are easy to find in shopping malls and town centers. Bring your current prescription, get a written quote, check the finished lenses before you pay the balance, and see an eye doctor at a hospital rather than a shop for anything beyond a simple update.
Many visitors and long-stay residents buy a spare pair or new sunglasses with their prescription while they are in Thailand. That is usually straightforward. What is less well known is how lightly the trade is regulated. A 2020 legal study by researchers at the National Institute of Development Administration found that Thailand has no law that sets out who may practice optometry, what training they need or what happens if they get it wrong.
This page covers eyewear only. If you are also thinking about dental work during your stay, our guide to dental treatment in Thailand covers the very different checks that apply there.

Who tests your eyes in a Thai optical shop
The person behind the counter may be a university-trained optometrist, and Thailand does have optometry degree programs, such as the one at Ramkhamhaeng University's Faculty of Optometry. But no law says that only a qualified optometrist may measure your eyes. Optometry is allowed under a Ministry of Public Health announcement from 2003, made under the healing arts law, and the 2020 study argued that this leaves the profession without proper control.
So do not take a framed certificate on the wall as proof of anything. Ask who will do the test and what their training is, and judge the shop on how carefully it works: a proper test takes time, checks each eye separately and asks about how you use your glasses.
Keep in mind what a shop test is. A refraction measures the lens strength you need. It is not a check of the health of your eyes. Sudden changes in vision, eye pain, flashes or new floaters, or a prescription that keeps changing are reasons to see an ophthalmologist, a medical doctor who specializes in eyes. Larger hospitals have eye departments; our guide to hospitals in Thailand explains how private and public hospitals work for foreigners.
Bring your prescription from home
The simplest way to get good glasses abroad is to arrive with your prescription and let the shop make lenses to it, rather than relying on a new test. In some countries you have a legal right to a copy: in the United States, for example, the Federal Trade Commission's Eyeglass Rule requires the prescriber to give you your glasses prescription after an eye exam, free and without you having to ask.
Before you leave home, make sure your copy shows:
- sphere, cylinder and axis for each eye;
- any reading addition (for varifocals or reading glasses) and prism;
- your pupillary distance (PD), the distance between your pupils, which the shop needs to center the lenses;
- a separate contact lens prescription if you wear contacts, since it includes the lens brand, base curve and diameter and is not the same as your glasses prescription.
A photo of the prescription on your phone works, but a paper copy avoids misreading.
Frames, lenses and the quote
Prices vary widely between mall chains, independent shops and branded boutiques, and they change often, so we do not print them. What decides the final price is mostly the lenses, not the frame: thinner high-index lenses, varifocals, anti-reflective and blue-light coatings and photochromic (light-reactive) lenses all add to the cost.
Ask for a written, itemized quote that lists the frame, the lens type and index, every coating and the date you can collect. Simple single-vision lenses are often made quickly; varifocals and strong prescriptions can take longer, so order early in your stay rather than two days before your flight.
Check the new lenses against the prescription before paying the balance. Ask the shop to measure the finished lenses on its lens meter and show you the reading next to your prescription. Then wear the glasses for a few minutes in the shop, looking at distance and at your phone.
Most mall shops take cards, and our guide to using cards in Thailand explains the fees. Ask whether a guarantee or free adjustment is included, and whether it is any use once you have left Thailand.
Contact lenses: medical devices, often sold like cosmetics
Thai law treats contact lenses as medical devices. A Ministry of Public Health notification on contact lenses was published in the Royal Gazette in 2010, and the Thai FDA's medical device division controls their import and sale, including a Thai label and leaflet. We found no Thai rule that requires a prescription to buy them, and the studies below found them sold in beauty shops and online with no advice at all, which is exactly why you need to be careful.
Colored "big eye" cosmetic lenses are the main problem. A 2020 study of colored monthly lenses bought from five shops in Ubon Ratchathani found that most were sold in beauty shops, not opticians, for an average of about 89 baht a pair. None of the sellers gave any advice or documentation, and the researchers found dirty products, unreadable labels and expired lenses. A 2021 study of lenses sold through an online marketplace found that buyers received instructions on use and storage, or warnings, in fewer than one case in five.
- Buy your usual brand and prescription from an optical shop, not a beauty stall or a social media seller.
- Check the box for the expiry date, an intact seal and a Thai label.
- Do not buy lenses you have never been fitted for. Lenses that fit badly can damage the surface of the eye.
- Treat cosmetic lenses as medical devices too. No prescription strength does not mean no risk.
Wearing contact lenses in a beach country
Thailand's sea, pools and heat add risks for lens wearers. The US Food and Drug Administration says to remove contact lenses before swimming and never to expose them to any water, whether tap, bottled, lake or sea water, because of the risk of serious eye infections, including Acanthamoeba keratitis, which is hard to treat. Never rinse lenses or the case with tap water, never top up old solution, and replace the case every three months.
For snorkeling or diving, a prescription mask avoids the problem; ask your eye care professional at home before you wear lenses anywhere near the water. Dust and the smoky season in the north can also irritate eyes, as our page on air pollution in Thailand explains.
A red, painful eye in a lens wearer needs a doctor the same day. The FDA advises taking the lenses out at once, keeping them in their case, and seeing an eye care professional. In Thailand, that means a hospital eye department, so check that your travel insurance covers emergency treatment before you need it.
For solution and other supplies, our guide to what you can buy over the counter in Thai pharmacies explains what Thai pharmacies sell. For sun protection for your eyes, sunglasses with UV protection belong on the list in our guide to heat and sun in Thailand.
Claiming VAT back on expensive glasses
Glasses bought from a shop in the VAT Refund for Tourists scheme can qualify for a refund of Thailand's 7 percent VAT, as long as you spend at least 2,000 baht in that shop on one day and get the P.P.10 form. The Revenue Department names glasses among the items that must be carried in your hand luggage and shown again after immigration if they cost 10,000 baht or more. Our guide to the VAT refund for tourists explains the steps.
Frequently asked questions
Is it cheap to buy glasses in Thailand?
Often, but prices vary widely between mall chains and independent shops, and the lenses decide most of the cost. Bring your prescription, compare written itemized quotes from two or three shops, and check what coatings are included before you agree a price.
Do I need a prescription to buy contact lenses in Thailand?
We found no Thai rule that requires one, and lenses are sold without one in beauty shops and online. Contact lenses are still medical devices under Thai law. Buy only the brand and prescription you have been fitted for, from an optical shop, and check the expiry date and seal.
Are optometrists licensed in Thailand?
Thailand has optometry degrees, but a 2020 legal study found no stand-alone law controlling who may practice optometry. Ask about the tester's training, and see an ophthalmologist at a hospital for anything beyond a routine update of your glasses.
How long does it take to get glasses made in Thailand?
It depends on the lenses. Simple single-vision lenses are often ready quickly, while varifocals and strong or unusual prescriptions take longer. Ask for the collection date in writing and order early in your trip so there is time for adjustments.
